For nearly twenty centuries, a single voice has echoed through the Desert Fathers, the doctors, the mystics, and the popes: one must receive often, and if possible every day, the Body of Christ. From the earliest communities of Carthage and Caesarea to the decree of Saint Pius X in 1905, the saints have continually urged the faithful toward the Eucharistic table, opposing both lukewarmness and scrupulous rigorism. This article gathers their strongest words — their own voice — on frequent communion.
This is not an exposition once again of what the Eucharist is, nor how to receive worthily: these questions are addressed in How to Grow in Frequent Communion (the Pius X turning point, the two conditions, the fruits of the sacrament according to the Catechism) and in The Real Eucharistic Presence (the doctrine). The present anthology focuses on what the saints said about it, because their formulas — brief, striking like maxims — convey the message better than a long treatise.
Three complementary registers can be heard here: the urgent call to commune often, as naturally as breathing; the requirement to approach worthily, with a pure heart; and the wonder at the fruits of union, strength, and eternal life that communion pours into the soul. Far from contradicting each other, these three tones compose the great symphony of the saints on the “daily bread.”
Why Did the Saints Call for Frequent Communion?
“Whoever eats my flesh has eternal life”
The entire call of the saints to frequent communion stems from a word of Christ, in the discourse on the bread of life at Capernaum:
“Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day. […] Whoever eats my flesh and drinks my blood remains in me, and I in him.”
— Jesus, Gospel according to Saint John 6:54-56[1]
The Fathers understood this promise in the present tense: eternal life does not begin only after death, it is already received in communion. Hence their constant reasoning: if eating this Bread “is to have life,” then communing often is to live more fully. Saint Basil expresses it as self-evident: “Who doubts that to share frequently in life is to have life in abundance?”[2].
“Give us this day our daily bread”
Another great source of the patristic call is the fourth petition of the Our Father. Very early, the Fathers read the “bread of this day” (Mt 6:11) not only as food for the body but as the Eucharistic Bread that the Christian asks to receive each day. The Greek word epiousios — rare, almost untranslatable, rendered as “supersubstantial” in Saint Jerome’s Vulgate — nourished this spiritual reading: the bread “above all substance” that is the Body of Christ[3].
This Eucharistic interpretation of the Our Father is one of the oldest and most universal arguments in favor of frequent communion: Christ himself would have taught us to ask for this Bread “each day.”
The Church’s desire: to commune at every Mass
This call of the saints is not a private devotion: it aligns with the official desire of the Church. The Council of Trent, defining Eucharistic doctrine in response to the Reformation, expresses the wish that the faithful not only attend Mass but actually receive communion:
“The holy council desires that at every Mass the faithful present should commune not only by spiritual desire but also by sacramental reception of the Eucharist.”
— Council of Trent, 22nd session (1562), Doctrine on the Sacrifice of the Mass, ch. 6[4]
The saints thus only amplified a desire already held by the Church itself: that the Lord’s table, set at every Mass, be truly a table at which one eats, and not merely an altar to be looked upon.
The Voice of the Church Fathers
No era spoke of frequent communion more naturally than the early Church, where receiving the Eucharist daily, or several times a week, was taken for granted. The great patristic voices all say the same thing, each with its own emphasis.
Saint Cyprian: Receiving the Bread of Salvation Every Day
Saint Cyprian of Carthage (c. 200–258), bishop and martyr, comments on the petition for the “bread of this day” in his treatise On the Lord’s Prayer (252). For him, this bread is Christ Himself, and the stakes are serious: depriving oneself of communion risks being separated from the Body of Christ.
“Christ is the bread of life, and this bread is not for everyone, but it is ours. […] We ask that this bread be given to us each day, so that we who are in Christ, and who receive the Eucharist daily as the food of salvation, may not be separated from the body of Christ by the interposition of some graver fault.”
— Saint Cyprian of Carthage, De oratione dominica, 18[5]
In times of persecution, this daily communion was also a weapon: Cyprian recommends strengthening the faithful through the Eucharist so that they may be ready for martyrdom. Frequent communion, for him, is not an easy consolation but the bread of warriors.
Saint Ambrose: “Why Do You Receive It Only Once a Year?”
Saint Ambrose of Milan (c. 340–397), in his treatise On the Sacraments (De sacramentis), expresses pastoral surprise that Christians, calling the Eucharist their “daily bread,” nevertheless receive it only once a year:
“If it is daily bread, why do you take it after a year? […] Receive each day what benefits you each day. Live in such a way that you deserve to receive it every day. He who does not deserve to receive it every day does not deserve to receive it once a year.”
— Saint Ambrose of Milan, De sacramentis, Book V, ch. 4[6]
The argument is irrefutable and will be echoed by all defenders of frequent communion: if one dares to call this Bread “daily,” logic demands receiving it often. For Ambrose, infrequent communion is not a sign of respect—it is a contradiction.
Saint Basil: “We Commune Four Times a Week”
At the other end of the Empire, Saint Basil the Great (c. 330–379), bishop of Caesarea, responds to a noblewoman who asks him about the frequency of communion. His answer is a valuable piece of realism for the historian, as it describes a lived practice:
“To commune every day, and to partake of the holy body and blood of Christ, is good and profitable […]. We ourselves commune four times a week: on the Lord’s Day, Wednesday, Friday, and Saturday, and on other days if there is the commemoration of a saint.”
— Saint Basil the Great, Letter 93 to Caesaria the Patrician[7]
Basil testifies to a time when frequent communion, far from being a distant ideal, was the shared norm among devout laity. His letter would become, centuries later, one of the favored supports of Saint Pius X.
Saint Augustine: Receiving Every Day, or Abstaining Out of Reverence
Saint Augustine (354–430) introduces a nuance destined for great influence. Asked by Januarius about the frequency of communion, he refuses to decide abstractly: customs vary, and each may honor the Lord in their own way, provided it is out of love.
“Some receive the body and blood of the Lord every day; others receive it on appointed days. […] He who does not dare to receive it every day and he who does not dare to omit any day are both moved by the desire to honor Him.”
— Saint Augustine, Letter 54 to Januarius, ch. 2–3[8]
But this freedom left to devotion is not indifference. The famous phrase “Live so that you deserve to receive it every day” is not from Augustine: it is from Saint Ambrose (De sacramentis, V, 4, 25 — quoted above), and it is this phrase that Saint Thomas took up[9]. The Augustinian nuance is therefore subtle: frequent communion is a great good, but reverence can sometimes counsel abstinence—without that abstinence ever becoming contempt or neglect.
Saint John Chrysostom: Neither Often Nor Rarely, but with a Pure Heart
Saint John Chrysostom (c. 349–407), the “Golden Mouth,” balances enthusiasm with a demand for purity. Against those who commune out of routine and those who stay away out of lukewarmness, he shifts the question: what matters is not primarily the number of communions, but the state of the soul approaching.
“It is neither those who commune once, nor those who commune often, nor those who commune rarely, but those who do so with a pure conscience, a pure heart, and an irreproachable life. Let those approach continually; but those who are not such, not even once.”
— Saint John Chrysostom, Homily 17 on the Epistle to the Hebrews[10]
Chrysostom does not oppose frequency and dignity: he subordinates one to the other. Well prepared, one should commune “continually”; poorly prepared, one should “not even once.” This warning, far from discouraging frequent communion, sets its true condition—the one the saints will repeat down to our day.
The Voice of the Doctors: Saint Thomas Aquinas
Daily Communion, “Praiseworthy” for the Well-Disposed
The common doctor, Saint Thomas Aquinas (1225–1274), gives the question its theological foundation. In the Summa Theologica, he asks “whether it is permitted to receive this sacrament every day,” and his answer is clear: considered from the side of the sacrament itself, whose fruit is union with God and growth in charity, daily communion is not only permitted but praiseworthy. He adopts the logic of Saint Ambrose:
“Since, whenever the blood of Christ is shed, it is for the remission of sins, I must always receive it, I who always sin; I must always keep the remedy.”
— Saint Ambrose, cited with approval by Saint Thomas Aquinas, Summa Theologica, IIIa, q. 80, a. 10[11]
Receiving Often or Abstaining: Thomistic Freedom
Thomas tempers this impulse on the side of the receiver. According to his dispositions, fervor, and state of life, the faithful may be led either to commune daily or to abstain sometimes out of reverence—and both attitudes are right when born of love. Here he precisely reprises Augustine’s wisdom:
“Zacchaeus and the centurion did not contradict each other, one receiving the Lord with joy, the other saying: ‘Lord, I am not worthy’; both honored the Savior, but not in the same way.”
— Saint Thomas Aquinas, following Saint Augustine, Summa Theologica, IIIa, q. 80, a. 10[12]
The doctors’ lesson is therefore balanced: frequent communion is in itself a summit, but it must remain an act of free love, never a mechanical performance. It is precisely this balance that the following centuries will have to defend against a rigorist drift.
The Great Controversy: Rigorism versus Frequent Communion
Jansenism and Arnauld’s Book (1643)
In the 17th century, a serious crisis nearly extinguished the practice of frequent communion. The Jansenist theologian Antoine Arnauld published in 1643 a striking treatise, De la fréquente communion (On Frequent Communion), which, under the pretext of honoring the Eucharist, recommended staying away from it for long periods in order to become worthy through extended penances[13]. The pastoral effect was disastrous: out of scruples, generations of the faithful abandoned the Lord’s table, believing they honored Him by depriving themselves.
This rigorist error was the exact opposite of the Fathers: where Ambrose reproached communing “once a year”, Jansenism elevated rarity to a virtue. The Church took more than a century to heal from this, and it was against this Jansenist “contagion” — Pius X’s decree speaks of lues, the contagion raging on every side — that the great masters of spiritual life rose up.
Saint Francis de Sales: Gentleness against Rigorism
From the early 17th century, even before the Jansenist controversy, Saint Francis de Sales (1567–1622), Doctor of the Church, took the opposite stance to rigorism. In his Introduction to the Devout Life, he encouraged laypeople living in the world to commune often. His saying, addressed to Philothea, has become classic:
“Two kinds of people should often commune: the perfect, because being well disposed, they would be greatly wrong not to approach the source and fountain of perfection; and the imperfect, so that they may rightly aspire to perfection. The strong, so that they do not become weak; the weak, so that they may become strong; the sick, so that they may be healed; the healthy, so that they do not fall into sickness.” — Saint Francis de Sales, Introduction to the Devout Life, Part II, ch. 20–21[14]
The Salesian argument overturns rigorism: communion is not a reward reserved for the perfect, but a remedy offered first to the weak. The more one feels unworthy, the more one needs to approach—like a sick person to a doctor. Francis de Sales nevertheless sets a sensible condition: that the frequency be regulated by a spiritual director and accompanied by a coherent life.
Saint Alphonsus Liguori: Communion, “the Most Effective Means”
In the 18th century, Saint Alphonsus Liguori (1696–1787), Doctor of the Church and great opponent of moral rigorism, made frequent communion one of the pillars of his popular spirituality. In his devotional works—especially Visits to the Blessed Sacrament and The Practice of the Love of Jesus Christ—he presents the Eucharist as the great means to obtain perseverance and to grow in love of God. Against confessors who were too severe and sent penitents away from the holy table, he taught that even an imperfect heart, provided it is in a state of grace and desires to progress, should be encouraged to commune often[15]. His morality of the “middle way”, neither lax nor rigorist, prepared the ground for the turning point of Pius X.
Saint Pius X, “the Pope of the Eucharist”
The controversy found its magisterial conclusion at the beginning of the 20th century. Saint Pius X (1835–1914), nicknamed “the Pope of the Eucharist”, put an authoritative end to the remnants of Jansenist rigorism. His decree Sacra Tridentina Synodus (1905) recalls that frequent and daily communion is “strongly desired by Christ our Lord and by the Church” and that it must be “open to all the faithful, of whatever rank or condition”, with only two conditions: being in a state of grace and approaching with a right intention[16]. Five years later, the decree Quam singulari (1910) lowered the age of first communion to the age of reason, opening the Eucharistic table to young children[17].
The doctrinal significance of this turning point is not developed here—it is explained in How to Grow in Frequent Communion. It suffices to note that Pius X joined the Fathers across centuries of scruples: with him, the Church officially restated what Cyprian, Ambrose, and Basil already said—that the “daily” Bread is made to be received often.
The Masters of the Interior Life: Commune Often, but Well
The Holy Curé of Ars: “A Bellows-Blast on a Fire”
Saint Jean-Marie Vianney (1786–1859), the Curé of Ars and patron of priests, spoke of communion with the wonder of a poet. He made it the great means of rekindling a lukewarm soul, with an image that has become famous:
“Communion acts on the soul like a bellows-blast on a fire that is beginning to go out, but where there are still many embers; we commune and behold our soul all aflame.” — Saint Jean-Marie Vianney, Catechism on Holy Communion[18]
To those who stayed away out of a sense of unworthiness—the very argument of rigorism—the Curé of Ars opposed the logic of the remedy: “He who communes is lost in God like a drop of water in the ocean”[19]. For him, refusing communion out of false humility was like a sick person refusing the doctor. His entire pastoral ministry urged people toward the holy table: “Go to communion, my children, go to Jesus with love and trust!”[20].
The Imitation of Christ: Hunger for the Bread of Heaven
The great classic of Eucharistic devotion, The Imitation of Christ (15th century), devotes its entire fourth book to exhortation to holy communion. The author—traditionally Thomas à Kempis—gives the right tone for frequent communion: not routine, but hunger. He puts into the mouth of the faithful the ardent desire for the Bread of Heaven, and presents frequent communion as the daily help of the weak, the comfort of the traveler, the remedy for the soul that knows it cannot endure without this nourishment. This book, read and meditated on by generations of saints, has shaped Catholic sensibility: to commune often is above all to be hungry for God[21].
Saint Teresa of Avila: Close the Eyes of the Body, Open Those of the Soul
The great mystics united frequency with the quality of thanksgiving. Saint Teresa of Avila (1515–1582), Doctor of the Church, teaches that the value of communion is not measured by number, but by the attentive recollection that follows reception, when the soul truly possesses Christ present within it:
“After receiving the Lord, since you have the very Person present, strive to close the eyes of the body and open those of the soul, and look within your heart.” — Saint Teresa of Avila, The Way of Perfection, ch. 34[22]
For Teresa, frequent communion only makes sense if each communion becomes a real encounter. Frequency without heart would be vain; but frequency inhabited by love transforms the soul day by day.
The Modern Apostles of the Eucharist
The 19th and 20th centuries saw a flourishing of saints entirely devoted to the Eucharist, who prepared and extended the decree of Pius X.
Saint Peter-Julian Eymard, "the Apostle of the Eucharist"
Saint Peter-Julian Eymard (1811–1868), founder of the Congregation of the Blessed Sacrament, is called by the Church “the Apostle of the Eucharist.” His entire mission aimed to bring the faithful back to frequent communion and adoration, at a time still marked by the aftermath of Jansenism; his preaching anticipated by several decades the Eucharistic movement that would culminate in Sacra Tridentina[23]. For adoration, see What the Saints Say About Eucharistic Adoration.
Saint Thérèse of Lisieux: the hunger for daily communion
Saint Thérèse of the Child Jesus (1873–1897), Doctor of the Church, lived before the decree of Pius X, at a time when daily communion was still rare, even in Carmel. She suffered from it as a hunger. In her Story of a Soul, she expresses the burning desire for more frequent union and boldly challenges the idea that one must be perfect to approach often:
“It is not to remain in a golden ciborium that Jesus comes down from Heaven every day, but to find another Heaven infinitely dearer to Him than the first: the Heaven of our soul.”
— Saint Thérèse of the Child Jesus, Story of a Soul[24]
Her logic follows that of the Fathers and Francis de Sales: it is not our worthiness that calls for communion, but the love of Jesus who wants to descend into us. A few years after her death, Pius X would fulfill the desire she bore.
Saint Faustina: "All my strength I draw from communion"
Saint Faustina Kowalska (1905–1938), apostle of Divine Mercy, made daily communion the center of gravity of her spiritual life. At the end of her life, exhausted by illness, she confided in her Diary that without this Bread, she would collapse:
“Jesus hidden in the host is everything to me. It is from the tabernacle that I draw strength, power, courage, and light. It is there that I seek peace in moments of trial.”
— Saint Faustina Kowalska, Diary, § 1037[25]
For Faustina, frequent communion is not just one practice among others: it is the unique source from which she draws everything. Her testimony echoes, in the language of modern mysticism, Cyprian’s conviction: the Christian cannot endure without the Bread of each day.
Frequent Communion or Worthy Communion?
Saint Paul’s warning: “Let each one examine himself”
The unanimity of the saints on frequency never erases the requirement of worthiness, established from the beginning by Saint Paul:
“Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body of the Lord eats and drinks judgment on himself.”
— Saint Paul, First Letter to the Corinthians 11:28-29[26]
It was on this passage that rigorism relied to keep the faithful away. But the saints read it quite differently: Paul does not say “communicate rarely,” he says “examine yourselves.” The answer is therefore not abstinence, but purification—through regular confession, repentance, and preparation of the heart.
The saints’ response: often AND worthily
Here is where the apparent tension between the two registers is resolved. The saints do not choose between frequency and worthiness: they hold both together. Receiving often presupposes keeping oneself pure; and keeping oneself pure only makes sense to receive often. Regular confession thus becomes the sister of frequent communion—a subject treated separately in What the Saints Say About Regular Confession. Careful preparation and thanksgiving, spoken of by Teresa of Avila and the decree of Pius X, are not obstacles to frequency: they are the wings that make it fruitful. Concrete means for this can be found in How to Grow in Frequent Communion.

Frequent Communion and the Divine Will
For the spirituality of the Divine Will transmitted by the Servant of God Luisa Piccarreta, frequent communion receives a particular light. Receiving Christ often is not merely obtaining a punctual grace: it is opening oneself to a continuous life in God, where the soul seeks to remain united to the Lord not by moments, but always, like a communion that never ceases. The sacramental communion then becomes the nourishment of a permanent communion of the human will with the Divine Will. This extension, proper to Luisa’s spirituality, touches the heart of The Divine Will: the Eucharistic table appears as the school and source of a union without shadow, in the image of Mary, who lived every moment in perfect communion with God.
What do the saints say about frequent communion?
If we gather what the saints have repeated over twenty centuries, some convictions return with striking consistency — from the Fathers of Carthage to Saint Faustina. They are not developed here: their practical applications are the subject of How to Grow in Frequent Communion. But their convergence deserves to be noted as a common wisdom:
- Receive often, because Christ called this Bread “daily” (Ambrose, Cyprian, Pius X).
- Communion to live, for “whoever eats my flesh has eternal life” (Jn 6; Basil).
- Approach with a pure heart, never out of routine or scruple (Chrysostom, Paul).
- See communion as a remedy, offered first to the weak, not a reward for the perfect (Francis de Sales, Curé d'Ars).
- Care for preparation and thanksgiving, so that each communion is a true encounter (Therese of Avila).
- Make it the source of everything, strength for fighters and the sick (Cyprian, Faustina).
- And never oppose frequency and dignity: the saints hold both together.
These convictions are not a mechanical recipe, but the distilled experience of twenty centuries of holiness. They all say the same thing: frequent communion is not an optional devotion for fervent souls, but the daily bread that Christ wanted to give to all who hunger for him.

Saint Thomas Aquinas takes it up while ascribing it to Augustine (Summa Theologica, IIIa, q. 80, a. 10), but no verifiable locus can be found in Augustine: the saying is absent from Sermon 57 on the Lord’s Prayer as from the rest of the sermon corpus.

12Antoine Arnauld (1612-1694), De la fréquente communion (On Frequent Communion, Paris, 1643): a major work of the Jansenist movement which, by demanding long penitential preparations before Communion, had the effect of keeping the faithful away from the Eucharistic table for a long time. The rigorist orientation of the work was opposed by defenders of frequent Communion and ultimately disavowed by the Church (cf. decree Sacra Tridentina, 1905).
13Saint Francis de Sales (1567-1622), Introduction to the Devout Life (1609), Part II, ch. 21 (“How one must communicate”): “Tell them that two kinds of people should often communicate: the perfect […] and the imperfect, so that they may rightly aspire to perfection; the strong, so that they do not become weak, and the weak, so that they may become strong; the sick, so that they may be healed, and the healthy, so that they do not fall into sickness.” A saying proper to Sales, addressed to Philothea: he does not attribute it to Saint Catherine of Siena (whom he quotes in the preceding chapter, ch. 20 “On Frequent Communion”, for her reply on daily communion). Text of the 1619 edition (verified on the Boulenger 1909 edition, fr.wikisource).
14Saint Alphonsus Liguori (1696-1787), Doctor of the Church, notably Visits to the Blessed Sacrament and to the Most Holy Virgin (Visite al SS. Sacramento, 1745 — 31 visits, one for each day of the month) and The Practice of Love of Jesus Christ (Pratica di amar Gesù Cristo, Naples, 1768), ch. II, the Eucharistic chapter (“Quanto merita d’esser amato per il SS. Sacramento dell’Altare”, which exhorts to frequent communion): the Eucharist is presented as the great means to grow in love of God and obtain perseverance. Founder of the Redemptorists and opponent of moral rigorism, Alphonsus encourages frequent Communion for well-disposed faithful.
15Saint Pius X (1835-1914), decree Sacra Tridentina Synodus of the Sacred Congregation of the Council (December 20, 1905): frequent and daily Communion, “strongly desired by Christ our Lord and by the Church, must be open to all the faithful, of whatever rank and condition they may be,” provided they are in a state of grace and approach “with a right and pious intention” (recta piaque mente)—not out of routine, vanity, or human respect, but to please God, unite more closely to Him by charity, and remedy their weaknesses. In its historical preamble, the decree names the cause of the evil: “Defervescente interim pietate, ac potissimum postea Ianseniana lue undequaque grassante…” (“piety having grown lukewarm, and above all the Jansenist contagion raging on every side…”) — the Latin word is lues (contagion, scourge), not “poison”. Text: Acta Sanctae Sedis 38 (1905-1906), pp. 400-406; decree of December 20, 1905, approved by Pius X on December 17, 1905. Cf. How to Grow in Frequent Communion for the detailed text.
16Saint Pius X, decree Quam singulari of the Sacred Congregation of the Sacraments (August 8, 1910): sets the age of First Communion at “the age of reason,” about seven years old, against the custom of postponing it to adolescence. Complement to Sacra Tridentina (1905) in the Eucharistic policy of Pius X, “the pope of the Eucharist.”
17Saint John Vianney (1786-1859), Curé of Ars, catechism on Holy Communion, collected in The Spirit of the Curé of Ars (Abbé Alfred Monnin): “Communion acts on the soul like a bellows-blast on a fire that is beginning to go out, but where there are still many embers.”
18Saint John Vianney, catechism on Holy Communion, in The Spirit of the Curé of Ars: “He who communes is lost in God like a drop of water in the ocean: they can no longer be separated.”
19Saint John Vianney, exhortation reported by his biographers (Abbé Monnin, The Curé of Ars): “Go to Communion, my children, go to Jesus with love and trust; go to live from Him, so as to live for Him.”
20The Imitation of Christ (15th century, attributed to Thomas à Kempis), book IV (“On the Sacrament of the Altar” / “Exhortation to Holy Communion”), notably ch. 3 (on the usefulness of communicating often) and ch. 10 (not to neglect holy communion lightly): the entire fourth book is devoted to Eucharistic devotion and exhortation to receive often and worthily the Body of Christ, presented as the necessary bread for the traveler and the remedy for the weak.
21Saint Teresa of Ávila (1515-1582), The Way of Perfection, ch. 34: “After receiving the Lord, since you have the very Person present, strive to close the eyes of the body and open those of the soul, and look within your heart.” Advice on thanksgiving after Communion. Reference edition: Complete Works, Carmel translation (Cerf / Le Seuil).
22Saint Peter Julian Eymard (1811-1868), founder of the Congregation of the Blessed Sacrament (1856) and the Servants of the Blessed Sacrament, canonized in 1962, called “the apostle of the Eucharist.” Biographical note: as no writing of Eymard’s located at page level could be opened in session, no doctrinal saying is here attributed to him; his mission for frequent Communion and adoration, which prepared the Eucharistic movement leading to the decrees of Saint Pius X, is summarized as a historical fact.
23Saint Thérèse of the Child Jesus (1873-1897), Story of a Soul, manuscript A: “It is not to remain in a golden ciborium that [Jesus] comes down every day from Heaven, but to find another Heaven infinitely dearer to Him than the first: the Heaven of our soul.” Thérèse, who died before Pius X’s decree (1905), ardently desired more frequent Communion. Reference edition: Complete Works, Cerf / DDB.
24Saint Faustina Kowalska (1905-1938), Diary, § 1037: “Jesus hidden in the host is everything to me. It is from the tabernacle that I draw strength, power, courage, and light; it is there that I seek peace in moments of trial.” Reference edition: Diary — Divine Mercy in My Soul, Editions of the Marie-Queen of Peace Association / Krakow.
25First Letter of Saint Paul to the Corinthians 11:28-29, after the official liturgical translation: “Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body of the Lord, eats and drinks judgment on himself.”
