Holy Mary, Mother of God (1 January)

Name and liturgical rank

The official title of the feast in the present Roman Missal is In octava Nativitatis Domini, sollemnitas sanctae Dei Genetricis Mariae — "on the octave of the Nativity of the Lord, the solemnity of Holy Mary, Mother of God" (Ignispedia translation)^[6]. Like Christmas and Easter, it holds in the hierarchy of Catholic celebrations the highest rank, that of solemnity^[7], which determines a complete proper liturgy: collect, preface, Gloria and Creed sung, and precedence over any other event of the calendar that might fall on the same day.

Place in the Christmas octave

1 January is the eighth and last day of the Christmas octave, that liturgical prolongation of eight days by which the Church celebrates the Nativity of the Lord as one single long feast day^[8]. The place of Christmas in the liturgical year, its proper liturgy of the three Masses and the tradition of the crib are developed in their own right in the article Christmas (25 December); the present article retains only what directly sheds light on 1 January. This octave is itself part of Christmastide, which extends beyond 1 January to the feast of the Baptism of the Lord, by way of Epiphany on 6 January^[9].

A holy day of obligation

Canon 1246 § 1 of the 1983 Code of Canon Law explicitly names the solemnity of Mary, Mother of God among the days of precept of the universal Church, alongside Sunday, Christmas, Epiphany, the Ascension and Corpus Christi:

"Sunday, on which by apostolic tradition the paschal mystery is celebrated, must be observed in the universal Church as the primordial holy day of obligation. The following days must also be observed: the Nativity of our Lord Jesus Christ, the Epiphany, the Ascension, the Body and Blood of Christ, Holy Mary the Mother of God, her Immaculate Conception, her Assumption, Saint Joseph, Saint Peter and Saint Paul the Apostles, and All Saints." — Code of Canon Law (1983), canon 1246 § 1^[10]

The canon thus carefully distinguishes three Marian holy days of obligation — the Mother of God (1 January), the Immaculate Conception (8 December) and the Assumption (15 August) — without confusing them. The following paragraph of the same canon leaves to the conferences of bishops, with the agreement of the Holy See, the faculty of suppressing certain holy days of obligation or transferring them to the nearest Sunday^[11]; in France, the Conference of Bishops has maintained the status quo in force since 1802: only four solemnities — Christmas, the Ascension, the Assumption and All Saints — remain holy days of obligation there, so that 1 January, while remaining of obligation in universal law, is not so in French particular law^[12].

The testimony of the Gelasian Sacramentary

The oldest Roman liturgical book documenting a celebration on 1 January, the Gelasian Sacramentary (8th century, but reflecting an earlier usage), does not yet speak of "Circumcision": it entitles the day In Octabas Domini, "on the octave of the Lord"^[13]. Its proper collect asks that the faithful be strengthened by the eternal divinity of him by whose mystery, in the flesh, they have been restored:

"O God, who grant us to celebrate the eighth day of the Saviour's birth, strengthen us by the eternal divinity of him by whose commerce in the flesh we have been restored." (Ignispedia translation) — Gelasian Sacramentary (8th c.), collect of 1 January^[14]

The Gelasian preface of this day explicitly evokes "circumcision and uncircumcision" as figures of the Jewish and Gentile peoples gathered into the salvation of Christ, and the oldest lectionaries associate with this date the account of Luke 2:21-32, which brings together in a single passage the circumcision of the Child (verse 21) and his presentation in the Temple (verses 22-32)^[15]. It is this composite reading, more than circumcision alone, which explains why the ancient Roman title remains neutral: "octave of the Lord", and not "feast of the Circumcision".

The Marian stational Mass of Saint Mary in Trastevere

The Benedictine liturgist Ildefonso Schuster, Cardinal Archbishop of Milan and a great connoisseur of the ancient Roman sanctoral, shows that the Marian character of 1 January is bound up with the very place of the Roman liturgical station: since the Mass of the day was celebrated in a Marian basilica, a special commemoration of Mary's virginal motherhood was inserted there, even before the title of Circumcision, of Gallic origin, was added to that of octave of the Lord^[16]. A Mass in honour of Mary was sometimes said there on that day, although the official title of the day in the liturgical books did not change before the reforms of the 20th century^[17]. The primitive station of this day remains unknown: the Würzburg Lectionary indicates Saint Mary of the Martyrs, at the Pantheon, and it was only after Pope Gregory IV (827–844) had a crib installed there that the station was transferred to Saint Mary in Trastevere (S. Maria trans Tiberim)^[18]. It is this ancient Marian stratum, prior to the importation of the theme of the Circumcision, which allows historians of the liturgy to speak of "restoration" rather than invention when Paul VI makes 1 January, in 1969, an explicitly Marian solemnity^[19].

The struggle against the pagan Kalends

1 January inherited, in the Roman world, the memory of the Kalends of January, the civil feast of the New Year marked by profane rejoicings — banquets, exchanges of gifts, disguises — which the bishops of the 5th and 6th centuries judged incompatible with the Christian spirit^[20]. Far from simply christianizing this feast, the Latin Church first sought to correct its excesses by fasting and penance, before a liturgical alternative centred on the circumcision of Jesus imposed itself in Gaul.

The Council of Tours (567)

It is in Gaul, and not in Rome, that the feast explicitly centred on the circumcision of the Christ Child was born. The second provincial council of Tours, assembled in 567, prescribes a proper Mass of the Circumcision for 1 January, in order to counter the resurgences of the pagan Kalends^[21]. The same canon (XVIII, XVII in the old numbering), devoted to monastic fasts, organizes the fast of the whole month of December until the 25th and prescribes, at the kalends of January, penitential litanies "to trample underfoot the custom of the pagans"^[22]. It is the oldest and most explicit ecclesiastical testimony to a feast of the Circumcision as such, nearly a century earlier than any comparable mention at Rome.

Spread in Spain and Frankish Gaul

Saint Isidore of Seville, in his Regula Monachorum (chapter X, "On feasts"), already mentions the "holy season" running "from the day of the Nativity of the Lord to the day of his Circumcision", proof that the Spanish usage of thus designating 1 January predates his death in 636^[23]. The Lectionary of Victor of Capua, compiled in the 540s, is identified by historians of the liturgy as the oldest written attestation of the very title of "feast of the Circumcision"^[24]. From Gaul and Spain, this usage then spread to the Frankish empire, before reaching Rome itself in the course of the Middle Ages, the Eternal City being traditionally more conservative in adopting liturgical titles from elsewhere^[25].

The medieval Roman title: a twofold face

When Rome finally adopted, in the course of the Middle Ages, an explicit designation for 1 January, it did not choose purely and simply to erase the ancient Marian memory: the medieval Roman Missal, down to the reform of 1969, bears the composite title In Circumcisione Domini et Octava Nativitatis — "on the Circumcision of the Lord and the octave of the Nativity" (Ignispedia translation)^[26]. The offices of this day, in the Tridentine breviary, continue to give the Virgin Mary a far from negligible place, though without devoting to her the principal title of the feast. It is this balance, shifted towards the Circumcision and judged insufficiently faithful to the oldest Roman usage, which the liturgical reform of the 20th century would progressively rectify.

Pius XI and the 1500th anniversary of the Council of Ephesus

In 1931, to commemorate the fifteen-hundredth anniversary of the Council of Ephesus (431) — the council which had defined against Nestorius that Mary may legitimately be called Theotokos^[27] — Pope Pius XI published the encyclical Lux Veritatis, dated 25 December 1931^[28]. In it he ordered the publication of a proper Office and Mass of the Divine Maternity of Mary, to be celebrated by the universal Church — the date of 11 October being fixed by the implementing decree of 6 January 1932^[29]:

"We have ordered our Supreme Congregation presiding over the Sacred Rites to publish an Office and a Mass of the Divine Maternity, which must be celebrated by the universal Church." (Ignispedia translation) — Pope Pius XI, encyclical Lux Veritatis, 25 December 1931^[30]

The pope justifies this choice by the concern to offer Marian piety a lasting "liturgical monument", capable also, he hopes, of fostering the reunion of the separated Christians of the East, particularly attached to the veneration of the Theotokos^[31]. He also had restored, at his own expense, the 5th-century Marian mosaics of the Basilica of Saint Mary Major, then degraded by time, as a concrete gesture accompanying the institution of the new feast^[32].

A theologically redundant doublet

For nearly forty years, the Latin Church thus celebrated the divine motherhood of Mary on two distinct dates: 11 October (the feast instituted by Pius XI, devoted exclusively to this truth) and 1 January (still officially dedicated, in its title, to the Circumcision of the Lord). This situation, which was not without pastoral logic at the time of its institution, became one of the points which the conciliar liturgical reform judged fit to simplify: rather than maintaining two distinct feasts bearing, at bottom, on the same doctrinal truth, the reformers of the calendar chose to merge the intention of 11 October into the feast of 1 January, restoring to the latter its oldest Marian title.

The 1960 simplification

A first, less noticed step precedes the great conciliar reform: the Code of Rubrics promulgated by Pope John XXIII in 1960 simplifies the title of 1 January by soberly designating it as the "Octave of the Nativity", without further explicit mention of the Circumcision in the official title of the day, even though the proper Gospel of the Mass (Luke 2:21) continues to bear on that episode^[33].

Mysterii Paschalis (14 February 1969)

The decisive reform comes from Pope Paul VI, who approves by the motu proprio Mysterii Paschalis, dated 14 February 1969, a new General Roman Calendar intended to "bring the paschal mystery into clearer light" throughout the liturgical year (Ignispedia translation)^[34]. The text fixes the entry into force of the new calendar on 1 January 1970^[35]. The Universal Norms for the Liturgical Year and the Calendar, promulgated on 21 March 1969 in application of this motu proprio, state explicitly, in their list of the principal solemnities of the Lord and of the Virgin Mary:

"1 January, the octave day of the Nativity of the Lord, is the solemnity of Mary, the Holy Mother of God, and also the commemoration of the conferral of the Most Holy Name of Jesus." — Universal Norms for the Liturgical Year and the Calendar (1969), no. 35, f)^[36]

This text accomplishes three things at once: it restores the Marian title which Rome had known before the late adoption of the Gallic term of Circumcision; it retains the memory of the imposition of the name of Jesus, related by the same verse of Luke (2:21) which formerly grounded the feast of the Circumcision, but relegating it to the rank of a secondary commemoration rather than the principal title; and it absorbs the intention of the feast of the Divine Maternity of 11 October instituted by Pius XI, henceforth suppressed from the universal calendar as a distinct feast.

Why a restoration rather than an innovation

The liturgists who worked on the conciliar reform insisted that the new title of 1 January was not a modern invention but a return to the sources: the Gelasian Sacramentary, the station of Saint Mary in Trastevere and the absence, in the oldest Roman books, of a title centred on circumcision alone, showed that the Marian foundation of this day was earlier, in Rome itself, than the Gallic importation of the theme of the Circumcision^[37]. The 1969 reform therefore does not make an ancient content disappear in favour of a new one: it chooses, between two genuinely attested Roman traditions — the very ancient one of the Marian octave, and the later one, of Gallic origin, of the Circumcision — to give priority of title to the first, while retaining the second as the commemoration of the Holy Name of Jesus in the Liturgy of the Word.

The proper readings of the Mass

The present Roman Missal assigns to the Mass of 1 January three readings whose thematic unity sheds light on the meaning of the feast: the priestly blessing of Aaron, the sending of the Son of God "born of a woman", and the welcome of the Child by the shepherds beside his Mother.

The first reading retains the famous blessing entrusted by God to Moses for Aaron:

"The Lord bless thee, and keep thee. The Lord shew his face to thee, and have mercy on thee. The Lord turn his countenance to thee, and give thee peace." — Book of Numbers 6:24-26^[38]

The choice of this text for the opening of the civil year is no accident: it makes resound, on the first day of the calendar, a prayer of blessing and peace, directly preparing the theme of the World Day of Peace instituted by Paul VI. The second reading, taken from the Epistle to the Galatians, explicitly links the motherhood of Mary to the work of salvation:

"But when the fulness of the time was come, God sent his Son, made of a woman, made under the law: that he might redeem them who were under the law: that we might receive the adoption of sons. And because you are sons, God hath sent the Spirit of his Son into your hearts, crying: Abba, Father. Therefore now he is not a servant, but a son. And if a son, an heir also through God." — Epistle of Saint Paul to the Galatians 4:4-7^[39]

The proper Gospel, lastly, relates the visit of the shepherds to the Holy Family and concludes with the imposition of the name of Jesus, eight days after his birth, in accordance with the Mosaic law of circumcision:

"And after eight days were accomplished, that the child should be circumcised, his name was called JESUS, which was called by the angel, before he was conceived in the womb." — Gospel according to Saint Luke 2:21^[40]

This single verse alone carries the memory of the old title of "Circumcision of the Lord" and that of the "Most Holy Name of Jesus" evoked by the Universal Norms of 1969^[41]: nothing of the ancient scriptural content is lost in the reform; only the principal title of the day has changed its centre of gravity.

The collect and the liturgical colour

Mass is celebrated in white, the colour of the solemnities of the Lord and of Marian feasts^[42]. Its collect takes up the ancient Marian prayer already in use in the Missal of Saint Pius V — distinct from the 8th-century Gelasian collect quoted above, which was Christological^[43]:

"O God, who through the fruitful virginity of Blessed Mary bestowed on the human race the grace of eternal salvation, grant, we pray, that we may experience the intercession of her, through whom we were found worthy to receive the author of life, our Lord Jesus Christ, your Son." — Roman Missal, collect of 1 January^[44]

Instituted by Paul VI (8 December 1967)

On 8 December 1967, the feast of the Immaculate Conception, Pope Paul VI announced the institution of a World Day of Peace, fixed each year on 1 January, "at the opening of the calendar which measures and describes the path of human life in time" (Ignispedia translation)^[45]. The first message, published for 1 January 1968, makes explicit the meaning of this choice of date and the universal ambition of the appeal:

"We must always speak of peace. The world must be educated to love peace, to build it, to defend it." (Ignispedia translation) — Pope Paul VI, first message for the World Day of Peace, 1 January 1968^[46]

Paul VI takes care from the outset to distinguish his conception of peace from any soft or naive pacifism, grounding it in justice and respect for the fundamental rights of the person:

"The word peace does not mean pacifism; it does not conceal a weak and lazy conception of life; on the contrary, it proclaims the highest and most universal values." (Ignispedia translation) — Pope Paul VI, first message for the World Day of Peace, 1 January 1968^[47]

A curious chronological priority

A chronological detail deserves notice: the first World Day of Peace, celebrated on 1 January 1968, preceded by two years the entry into force of the new Roman calendar which officially makes that same day the solemnity of the Mother of God (1 January 1970)^[48]. At the time of its institution, the Day of Peace therefore fell, liturgically, on a day still entitled "Octave of the Nativity" according to the simplified 1960 calendar, without yet officially bearing the restored Marian title. The two initiatives — the liturgical restoration of the Marian title and the institution of the Day of Peace — nevertheless proceed from a single pastoral intuition of Paul VI on what the first day of the year must be for a Christian: a day of blessing, of peace and of praise to the motherhood of Mary, rather than a mere profane continuation of the New Year rejoicings.

Continuity under Paul VI's successors

Each pope since Paul VI has maintained the tradition of a message for the World Day of Peace, published at the end of the preceding year and read or commented on the following 1 January: Saint John Paul II, Benedict XVI, Francis and Leo XIV have each chosen a distinct annual theme, ranging from the dignity of the human person to integral development, from integral ecology to universal fraternity^[49]. This pontifical continuity makes 1 January one of the rare days on which the Church addresses each year a doctrinal and social message explicitly destined, beyond Catholics alone, to "all men of good will"^[50].

The Te Deum of 31 December and the Veni Creator of 1 January

Catholic piety traditionally associates with this octave two ancient Latin hymns, sung in thanksgiving for the year gone by and in invocation for the year beginning. On the evening of 31 December, many parishes and above all Saint Peter's Basilica in Rome have the Te Deum, a hymn of praise going back to the first Christian centuries, sung as a public prayer of gratitude for the benefits received during the year drawing to a close^[51]. On 1 January, this thanksgiving continues with the singing of the Veni Creator Spiritus, an invocation to the Holy Spirit for the new year. The Church attaches to the public recitation of these two hymns, on 31 December and 1 January respectively, a plenary indulgence under the usual conditions, according to concession no. 26 of the Enchiridion Indulgentiarum^[52].

A holy day whose pastoral status varies

Because 1 January coincides with the civil New Year, a public holiday in almost every country, the question of the obligation to attend Mass arises there in a particular way: canon 1246 § 2 of the Code of Canon Law allows conferences of bishops, with the agreement of the Holy See, to transfer certain solemnities to the nearest Sunday or to dispense the faithful from them in determined circumstances^[53]. The effective discipline thus varies from one country to another and belongs, in the last resort, to the local conference of bishops and the ordinary of the place; the universal principle of the law, for its part, remains unchanged: in universal law, 1 January remains a holy day of obligation on the same footing as Christmas or Epiphany, even where particular law has lifted the obligation, as in France^[54].
