Transfiguration of the Lord (6 August)

The name of the feast and its rank

The Roman Missal promulgated by Saint Paul VI entitles the Mass of 6 August In Transfiguratione Domini, "At the Transfiguration of the Lord", and gives it the rank of feast (festum)^[12]. The calendar of the French-speaking episcopal liturgical association assigns it the degree of "Feast of the Lord" and the colour white^[13]. A feast is celebrated only on the day itself; at Mass, the Gloria is sung, but the Credo is said only on Sundays and solemnities^[14]. The Credo is therefore proclaimed on 6 August only if the feast falls on a Sunday.

This rank is the endpoint of a long history. Extended to the whole Latin Church in 1457 with a "solemn double" office, the feast was raised in 1911 to the rank of "double of the second class", because the Archbasilica of the Lateran, mother of all churches, celebrates it as its titular feast; the 1960 rubrics classed it in the second class, and the 1969 calendar made it a feast of the Lord^{[15][16][17][18]}. These stages are detailed below, in the history of the feast.

A fixed-date feast that takes precedence over an Ordinary Sunday

Unlike Easter, the Ascension or Pentecost, the Transfiguration does not depend on the paschal computus: it always falls on 6 August, whatever the day of the week^[19]. When that day is a Sunday, a simple rule applies. In the table of precedence of the 1969 Universal Norms, "feasts of the Lord inscribed in the General Calendar" occupy the fifth rank, just before "Sundays of Christmas Time and Ordinary Time", in sixth place^[20]: the feast therefore takes precedence over the Sunday, and its Mass replaces the Sunday Mass.

The same Norms add an exception that shows the importance of these feasts. Ordinarily, a feast "is celebrated within the limits of the natural day" and has no First Vespers on the previous evening; but it is otherwise with feasts of the Lord that fall on a Sunday in Ordinary Time and replace its office^[21]. On Saturday 5 August in the evening, the Church already begins to sing the Transfiguration.

Since the reformed calendar came into force in 1970, this has happened eight times: in 1972, 1978, 1989, 1995, 2000, 2006, 2017 and 2023^[22]. Three of those Sundays have stayed in the Church's memory: Paul VI died on the evening of 6 August 1978, Benedict XVI commented on the feast at the Angelus of 6 August 2006, and Francis celebrated on 6 August 2023 the closing Mass of the Lisbon World Youth Day^[23][24][25]. That Sunday, the AELF published the Mass of the Transfiguration, with its two readings, its psalm and the Gospel of Saint Matthew^[26]. The following table gives, for the next ten years, the weekday on which the feast falls and the Gospel read at Mass according to the liturgical year.

Liturgical Year A begins on the preceding first Sunday of Advent: 2026 is a Year A, as were 2023 and will be 2029, and the Gospel of 6 August changes each year with it^[27][28].

Twice a year: 6 August and the Second Sunday of Lent

The Church does not wait for summer to meditate on the Transfiguration. Long before the feast of 6 August existed in Rome, the Roman liturgy read this Gospel at the beginning of Lent. Pope Saint Leo the Great, in the 5th century, preached a famous sermon on it, delivered, according to its ancient title, "on the Saturday before the Second Sunday of Lent"^[29]. Its editors, the Ballerini brothers, note that the Gospel capitularies, those ancient lists of Mass readings, assign this account to that Saturday alone, the Ember Saturday of spring^[30].

Callixtus III's bull still bears witness to this in 1457: it recalls that the universal Church already commemorated this miracle "on the Saturday of the first week of the Lenten fast and on the following Sunday"^[31]. The 1962 Roman Missal preserves this usage: the Gospel of the Transfiguration (Mt 17:1-9) is read there on the Lenten Ember Saturday, whose station is at Saint Peter's, then on the Second Sunday of Lent, whose station is at Saint Mary in Domnica^[32].

Since the 1969 reform, the Transfiguration gives the Second Sunday of Lent its Gospel and its preface. Each year, the account according to the evangelist of the year is read, and the preface of the day gives its meaning: "After he had foretold his own death to his disciples, he revealed his splendour to them on the holy mountain, so that it might be established, with the testimony of the Law and the Prophets, that through the Passion we come to the glory of the Resurrection"^[33]. The following table sets the readings of the Second Sunday of Lent alongside those of 6 August.

The two celebrations do not say the same thing. In Lent, the account sustains the journey toward Easter: the glory glimpsed on the mountain gives the courage to go up to Jerusalem, and the readings from Abraham recall that faith walks without seeing^[34][35][36]. On 6 August, the same scene is celebrated for itself, as a feast of light, with the book of Daniel and the eyewitness testimony of Saint Peter^[37].

Why 6 August?

No ancient document explains why the feast was placed on 6 August. The Gospels locate the episode only in relation to Peter's profession of faith: "six days after" according to Matthew and Mark, "about eight days after" according to Luke^[38]. What is certain is that the feast is Eastern in origin, that 6 August is its date in the Byzantine rite, and that most Latin Churches of the Middle Ages had adopted it, even though others celebrated it on 27 July, 17 March or 3 September^[39][40][41]. When Callixtus III fixed the feast for the whole Church "on the eighth day before the Ides of August, which is the sixth day of that month", he ratified the most widespread date; he did not create it^[42][43].

An explanation circulates in the Russian tradition. A manual for country pastors, published in Kiev in 1893, asserts that the feast was moved out of Lent, whose penance ill suited its joy, and placed forty days before the Exaltation of the Holy Cross of 14 September, because the Transfiguration is said to have preceded the crucifixion by forty days^[44]. The explanation is attested by no known ancient source; yet it has the merit of binding the feast to the Cross, as the Byzantine liturgy itself does, which sings that the disciples saw Christ's glory "so that, when they would see him crucified, they would understand that his Passion was voluntary"^[45].

The date has received, on the other hand, over the centuries, a neighbourhood that gives it meaning. In the Byzantine rite, 6 August falls during the fast that prepares the feast of the Dormition of the Mother of God on 15 August, and the calendar of the Orthodox Church in America makes it the second of the three "feasts of the Saviour" in August, after the procession of the wood of the Cross on 1 August^[46][47][48]. In the Roman calendar, the feast stands between the dedication of the Basilica of Saint Mary Major on 5 August and the commemoration of Pope Saint Sixtus II and his martyr companions on 7 August; until 1969, Sixtus II, put to death on 6 August 258, shared the very day of the Transfiguration^[49][50][51].

The Transfiguration is one of the mysteries most anciently meditated upon by the Church, but one of the last great feasts of the Lord to have received its own day in the whole West. Its history follows three paths: a place, Mount Tabor, where the Christians of Jerusalem located the event; a feast born in the Eastern Churches; a victory in 1456 that decided a pope to give it to the whole Latin Church.

The feast in a few dates

Tabor, mountain of the feast

The Gospels speak only of "a high mountain" (Mt 17:1; Mk 9:2) or "the mountain" where Jesus went up to pray (Lk 9:28), and Saint Peter calls it "the holy mountain" (2 Pet 1:18)^[52]. As early as the 4th century, the Church of Jerusalem gives it a name. In the twelfth of his catecheses, delivered around 348-350, Saint Cyril of Jerusalem reminds his hearers that Moses and Elijah were present beside the Lord "when he was transfigured on Mount Tabor"; his French translator of 1715 noted that "at Jerusalem there was no doubt" about this place^[53]. In 404, Saint Jerome recounts that Saint Paula, in the course of her pilgrimage, climbed "Mount Tabor, on which the Lord was transfigured"^[54].

The summit is soon covered with sanctuaries. Around 570, a pilgrim from Piacenza finds there "three basilicas, there where the disciple said: Let us make three tents here"^[55]. A century later, the Gallic bishop Arculf, whose account was written down by Adomnan, abbot of Iona, describes a great monastery and three churches "according to the number of the tents" of which Peter spoke, all surrounded by a stone wall^[56]. A document from the time of Charlemagne counts four churches served by eighteen monks; in 1101, the crusaders entrust the mountain to the Benedictines^[57].

The sanctuaries do not survive the wars. Saladin plunders Tabor, and Sultan Baybars razes all its churches in 1263; for more than three centuries, few are the pilgrims who venture onto that isolated summit^[58]. After 1620, when the Franciscans settle in Nazareth, pilgrims climb it every year on 6 August, for the feast; in 1631, the Druze emir Fakhr ad-Din allows them to open a community there, and the same concession is made shortly after to the Greek Orthodox^[59]. The custom has been preserved: on the eve of the feast, Christian families of Galilee spend the night in tents around the sanctuary, a memory of Ottoman times when the friars were allowed to go up only once a year, for the Transfiguration^[60].

The present church, in Syro-Romanesque style, was built by the Franciscans from 1921 to 1924; it is the first work of the architect Antonio Barluzzi, and its two bell towers rise over the former oratories of Moses and Elijah, whose chapels remain dedicated to them^[61]. On 6 August 2023, the Custos of the Holy Land, Brother Francesco Patton, opened there with a holy door the jubilee of the basilica's centenary^[62]. Tabor remains the traditional place of the event; the objections raised against this identification, including the Mount Hermon hypothesis, belong to the study of the Gospel account^[63].

A feast born in the East

The oldest known celebration comes from Jerusalem. By publishing in 1955 an unpublished homily of Saint Anastasius the Sinaite on the Transfiguration, the historian André Guillou showed that the feast appeared in the calendar of the Church of Jerusalem in the 7th century^[64]. Anastasius, priest and monk of Mount Sinai, lived toward the end of that century^[65]; one of his homilies on the Transfiguration, "It is good for us to be here", is still read in the Liturgy of the Hours of 6 August^[66].

For Constantinople, it was long repeated that the feast had been created by the Byzantine emperor Leo VI the Wise (886-912), on the authority of the monk Nicon of the Black Mountain and the Patriarch of Constantinople Nicholas III^[67]. The Byzantinist Venance Grumel set this opinion aside in 1956: a Sinai Gospel book dated 710 or 755, an 8th-century menologion, a Gospel book of 835, the calendar of Naples (847-877) and other Greek books older than Leo the Wise already mention the feast^[68]. His conclusion is clear:

"Thus, the feast of the Transfiguration goes back well beyond Leo the Wise, namely at least to the beginning of the 8th century." — Venance Grumel, "Sur l'ancienneté de la fête de la Transfiguration", Revue des études byzantines, 1956^[69]

What Leo the Wise did was, according to Grumel, to raise its solemnity. The two ancient witnesses speak of it in connection with the Dormition fast: certain faithful, "under pretext of honouring the feast of the Transfiguration newly established by Leo the Wise", broke that fast, which presupposes a feast already known but recently enhanced^[70]. Today, the Transfiguration counts among the twelve great feasts of the Byzantine year, with the Exaltation of the Cross, Theophany, the Meeting of the Lord in the Temple or the Dormition^[71].

Among the Armenians: Vardavar

The Armenian Church celebrates the Transfiguration not on a fixed date, but on the fourteenth Sunday after Easter, ninety-eight days later, so that the feast moves between 28 June and 1 August^[72]. It is one of the five principal feasts of the year and lasts three days: Sunday is the main feast, Monday is still a feast day with the commemoration of the departed, and Tuesday closes the observance^[73]. At the beginning of the 20th century, Frederick Holweck noted that it was preceded by a six-day fast^[74].

In Armenia it is also called Vardavar, the "feast of roses", after an ancient pagan feast it replaced^[75]. Around 690, the Armenian bishop Gregory Archarouni attributed this replacement to Saint Gregory the Illuminator, the apostle of Armenia, and explained that the name had been kept "because Christ opened his glory like a rose on Mount Tabor"^[76]. Holweck noted, however, that the feast is absent from the two ancient Armenian calendars published by the orientalist Frederick Conybeare^[77].

In the other Eastern Churches

In the Syriac Church, the Transfiguration was, in Holweck's testimony, a first-class feast, and among the Byzantines a feast with vigil and octave^[78]. The Byzantine calendar indeed prepares it with a forefeast on 5 August, whose troparion invites the faithful to go out to meet the Transfiguration of Christ, and prolongs it until its solemn leave-taking on 13 August^[79][80]. For the day itself, the Orthodox Church in America offers for reading the homily of Gregory Palamas, Archbishop of Thessalonica in the 14th century, on the Transfiguration^[81].

The feast has kept a rural custom in the East: Greeks and Russians bless grapes and other fruits on it^[82]. Rome knew a similar usage, since the pope, at the Mass of the feast, took new wine or pressed a ripe cluster into the chalice^[83]. These first fruits brought to the transfigured Christ recall that "creation itself" waits to be set free to enter into the freedom and glory of the children of God (Rom 8:21).

The West adopts the feast

The Latin West took time to receive the feast. According to Holweck, it appears in no Western book before the mid-9th century; it enters the liturgy of many dioceses around the 10th century, most often on 6 August, but in Gaul and England on 27 July, at Meissen on 17 March and at Halberstadt on 3 September^[84]. Rome already read the Gospel of the Transfiguration on the Lenten Ember Saturday and the following Sunday, and it is this usage that the bull of 1457 will call the "common commemoration" of the universal Church^[85][86].

On the eve of 1456, the feast is therefore widespread, but it is not universal, and Callixtus III's bull says so without detour. The Church, the pope writes, already celebrates the Visitation, Our Lady of the Snows and the Purification of the Virgin, the Presentation in the Temple, where the Saviour showed himself son of man, the Circumcision, where he observed the Law, and several feasts of saints instituted "quite recently"; it is therefore fitting to honour also each year the day when he revealed himself "Lord of the Law and the Prophets" and manifested "not the weakness of the flesh, but the power of glorification"^[87].

Belgrade, 1456: the victory that made the feast universal

Three years after the fall of Constantinople in 1453, Sultan Mehmed II besieges Belgrade, fortress of the kingdom of Hungary standing on the Danube, at the confluence of the Sava^[88][89]. For Pope Callixtus III, who had made the crusade the great project of his pontificate, the fall of the city would open the road of Christian Europe to the Ottoman armies, and he calls all Christendom to prayer^[90].

All Christendom at prayer

On 29 June 1456, on the feast of Saints Peter and Paul, Callixtus III addresses a bull to all patriarchs, archbishops, bishops and abbots^[91]. In it he asks for prayers, fasts and penance to "return to the Lord, that he may return to us", processions on the first Sunday of each month, the Mass "against the pagans" and, at every Mass, a prayer for the protection of the Christian people^[92]. So that all the faithful may join in, he further prescribes that, in every church, between noon and vespers, one or more bells ring as for the Angelus, while three Our Fathers and three Hail Marys are recited^[93].

This ringing later gave birth to a tenacious legend: the pope is said to have rung the bells against the comet that appeared that summer, and even to have excommunicated it. The historian of the popes Ludwig von Pastor, who worked on the registers of the Vatican Secret Archives, judges it unworthy of refutation^[94].

The siege and the deliverance

The Christians are led by the voivode John Hunyadi; at his side fight the crusaders raised by the preaching of the old Franciscan Saint John of Capistrano, whom the bull of 1457 describes as common folk, fewer than the enemy and almost without weapons^[95][96]. On 22 July 1456, these crusaders hurl themselves against the Turkish camp without having received the order; Capistrano, who tries in vain to hold them back, goes down among them, and Hunyadi makes a fresh sortie to rescue them^[97]. By nightfall, the sultan, wounded by an arrow, gives the signal to retreat, and his whole camp falls into Christian hands^[98].

"On the day of Saint Mary Magdalene, the Cross of Christ triumphed over its enemy." — Nicholas of Cusa, sermon reported by Ludwig von Pastor, History of the Popes^[99]

Callixtus III's bull retains the same image: the name of Christ Jesus invoked with one voice by the whole besieged people, the standard of the Cross raised to heaven "with loud cries and tears", and the victory obtained "on that memorable day of Blessed Mary Magdalene"^[100]. The two victors did not long survive. An epidemic, probably born of the heat and of bodies left unburied, carried off John Hunyadi on 11 August; Saint John of Capistrano died on 23 October at Ilok, where he was buried^[101].

The news reaches Rome on 6 August

According to Pastor, the first news of the victory reached Rome on 6 August 1456^[102]. That day was already, in much of the West, the day of the Transfiguration^[103]. The coincidence caused a lasting error: the chroniclers Bonfini and Bernino believed the battle fought on 6 August, and the historian Ferdinand Gregorovius placed it on 9 August, whereas the best witnesses give 22 July^[104].

The bull Inter divinae dispositionis arcana

A year later, to the day, after deliberating with the cardinals in secret then public consistory, Callixtus III publishes at Saint Peter's in Rome the bull Inter divinae dispositionis arcana, dated 6 August 1457^[105]. It institutes the feast of the Transfiguration for all the faithful and for ever, "on the eighth day before the Ides of August, which is the sixth day of that month"^[106]. It asks the bishops to celebrate and have celebrated each year this feast, "commonly called the feast of the Saviour", with a "solemn double" office sent with the bull itself; Holweck reports that the pope had composed that office himself^[107][108].

The text is not first a victory bulletin: it is an exposition of the mystery. The Transfiguration, the bull says, shows "in one and the same person the power of divinity and the true nature of man"; it confirms faith, hope and charity; it strengthened the apostles to believe their Master's passion not imposed by the power of his adversaries, but accepted by his own will^[109]. The victory of Belgrade comes next, as a blessing for which God must be thanked each year:

"As the children of Israel, delivered from the bondage of Egypt, celebrated that ever-memorable day and rendered to God the praises and thanksgivings they owed him, so, in this solemnity and principal feast of the Transfiguration of our Lord Jesus Christ, may all peoples, recalling its mysteries, its miracles and the testimony of all the holy and undivided Trinity, apply themselves also to venerating and celebrating this day of joy for the victory obtained." — Callixtus III, bull Inter divinae dispositionis arcana, 6 August 1457^[110]

The pope attaches indulgences to the feast: one hundred days for attendance at vespers, matins or Mass on the vigil and the day, in churches where the new office will be celebrated, forty days for each of the little hours, and, for whoever celebrates the octave, above all in churches dedicated to the Saviour, the same favours as for the octave of Corpus Christi^[111]. Several briefs press its application: one to Cardinal legate Juan Carvajal, others to his representatives in Aragon on 24 September 1457, and in Germany on 30 November^[112].

The pope dies on the day of the feast

Callixtus III saw only once the feast he had given to the Church. On 6 August 1458, on the evening of the Transfiguration, he died in Rome^[113]. His pontificate left two gestures of prayer linked to Belgrade: the ringing of bells at noon, asked to sustain the defenders of the city, and 6 August, given to the whole Church as a day of light and thanksgiving^[114][115].

The rank of the feast, from 1911 to 1969

In reforming the breviary, Saint Pius X raises the feast in 1911, for a reason close to Rome's heart: the Archbasilica of the Lateran, "mother and head of all the churches of the City and of the world", celebrates the Transfiguration as its titular feast, besides the great solemnity of Easter^[116]. The rubrics published with the constitution Divino afflatu therefore decide that the feast will be celebrated by the whole clergy, secular and regular, as a "double of the second class"^[117].

The 1960 code of rubrics keeps this rank under the name "second-class feast": the 1962 Roman Missal inscribes on 6 August the Transfiguration of Our Lord Jesus Christ, with the commemoration of the holy martyrs Sixtus II, Felicissimus and Agapitus^[118]. Pope Saint Sixtus II had indeed been put to death on 6 August 258, with four of his deacons, during the persecution of Valerian, as attested by an almost contemporary letter of Saint Cyprian^[119].

The calendar promulgated by Saint Paul VI on 14 February 1969 makes the Transfiguration a feast of the Lord, in the fifth rank of the table of precedence, and moves to 7 August the commemoration of Sixtus II and his companions, who thus keep their own day^[120][121]. It is still the calendar in force, as current liturgical calendars show^[122].

On 6 August, the whole prayer of the Church is turned toward the light of Tabor: the Mass, the Liturgy of the Hours, and, in the East, the Divine Liturgy and its hymns. Each text takes up a trait of the Gospel account and gives it a meaning for the one who prays.

The Mass of 6 August

The Mass opens with an antiphon that condenses the whole mystery. Inspired by Saint Matthew, it names the three divine Persons: "In a resplendent cloud the Holy Spirit appeared, the voice of the Father was heard: This is my beloved Son, in whom I have placed all my love: listen to him"^[123]. Then the Gloria is sung, as at all feasts^[124].

The opening prayer takes up the ancient collect of the feast, which the 1962 Missal still gave; the 1970 reform changed only its ending, to ask that we listen to the voice of the Son so as to share his inheritance^[125][126]. The same collect concludes the offices of the day, and the French translation of the Liturgy of the Hours renders it thus:

"O Lord, in the Transfiguration of your Christ, you confirmed by the testimony of Moses and Elijah the truth of the mysteries of the faith, and you foretold our wonderful adoption; grant us to listen to the voice of your beloved Son, so that we may one day share his inheritance with him." — Collect of the Transfiguration of the Lord, Liturgy of the Hours, liturgical translation of the AELF^[127]

The other prayers unfold the same hope. Over the offerings, the priest asks God to sanctify them "through the glorious Transfiguration of your Only Son" and to purify us from the stains of sin "through the splendours of his illumination"^[128]. The communion antiphon is a promise of Saint John: "When Christ appears, we shall be like him, for we shall see him as he is" (1 Jn 3:2)^[129]. The prayer after communion draws the consequence: may the heavenly food received "transform us into the image" of him whose splendour God willed to manifest in his glorious Transfiguration^[130].

The preface, echo of a sermon by Saint Leo

The 1970 Missal gives the feast a proper preface, absent from the 1962 Mass^[131][132]. It says in a single sentence why Christ was transfigured:

"Before chosen witnesses, he revealed his glory, and he clothed with dazzling splendour that body like the body of all men, to take away from the hearts of the disciples the scandal of the cross and to show that what first shone forth in the Head will be fulfilled in the whole body of the Church." — Preface of the Transfiguration of the Lord, Roman Missal^[133]

The drafters drew this sentence from Saint Leo the Great. In his sermon on the Transfiguration, delivered in Rome in the 5th century, the pope writes that the principal purpose of the event was "to take away from the hearts of the disciples the scandal of the cross", and that it founded the hope of the Church, so that the whole body of Christ might know what transformation would be given to it and the members might promise themselves a share of the honour "which had shone forth in the Head"^[134]. The first Latin formula of the preface takes up the sermon's wording word for word, and the second keeps its image of the Head where glory first shone forth^[135][136].

The readings of the Mass

On a weekday, the Mass has a single reading before the Gospel, at choice: the book of Daniel or the second letter of Saint Peter; on Sunday, both are read^[137][138]. After the first reading, Psalm 96 is sung, with this refrain: "The Lord is king, the Most High over all the earth", and this verse that seems written for Tabor: "When his lightnings illumined the world, the earth saw and was terrified"^[139].

Daniel and the Son of Man

The reading from the book of Daniel reports one of his visions: an Ancient One whose "clothing was white as snow" takes his place on a throne of fire, and behold, there comes, "with the clouds of heaven, one like a Son of Man", who receives "dominion, glory and kingship", a kingship "that shall not be destroyed" (Dan 7:9-10, 13-14)^[140]. The choice of this text illumines the Gospel. On the mountain, Jesus' garments become white as light, a cloud appears, and, coming down, Jesus calls himself "the Son of Man" who must rise from the dead (Mt 17:2, 5, 9)^[141]. The glory Daniel saw from afar has drawn near, and it has a face.

Peter, eyewitness

The other reading is the testimony of one of the three apostles present. Saint Peter writes to Christians who have not seen the Lord, and he guarantees them that he has not followed fables:

"For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty. [...] This voice from heaven we ourselves heard when we were with him on the holy mountain." — Saint Peter, second letter, 2 Pet 1:16, 18^[142]

The apostle concludes that the prophetic word receives confirmation from it: we must hold to it "as to a lamp shining in a dark place until the day dawns and the morning star rises in your hearts" (2 Pet 1:19)^[143]. The feast thus becomes an act of faith in a testimony: what Peter saw, the Church believes on his word.

Three evangelists, one same mountain

The Gospel changes according to the liturgical year, and each evangelist brings traits of his own. The following table sets them side by side, as the lectionary has them heard on 6 August and on the Second Sunday of Lent.

The three accounts agree on the essential: three chosen disciples, a high mountain, the shining face and garments, Moses and Elijah, Peter's word about the tents, the cloud and the voice of the Father^{[144][145][146]}. The differences of detail, which tradition receives as complementary testimonies, are studied in the article The Transfiguration.

The Liturgy of the Hours of 6 August

The office of the day opens with an antiphon that greets Christ as light itself: "Holy light, splendour of the Father, praise to you, Jesus Christ"^[147]. At the office of readings, the hymn "We have left" ends with this request: "Lord, Son of God, lead us to the Father, transfigure our lives"; then come Psalms 83, 96 and 98, the last of which the antiphon sums up with "bow down before his holy mountain", evoking Moses to whom God spoke "in the pillar of cloud"^[148].

The biblical reading is the passage from the second letter to the Corinthians in which Saint Paul contrasts the veiled face of Moses, which shone with a "passing" glory, with the unveiled face of Christians: "And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another" (2 Cor 3:18)^[149]. The reading ends on this verse: "For God, who said, 'Let light shine out of darkness,' has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ" (2 Cor 4:6)^[150].

Then comes the homily of Saint Anastasius the Sinaite, "It is good for us to be here". The Sinai monk presents the Transfiguration as "a prefigurative image of the kingdom of heaven" and invites each believer to climb the mountain with Christ:

"What is happier, what is more sublime, what is nobler than to be with God, than to be transfigured into God in the light? [...] There are presented as in a mirror the firstfruits and images of all the eternity to come." — Saint Anastasius the Sinaite, homily for the Transfiguration, office of readings of 6 August^[151]

The office of readings ends with the Te Deum, sung on feast days^[152]. At lauds, the three antiphons follow the account: "The face of Jesus shone like the sun, his garments became white as snow"; "For us Christ is transfigured, Elijah and Moses speak with him, the voice of his Father bears witness to him"; "In the glory of the mountain, the Law and the prophets bore witness to him"^[153]. The intercessions have for refrain a verse of Psalm 35: "In your light, we see light!"^[154]

At vespers, the hymn "Today, clothed with light" is followed by Psalm 109, Psalm 120, "I lift up my eyes to the hills: from where will help come to me?", and the canticle of the first letter to Timothy on Christ "manifested in the flesh"^[155]. The antiphon of the Magnificat gathers the whole feast: "Rise! Have no fear! The glory of the Lord has appeared on the face of Christ, his light has shone in our hearts, alleluia"^[156].

The pre-1970 Mass

The 1962 Roman Missal gave the feast a Mass very different in detail, but similar in spirit^[157]. The introit began with a verse of Psalm 76: "Your lightnings illumined the world, the earth trembled and shook", followed by Psalm 83, "How lovely are your dwellings, Lord of hosts!"; the Latin word of the psalm, tabernacula, is the very word the Gospel uses for the three tents Saint Peter wanted to pitch^[158]. The epistle was already Peter's testimony (2 Pet 1:16-19) and the Gospel Saint Matthew's account; the Credo was said^[159].

The chants between the readings celebrated the beauty of the Son. The gradual took up Psalm 44: "You are the most handsome of the children of men, grace is poured upon your lips"; the alleluia quoted Wisdom: "A reflection of eternal light, a spotless mirror, an image of his goodness" (Wis 7:26)^[160]. The communion antiphon took up the order given coming down from the mountain: "Tell no one the vision you have seen, until the Son of Man has risen from the dead" (Mt 17:9), and the postcommunion asked to grasp "with the understanding of a purified mind" the mysteries celebrated^[161]. Each collect was followed by that of the martyrs Sixtus II, Felicissimus and Agapitus^[162].

In the Eastern Churches

In the Byzantine rite, two hymns sum up the feast. The first, the troparion, is a prayer to be enlightened oneself:

"You were transfigured on the mountain, O Christ God, showing your disciples your glory as much as they could bear. Make your eternal light shine upon us sinners also, through the prayers of the Mother of God. Giver of light, glory to you!" — Troparion of the Transfiguration, tone 7, Byzantine liturgy^[163]

The second, the kontakion, explains why the apostles saw this glory. The Catechism of the Catholic Church quotes it in full, a sign that the Latin Church makes this prayer of the East its own:

"You were transfigured on the mountain, and, as much as they were capable, your disciples beheld your Glory, Christ God, so that when they would see you crucified, they would understand that your Passion was voluntary and would proclaim to the world that you are truly the radiance of the Father." — Kontakion of the Transfiguration, Byzantine liturgy, quoted by the Catechism of the Catholic Church, no. 555^[164]

In the homily on the Transfiguration that the Orthodox Church in America offers for this day, Gregory Palamas pauses over a difference between the Gospels: Matthew and Mark say "six days after", Luke "about eight days after". The Archbishop of Thessalonica sees a mystery in it rather than a contradiction:

"The great vision of the light of the Transfiguration of the Lord is the mystery of the eighth day, that is, of the age to come, which will be revealed after the passing of the world created in six days." — Gregory Palamas, homily on the holy Transfiguration^[165]

The eighth day is thus, for Palamas, the one that comes after the week of Creation: the age to come. To read the Transfiguration as a flash of that day is to say with the Catechism that the light of Tabor is "a foretaste of the Kingdom", not a mere memory^[166][167].

The liturgy, the Fathers and the Catechism read in the event of Tabor six truths, which hold together: the divinity of the Son manifested in his flesh, the Cross illumined in advance, the whole Trinity, the harmony of the two Testaments, the call to listen to the Son, and the glory promised to our bodies.

The glory of the Son shown "for an instant"

The Catechism places the Transfiguration at the moment when Jesus begins to announce his Passion. Peter has just confessed him as the Christ, the Son of the living God; then, the Catechism says, "for an instant, Jesus shows his divine glory, thus confirming Peter's confession"^[168]. What shines on the mountain is not a light come from elsewhere and laid upon him: it is the glory of him who is God, made visible in a human body. The bull of 1457 already said this, seeing in the Transfiguration the manifestation, "in one and the same person, of the power of divinity and the true nature of man"^[169].

Why did that body not always shine thus? Saint Thomas Aquinas answers with a simple image. From his conception, the soul of Christ possessed glory; but, by a disposition willed by God, that glory did not overflow onto his body, so that he could accomplish the mysteries of our redemption in flesh capable of suffering^[170]. On Tabor, Christ let pass into his body for an instant the brightness that came from his divinity and from the glory of his soul, not as a quality settled in him, but "in the manner of a passing impression, as when the air is illumined by the sun"^[171]. It was, Thomas concludes, a miracle, in the same way as Christ's walking on the waters^[172].

The distinction matters. According to Thomas, that brightness was indeed the brightness of glory "as to its essence", but not "as to its manner of being": in risen bodies, glory will be a permanent quality, whereas on Tabor it was only a passing^[173]. The apostles therefore saw the true glory, the one that awaits the elect, but shown only for the time needed for them to remember it.

The scandal of the Cross removed in advance

The Transfiguration comes shortly before the ascent to Jerusalem. The Catechism gives its purpose in one sentence: its end is "to strengthen the faith of the apostles in view of the Passion: the ascent onto the 'high mountain' prepares the ascent to Calvary"^[174]. Saint Leo the Great, in the sermon the Church reads on the Second Sunday of Lent, had said it with still greater force:

"By this transfiguration he wished above all to forearm his disciples against the scandal of the cross and, by revealing to them all the greatness of his hidden dignity, to prevent the abasements of his voluntary passion from shattering their faith." — Saint Leo the Great, sermon on the Transfiguration, office of readings of the 2nd Sunday of Lent^[175]

The three apostles of Tabor are also those Jesus will take with him to Gethsemane (Mk 14:33), and the glory they saw was to enable them to understand that the Cross was not a defeat suffered. The Byzantine kontakion, quoted by the Catechism, sings that the disciples contemplated Christ's glory "so that when they would see you crucified, they would understand that your Passion was voluntary"^[176]; the bull of 1457 says the same^[177].

Saint Thomas adds a reason that touches every Christian. The Lord had just invited his disciples to follow him on the way of his Passion; yet one does not walk straight toward a goal one does not know:

"To walk straight on a path, one must know the goal in advance, in a certain way, just as the archer does not loose his arrow straight unless he has first looked at the target. And this is above all necessary when the path is hard and rough, the walking painful, but the end joyful." — Saint Thomas Aquinas, Summa Theologiae, IIIa, q. 45, a. 1^[178]

Tabor is that glimpsed target. Thomas cites Saint Bede the Venerable in support: by a loving foresight, the Lord allowed his disciples to taste for a moment the contemplation of eternal joy, so that they might more valiantly bear adversity^[179].

The whole Trinity appeared

Tabor answers the Jordan. At Jesus' baptism, the Father had spoken and the Spirit had descended like a dove; on the mountain, the Father speaks anew, and the Spirit shows himself in the luminous cloud. The Catechism, after Saint Thomas, sums up the scene:

"The whole Trinity appeared: the Father in the voice, the Son in the man, the Spirit in the luminous cloud." — Saint Thomas Aquinas, Summa Theologiae, IIIa, q. 45, a. 4, ad 2, quoted by the Catechism of the Catholic Church, no. 555^[180][181]

Thomas explains the parallel. At baptism, which is the mystery of the "first regeneration", the action of the whole Trinity was shown, and the dove signified the innocence baptism gives; at the Transfiguration, which is the mystery of the "second regeneration", the luminous cloud signifies the brightness of glory and the refreshment from all evil that God will give his elect in the resurrection^[182]. The bull of 1457 had found a striking formula for the same scene: the Father making his voice heard like thunder, the Son shining forth, the Holy Spirit covering with the cloud and illumining^[183].

Pope Leo XIV took up this parallel at the Angelus of the Second Sunday of Lent 2026, rereading the mountain as a new Jordan: the voice of the Father proclaiming his beloved Son and the luminous cloud where the Holy Spirit stands manifest the joint action of the three Persons^[184]. The feast of the Transfiguration is thus, with the feast of the Baptism of the Lord and the solemnity of the Holy Trinity, one of the great days when the liturgy contemplates the three divine Persons acting together.

The Law and the Prophets bear witness

Moses and Elijah are not there by chance. Both had been admitted to an encounter with God on the mountain, Moses on Sinai and Elijah on Horeb (Ex 33:18-23; 1 Kings 19:8-13), and both represent what God had said before Christ. The Catechism stresses it: "Moses and Elijah had seen God's glory on the Mountain; the Law and the prophets had announced the Messiah's sufferings"^[185]. Saint Luke even specifies the subject of their conversation: they spoke with Jesus "of his departure, which he was to accomplish at Jerusalem" (Lk 9:31)^[186].

Saint Leo the Great sees in their presence a proof given to the apostles. Moses and Elijah, "that is, the Law and the Prophets", converse with the Lord, and the rule of Scripture according to which every word is established on two or three witnesses is fulfilled^[187]:

"The writings of the one and the other Covenant, indeed, guarantee each other; he whom the prefigurative signs had promised under the veil of mysteries is shown as manifest and evident by the splendour of his present glory." — Saint Leo the Great, sermon on the Transfiguration^[188]

The liturgy of 6 August takes up this theme in several places: the collect recalls that God "confirmed by the testimony of Moses and Elijah the truth of the mysteries of the faith", and a lauds antiphon sings that, "in the glory of the mountain, the Law and the prophets bore witness to him"^[189][190]. Leo XIV said it again in his own way in 2026: between Moses and Elijah, Christ fulfils in his person the Law and the Prophets^[191].

"Listen to him"

The Father's only word, in the whole scene, is an order and a declaration of love: "This is my beloved Son, with whom I am well pleased; listen to him!" (Mt 17:5)^[192]. The Father does not ask the apostles to stay on the mountain or to pitch tents; he asks them to listen to the one who will go down with them toward Jerusalem. The collect of the feast makes this word the Church's principal request: "grant us to listen to the voice of your beloved Son, so that we may one day share his inheritance with him"^[193].

Saint Leo drew from that voice a rule of life for ordinary days as for days of trial: "Whether it is a matter of practising the commandments or of bearing adversity, the voice of the Father which we have just heard must unceasingly resound in our ears"^[194]. Saint John Paul II, in his letter on the Rosary, sees in this listening what prepares the apostles to live the Passion "in order to come with him to the joy of the Resurrection and to a life transfigured by the Holy Spirit"^[195].

The sacrament of the second regeneration

The Catechism sets side by side two thresholds of Jesus' life: "On the threshold of public life: Baptism; on the threshold of Easter: the Transfiguration"^[196]. It borrows from Saint Thomas a difficult expression, which must be explained:

"By Christ's Baptism 'was manifested the mystery of our first regeneration': our Baptism; the Transfiguration 'is the sacrament of the second regeneration': our own Resurrection." — Catechism of the Catholic Church, no. 556, quoting Saint Thomas Aquinas^[197]

In other words, man is called to be born twice to the life of God. The first birth is baptism, which gives the life of grace to the soul; the second will be the resurrection, which will give glory to the body itself. The Transfiguration is called the "sacrament" of that second birth in the ancient sense of the word: a sign that shows it in advance. The Catechism continues: it "gives us a foretaste of Christ's glorious coming, 'when he will change our lowly body to be like his glorious body' (Phil 3:21)", but it also recalls that "through many tribulations we must enter the kingdom of God" (Acts 14:22)^[198].

Saint Paul VI had written for the Angelus of 6 August 1978, which he could not deliver, a meditation on this precise point:

"This body transfigured before the amazed eyes of the apostles is the body of Christ our brother, but it is also our body destined for glory. This light which floods it is and will also be our share of inheritance and splendour. We are called to share in so great a glory because we are 'partakers of the divine nature' (2 Pet 1:4)." — Saint Paul VI, text prepared for the Angelus of 6 August 1978^[199]

The Greek Fathers said the same hope with the word divinisation. Saint Anastasius the Sinaite, in the homily read on 6 August, promises: "with him, like him, we shall be transfigured, divinised for ever"^[200]. The bull of 1457, for its part, read in Christ's white garments the sign of his mystical body, the universal Church, and concluded that on the last day, when "the righteous will shine like the sun", then at last the whole mystery of the Transfiguration will be unveiled^[201]. The Catechism says it soberly: Christ, Head of the Church, "manifests what his Body contains and radiates in the sacraments: 'the hope of glory'"^[202].

The feast of 6 August has not stayed shut inside the missal. The popes of the 20th and 21st centuries have made it a mystery to pray in the Rosary, an icon of consecrated life, a date of their own lives, and a message addressed to young people.

The fourth luminous mystery of the Rosary

On 16 October 2002, Saint John Paul II added to the Rosary five "luminous mysteries", drawn from the public life of Christ: his baptism in the Jordan, the wedding at Cana, the proclamation of the Kingdom, the Transfiguration and the institution of the Eucharist^[203]. The apostolic letter Rosarium Virginis Mariae proposes meditating them on Thursdays^[204]. Among these five mysteries, the pope singles out one:

"The Transfiguration is the luminous mystery par excellence. According to tradition, it took place on Mount Tabor. The glory of divinity shines on the face of Christ, while, to the Apostles in ecstasy, the Father gives him to be recognised so that they may 'listen to him' and prepare themselves to live with him the sorrowful moment of the Passion, in order to come with him to the joy of the Resurrection and to a life transfigured by the Holy Spirit." — Saint John Paul II, Rosarium Virginis Mariae, no. 21^[205]

The same letter opens almost on the scene of Tabor. At the beginning of the first chapter, under the title "A face radiant as the sun", John Paul II writes that the episode of the Transfiguration, "in which the three Apostles Peter, James and John appear as ravished by the beauty of the Redeemer, can be considered as an icon of Christian contemplation"^[206]. To pray the Rosary, for him, is to do what the apostles did on the mountain: to fix one's eyes on the face of Christ, with Mary^[207].

An icon of consecrated life

Six years earlier, in the apostolic exhortation Vita consecrata of 25 March 1996, the same pope had chosen the Transfiguration as the image of every life given to God. To grasp the essential traits of that vocation, he wrote, "it is particularly useful to fix one's gaze on the radiant face of Christ in the mystery of the Transfiguration"^[208]. The episode presupposes "an 'ascent of the mountain' and a 'descent from the mountain'": the disciples, for a moment enveloped by the splendour of Trinitarian life, are then brought back to ordinary life, where they see no more than "Jesus alone" in the humility of his human nature^[209].

"Like the three chosen apostles, the Church contemplates the transfigured face of Christ, to be strengthened in faith and not risk being dismayed before his disfigured face on the Cross." — Saint John Paul II, Vita consecrata, no. 15^[210]

Peter's word, "it is good that we are here", becomes in the same text the prayer of every consecrated person: "how beautiful it is for us to stay with you, to give ourselves to you, to concentrate our existence on you in an exclusive way!"^[211]. A little further on, the exhortation entitles one of its parts "From Tabor to Calvary", and recalls that the dazzling event of the Transfiguration "prepares the other event, tragic, but no less glorious, of Calvary"^[212].

6 August 1978: Paul VI dies on the evening of the feast

Saint Paul VI had a special bond with this feast. His first encyclical, Ecclesiam suam, is signed "from the Vatican, 6 August 1964, on the feast of the Transfiguration of Our Lord Jesus Christ"^[213]. Fourteen years later, on 6 August 1978, a Sunday, he was at Castel Gandolfo, ill; he had written the text of the midday Angelus, but he could not deliver it before the pilgrims^[214]. According to the note joined by the Holy See to the Italian version of that text, he "entered into the peace of the Lord" that same evening, at 9:40 p.m., "Sunday 6 August, Transfiguration of the Lord"^[215].

The text he left that day is a meditation on the glory promised to our bodies: "On the summit of Tabor, Christ unveils for a few instants the splendour of his divinity, and shows himself to the chosen witnesses as he truly is: the Son of God"^[216].

Twenty-eight years later, on 6 August 2006, the feast again fell on a Sunday. At the Angelus of Castel Gandolfo, Benedict XVI presented the Transfiguration as "an anticipation of the paschal mystery": "On the transfigured face of Jesus shines a ray of the divine light which he kept deep within him. That same light will shine on the face of Christ on the day of the Resurrection"^[217]. Then he recalled "that other analogous Sunday" when the pilgrims had been unable to pray with Paul VI, who, "on the evening of that 6 August 1978, fell asleep in the Lord"^[218].

Lisbon, 6 August 2023: "to shine, to listen, not to fear"

On 6 August 2023, the feast coincided with the closing Mass of World Youth Day, in Lisbon's Tejo Park^[219]. Pope Francis took Peter's word, "Lord, it is good that we are here!", and offered young people three verbs to take away: "to shine, to listen, not to fear"^[220]. The light of Tabor, he explained, was for the apostles a "bath of light" preparing them "for the night of the Passion"^[221].

"We shine when, welcoming Jesus, we learn to love as he does. [...] Everything is there: everything there is to do in life lies in this word: listen to him." — Pope Francis, homily of the World Youth Day Mass, Lisbon, 6 August 2023^[222]

The third verb took up Jesus' last word on the mountain: "Rise, and have no fear" (Mt 17:7). Francis asked the young people to repeat it silently in their hearts: "Have no fear"^[223].

Leo XIV: the humble glory of Tabor

Pope Leo XIV commented on the Transfiguration at the Angelus of the Second Sunday of Lent, 1 March 2026, presenting it as an icon full of light^[224]. He stressed the discretion of that glory: a humble glory, entrusted to Peter, James and John alone, not as a spectacle offered to crowds, but as a mark of confidence given to those three witnesses^[225].

In that meditation, the pope reread the Transfiguration in the light of Easter: the paschal light, made of death and resurrection, of darkness crossed and of newness, reaches according to him bodies wounded by violence, bodies crucified by pain and bodies abandoned in misery; thus, he explained, does the Redeemer transfigure the wounds of history^[226].

The pope concluded on the patience this mystery requires: understanding what the disciples had seen takes time, a time of silence to listen to the Word and a time of conversion to taste the Lord's company, and he entrusted that journey to Mary, invoked as Morning Star^[227].

From the Fathers to the mystics of the 20th century, the mountain of the Transfiguration has nourished the prayer of the saints. All hear the same lesson in it: the glory glimpsed is not an escape, but a strength to follow Christ to the Cross, and a promise for afterwards.

Saint Augustine: "Life comes down to be killed"

Saint Augustine pauses over Peter's desire to pitch tents and stay on the mountain. The Catechism has kept his commentary, drawn from one of his sermons, because it says in few words why one does not remain on Tabor:

"This Peter had not yet understood when he desired to live with Christ on the mountain. He has reserved that for you, Peter, for after death. But now he himself says: Go down to labour on earth, to serve on earth, to be despised, crucified on earth. Life comes down to be killed; the Bread comes down to hunger; the Way comes down to grow weary on the way; the Source comes down to thirst; and you refuse to labour?" — Saint Augustine, sermon 78, 6, quoted by the Catechism of the Catholic Church, no. 556^[228]

The joy of Tabor is not refused to Peter: it is reserved for him. Christ himself comes down from the mountain to go to the Cross, and the disciple learns to come down with him.

Saint Thérèse of Lisieux: the Holy Face, 6 August 1896

At the Carmel of Lisieux, the feast of the Transfiguration had a special relief: the confraternity of the Holy Face, spread from Tours, made it one of its great feasts, and Louis Martin had been enrolled in it with four of his daughters on 26 April 1885^[229]. In 1896, three sisters of the novitiate bore the name of the Holy Face: Thérèse of the Child Jesus and of the Holy Face, her sister Céline, become Sister Geneviève, and Sister Mary of the Trinity^[230]. For the feast of 6 August 1896, Thérèse proposed that they consecrate themselves together to the Holy Face and wrote a prayer for them, which the three religious signed in red ink; an illuminated image accompanied it, with their photographs in medallion beneath a reproduction of the Holy Face of Tours^[231].

The contrast chosen by Thérèse is striking. On the day when the Church contemplates the face of Christ "shining like the sun", she consecrates herself to his veiled and humiliated Face of the Passion, awaiting the day when that same face will show itself in its glory:

"O beloved Face of Jesus! while awaiting the eternal day when we shall contemplate your infinite Glory, our sole desire is to charm your Divine Eyes by hiding our face also, so that here below no one may recognise us... your Veiled Gaze, that is our Heaven, O Jesus!" — Saint Thérèse of the Child Jesus and of the Holy Face, consecration to the Holy Face, 6 August 1896^[232]

At the head of the prayer, Thérèse had copied a sentence of Saint John of the Cross: "The smallest movement of pure Love is more useful to the Church than all other works together", so that souls "may arrive promptly at seeing Jesus, Face to Face"^[233][234]. Tabor is for her a promise: to see one day without veil the face one loves today hidden.

Saint Faustina: "not only on Tabor, but also on Calvary"

Saint Faustina Kowalska, canonised in 2000, takes up the image of Tabor in two passages of her Diary. In a dialogue between the God of mercy and the soul aspiring to perfection, the soul answers the Lord's call with an offering without reserve^[235]:

"Sustained by your grace, I am ready to follow you, Lord, not only to Tabor, but also to Calvary." — Saint Faustina, Diary, § 1487^[236]

Further on in the same diary, she rereads her whole journey in the light of the stages of Christ's life: "My Jesus, now I see that I have passed through all the stages of life in following you: childhood, youth, vocation, apostolic labours, Tabor, the Garden of Olives, and now I am already with you on Calvary"^[237]. Tabor is there a real stage, a time of light given for the road, between the apostolic labours and the Garden of Olives.

Gabrielle Bossis: "It is also Love that transfigured Me"

Gabrielle Bossis (1874-1950), a laywoman born in Nantes, nurse at Verdun then author of sketches, noted for fifteen years the words she inwardly heard from Christ; the first volume of He and I appeared in her lifetime, in 1948^[238]. Three of her notes bear the date of 6 August. In 1939, at the high Mass of the feast, Jesus reminds her of her childhood prayer, "Transfigure yourself for my soul, Lord", and asks her: "Have I not done it in my Goodness for you?"^[239]. In 1942, he invites her to look toward him more often: "Multiply your glances toward Me, contemplate more often by loving more. You will see Me under new and infinite aspects"^[240].

The note of 6 August 1948 gives the key to the feast, as Gabrielle Bossis received it:

"Do you remember, when you were little, you said to Me: 'Transfigure yourself, transfigure yourself before my eyes, Lord!' You trusted Me. You withdrew to the mountain of solitude and you heard My Voice. Then, you saw Me in another light. It is also Love that transfigured Me before My Apostles. See, always Love, at the source of what comes from God." — Gabrielle Bossis, He and I, 6 August 1948^[241]

Without having the authority of a teaching of the Church, this page says with simplicity what the feast celebrates: the Transfiguration is a gift of love, made by Christ to his friends so that they may recognise him, and which God renews for those who seek him in the solitude of prayer.

The Book of Heaven: the "transfigured" soul

The Servant of God Luisa Piccarreta (1865-1947), a laywoman of Corato in Apulia, left in the Book of Heaven the account of what Jesus taught her about living in the Divine Will. That gift is not only doing what God wills: it is letting the divine Will itself live and act in the soul, in place of one's own will, like a sun that rises and illumines everything^[242]. A page of 22 March 1927 uses precisely the image of the light that transfigures:

"My daughter, when the sun rises, it drives away the darkness and makes the light appear. [...] In the same way, when my Will rises, all human acts are clothed with Light. They come to take their place of Honour in my Will. Each of them takes on a distinct beauty and the brilliance of the divine Colours, so that the soul remains transfigured and covered with an indescribable beauty." — Jesus to Luisa Piccarreta, The Book of Heaven, volume 21, 22 March 1927^[243]

What follows on that page announces what this interior sun works in trials: "If my Will rises, it drives away the night of the human will, it drives away all fears", and it clothes even tears with its light^[244]. Brought together with the feast, this private revelation prolongs what the liturgy promises: the light of Tabor is not reserved for a summit in Galilee; God wills to make it rise in the soul that lets itself be inhabited by his Will.

The feast of 6 August raises a few questions, from historians as from believers of other traditions. The four most frequent concern its origin, its relations with a pagan feast, the reality of the event, and the way East and West understand its light. Each is set out here in its strongest form, then given its answer.

Objection 1 — "A feast born of a military victory"

The objection. The universal feast of the Transfiguration was instituted by a crusading pope, to commemorate a battle against the Ottomans. A feast of Christ should not celebrate the defeat of an adversary; it would bear the mark of the age of the crusades.

Answer. The feast was not born at Belgrade. It was celebrated in Jerusalem in the 7th century, inscribed in Byzantine books at the beginning of the 8th, adopted by many dioceses of the West in the 10th century, and the Gospel of the Transfiguration had been read in Rome at the beginning of Lent since Saint Leo the Great^{[245][246][247]}. Callixtus III did not create the feast: he extended it to the whole Church, on the date most Churches already gave it^[248].

The very text of the 1457 bull shows the order of reasons. Before speaking of Belgrade, it sets out at length the mystery: the divinity and humanity of Christ manifested in one person, the Passion freely accepted, the testimony of the Law and the Prophets, the whole Trinity, the glory promised to the body^[249][250]. The victory is presented in it as a deliverance obtained through the prayer of all Christendom, after the midday bells and the processions requested the previous year, and the pope compares it to the Passover of the Hebrew people delivered from Egypt^[251][252]. Giving thanks to God for the deliverance of a besieged city is not celebrating the death of its enemies, and the bull ends besides with a request for peace: that God, once the fear of enemies is set aside, grant "that peace which the world cannot give" and tranquil times^[253].

Finally, the present liturgy keeps no trace of the battle: the collect, the preface and the readings speak only of Christ, of his glory and of our adoption^[254][255]. What the Church celebrates on 6 August is a mystery of Christ's life; Belgrade explains only why that mystery received a day in the whole Latin calendar.

Objection 2 — "Vardavar: a christianised pagan feast"

The objection. In Armenia, the Transfiguration bears the name of Vardavar, that of an ancient pagan feast of roses it replaced. The feast would therefore be only a nature cult covered with a Christian veneer.

Answer. The connection with a pagan feast concerns only the Armenian form of the celebration, and Holweck noted that the feast is still missing from the two ancient Armenian calendars he knew^[256]. In Jerusalem, Constantinople and Rome, the feast has no pagan antecedent: it comes directly from the Gospel, where the event is recounted by three evangelists and attested by one of the witnesses, Saint Peter (2 Pet 1:16-18)^{[257][258][259]}.

Where the Armenian Church replaced an older feast, it changed its meaning. Bishop Gregory Archarouni, around 690, explains that the name of the feast of roses was kept "because Christ opened his glory like a rose on Mount Tabor"^[260]. The name remains, but what it designates is no longer a force of nature: it is the glory of a person, Jesus of Nazareth, seen by men who bore witness to it. To give an ancient day a new content is to evangelise it, not to let oneself be absorbed by it.

Objection 3 — "A symbolic account, a vision without reality"

The objection. The Transfiguration would be only an interior vision or a theological scene: the mountain, the cloud, Moses and Elijah would be symbols borrowed from the Old Testament. Saint Thomas himself reports a gloss of Saint Bede speaking of a glorification of the body shown "in an imaginary representation of future blessedness"^[261]. The feast would then celebrate an image, not a fact.

Answer. Saint Thomas answers that gloss: if one speaks of image, "it is not that this brightness was not a true brightness of glory", but because it represented in advance the perfection of the glory that will belong to the risen body^[262]. The word "image" designates what the brightness announced, not its unreality; Thomas adds that the radiance of Christ's body was a miracle, like his walking on the waters^[263].

The witnesses themselves set aside the symbolic reading in advance. Saint Peter's second letter, read at the Mass of 6 August, affirms: "it was not by resorting to cleverly devised myths that we made known to you the power and coming of our Lord Jesus Christ, but because we were eyewitnesses of his majesty" (2 Pet 1:16)^[264]. Saint Luke notes that the apostles were heavy with sleep, "but staying awake, they saw the glory of Jesus" (Lk 9:32), and the three evangelists locate the episode in relation to precise words, "six days" or "about eight days" after Peter's profession of faith^[265][266]. The Catechism ranks it among the events of Christ's public life, on the same footing as his baptism^[267].

The presence of Moses and Elijah is not a literary invention: it is the sign, Saint Leo says, that "the writings of the one and the other Covenant guarantee each other"^[268]. The detailed study of the account, of its details and of the readings proposed of it, is found in the article The Transfiguration.

Objection 4 — "Created or uncreated light: East and West contradict each other"

The objection. In the 14th century, the light of Tabor was the object of a great debate in the Byzantine Church. Against the monk Barlaam, Gregory Palamas, Archbishop of Thessalonica, taught that this light was not a created phenomenon, but a real manifestation of divinity, an uncreated divine "energy", distinct from the essence of God, which remains inaccessible; the synods of Constantinople of 1341 and 1351 proved him right, and another synod proclaimed him in 1368 Father and Doctor of the Church^[269]. Saint Thomas, for his part, speaks of a brightness passing into Christ's body "as when the air is illumined by the sun"^[270]. On the same day, the two Churches would therefore celebrate two different things, and the feast would divide Christians more than it unites them.

Answer. On the fact, the two traditions say the same thing: what the apostles saw is the divine glory of the Son. Saint Thomas speaks of the brightness "of glory", which derives "from the divinity" of Christ, according to Saint John Damascene; the Catechism says Jesus shows "his divine glory"; the Byzantine kontakion, which it quotes, sings Christ "truly the radiance of the Father"^[271][272]. The difference bears on the theological explanation: Palamas really distinguishes in God essence and energies, a distinction Latin theology has not received, whereas Thomas attends to the manner in which that glory made itself visible in a still mortal body^[273][274].

That difference of schools has never prevented the Catholic Church from praying with the words of the East. The Catechism makes the kontakion of the feast its own^[275]. In his letter Orientale Lumen on the Eastern Churches, Saint John Paul II admiringly presents their doctrine of divinisation: "through the power of the Spirit dwelling in man, deification already begins on earth, the creature is transfigured and the Kingdom of God is inaugurated"; and he sees on Tabor "that man transformed by love", "the man we are all called to be"^[276]. On the Second Sunday of Lent, the Latin Church reads each year the Gospel of the Transfiguration, while the Orthodox Church, which venerates Palamas as a saint, commemorates the theologian of its light: on that day, East and West look at the same mountain^[277][278]. The question of uncreated light is set out more fully in the article Gregory Palamas, and the relations between the Catholic Church and the Orthodox in What does the Church say about the Orthodox?.
