S. Bernardi Abbatis et Ecclesiæ Doctoris ~ III. classis
Feria Quinta infra Hebdomadam XII post Octavam Pentecostes — XX Augusti
Epistola: Ecclesiasticus 39:6–14 · Evangelium: Matthæus 5:13–19
I. Liturgical Context
On the twentieth of August the Church keeps the memory of Bernard of Clairvaux, abbot of a hidden valley in Burgundy who became, against every inclination of his own heart, the most public man of the twelfth century. He entered Cîteaux in 1113 with some thirty companions whom he had himself persuaded to abandon the world; within a few years he was sent to found Clairvaux; from that cloister he counselled popes, rebuked kings, arbitrated a papal schism, preached a crusade, confuted Abelard, and composed a body of writing so suffused with Scripture that later ages called him Doctor Mellifluus, the doctor flowing with honey. He died on 20 August 1153 and was canonized in 1174. Pius VIII declared him a Doctor of the Church in 1830.
The Mass is that of the Common of Doctors, In medio Ecclesiæ. Its Introit places the saint in the midst of the assembly, where God opens his mouth and fills him with the spirit of wisdom and understanding. The Epistle and Gospel assigned to Doctors are not arbitrary ornaments. They describe a single movement: wisdom is received from above, stored in the heart, and then poured out for the Church — and the one who pours it out must himself remain uncorrupted, or his teaching spoils. Bernard is the living commentary on both readings. He drew everything from prayer and the lectio of the sacred page, and what he drew he gave away without reserve, yet he never ceased to fear that the giving might hollow out the giver. That fear, rightly understood, is the theme of this feast.
The heading above follows the Thursday of the twelfth week after Pentecost. In the 1962 calendar the ferial Mass yields entirely to the feast of the third class, but the season still frames it: we are in the long green stretch of the Church’s pilgrimage, where the Sunday Gospels teach the works of charity and the saints show those works accomplished.
II. The Epistle: Ecclesiasticus 39:6–14
The passage belongs to the son of Sirach’s portrait of the ideal scribe, the man who gives his soul to the study of the law of the Most High. The verses chosen for the Doctors begin at the turning point of that portrait. The scribe has sought out the wisdom of the ancients, has travelled among foreign nations, has risen early to seek the Lord. Now the text shifts from what the scribe does to what God does in him: if the great Lord wills, He will fill him with the spirit of understanding, and he will pour forth the words of his wisdom as showers, and in prayer he will confess to the Lord.
Three things stand out.
First, the priority of grace. The scribe labours, but the filling is God’s. Si enim Dominus magnus voluerit — “if the great Lord will.” The Latin of the Vulgate makes the conditional unmistakable. Learning does not manufacture wisdom; it prepares a vessel that God may or may not choose to fill. Bernard, who had been schooled at Châtillon and who knew the Latin classics well, spoke of his true teachers as the oaks and beeches of the forest, meaning that he had learned more on his knees than at his desk. He did not despise study; he subordinated it.
Second, the image of outpouring. The wise man “will pour forth the words of his wisdom as showers.” The verb is one of liquid abundance, and the Church’s title for Bernard — mellifluus — is drawn from the same semantic field. What has been received must flow out. Sirach will say shortly afterward, in verses not read at Mass but governing the whole passage, that the scribe’s memory will not depart and his name will live from generation to generation, and that the nations will declare his wisdom. The private act of receiving wisdom has a public and even a posthumous fruit.
Third, the unity of wisdom and prayer. “In prayer he will confess to the Lord, and He will direct his counsel.” The scribe’s learning is not a closed circuit of erudition. It returns to God in confession and praise, and only from that return does right counsel come. This is the Thomistic reditus already present in the Old Covenant: what goes out from God comes back to God, and the wise man is the one through whom the circuit runs.
Rabanus Maurus, commenting on this book in the ninth century, reads the scribe figurally as the doctor of the Church, who opens the treasures of both Testaments and gives to each hearer the portion suited to him. His exposition is derivative, as most Carolingian commentary is, but it shows how early the Church heard this passage as a description of her teachers rather than merely of Israel’s sages.
III. The Gospel: Matthew 5:13–19
Our Lord has just completed the Beatitudes and has told the disciples that they are blessed when men revile and persecute them. Immediately He tells them what they are: Vos estis sal terræ. Vos estis lux mundi. You are the salt of the earth. You are the light of the world. The two images are not synonyms. Salt works from within, invisibly, preserving from corruption; light works from without, visibly, showing the way. The disciple is both. He must have an interior savour that keeps him and those around him from rot, and an exterior clarity that cannot be hidden.
The Fathers linger on the warning: Quod si sal evanuerit, in quo salietur? If the salt lose its savour, wherewith shall it be salted? It is good for nothing but to be cast out and trodden under foot.
Saint John Chrysostom, in his homilies on this Gospel, draws the obvious and terrible inference: other things, when they spoil, may be seasoned and restored by salt, but if the salt itself spoils there is nothing left to season it. The teacher who falls cannot be healed by the very means he was meant to supply to others. Chrysostom adds that salt does not make fresh what has already rotted; its work is to preserve what is still sound. The apostles are therefore not sent to restore the whole world from corruption by their own power but to keep from further decay what Christ has already renewed by grace.
Saint Augustine, in his treatise on the Sermon on the Mount, explains the loss of savour as cowardice: the disciple who, from fear of temporal persecution, abandons the things of heaven has become insipid, and he is trodden by men not because he is persecuted but because he has consented to be persecuted into silence. The one who suffers persecution for truth is not trodden underfoot; the one who flees it is. Augustine also notes the sequence — salt before light — and reads it as interior before exterior. One must first be preserved from corruption in oneself before one can illuminate another.
Saint Hilary of Poitiers, in his commentary on Matthew, takes salt as the sign of the apostolic word that preserves bodies for incorruption, since salt keeps flesh from decay and the preaching of the apostles keeps the faithful for the resurrection. Salt that has lost its power, he says, is the teacher who has lost the fire of faith by which the word is seasoned.
Saint Jerome, more briefly, treats the city on a mountain as the Church that cannot be hidden, and the lamp under the bushel as the teacher who, possessing doctrine, keeps it to himself from fear or sloth. Jerome is scornful of the learned who will not teach.
Then the Gospel turns, as the Epistle did, from the teacher’s office to the teacher’s own fidelity. “Do not think that I am come to destroy the law or the prophets. I am not come to destroy, but to fulfil.” And the closing verse, which the Church reads over every Doctor: Qui autem fecerit et docuerit, hic magnus vocabitur in regno cælorum. He who shall do and teach, he shall be called great in the kingdom of heaven. The order is deliberate — fecerit before docuerit. Chrysostom insists on it: Christ places doing first because teaching without doing is the very savourlessness just condemned. Augustine concurs: the one who teaches what he does not do is not great but least, whatever his learning.
IV. Synthesis: The Circuit of Wisdom
Set the two readings side by side and one pattern emerges. In Ecclesiasticus, wisdom comes down from God into the scribe and goes out from the scribe as rain, while the scribe himself returns to God in prayer. In Matthew, the disciple is constituted salt and light by Christ’s word, is sent to season and to shine, and is warned that he must himself remain savoury — must do as well as teach — or the whole movement collapses.
Saint Thomas gives this circuit its classical form. In the Secunda Secundæ, treating of the religious state, he argues that the highest form of life is not pure contemplation nor pure action but the life that hands on to others what it has contemplated — contemplata aliis tradere — as a lamp gives more than it merely possesses light. The contemplative who teaches from the abundance of contemplation is compared to a vessel that overflows rather than one that is emptied. This is the theological structure of the Doctor’s office, and it is the structure of Bernard’s life. He is the monk who never wished to leave the cloister and was forever being drawn out of it, and he resolved the tension not by choosing one over the other but by making the second flow from the first.
Bernard himself gave the principle its most memorable image in his sermons on the Canticle. He distinguishes the canal from the reservoir. The canal, he says, pours out water as soon as it receives it; the reservoir waits until it is full and then gives from its overflow without loss to itself. There are too many canals in the Church, he laments, and too few reservoirs. The man who teaches before he is filled empties himself and nourishes no one. The man who is filled first teaches from abundance and is not diminished. Here is the Epistle’s “if the great Lord will, He will fill him” and the Gospel’s “salt that keeps its savour,” united in a single pastoral counsel.
The exitus–reditus spine of the whole Mass is now visible. Wisdom goes out from God (exitus) into the scribe, the apostle, the Doctor. It goes out again from them into the Church. And it returns (reditus) in prayer, in confession, in the praise of the nations, and in the final judgment where the one who did and taught is called great in the kingdom. The Doctor is not a terminus but a conduit — yet a conduit of a particular kind, a reservoir and not a canal, who must be full before he flows and who remains full because he flows. The savourless salt is the conduit that has stopped receiving while still pretending to give.
This also explains why the Church reads the verses on the Law’s permanence over her Doctors. The Doctor does not innovate. He fulfils. He receives the deposit whole and hands it on whole, not one jot or tittle lost, and his greatness lies in the fidelity of the transmission, not in the originality of the content. Bernard’s sharpest controversies — with Abelard above all — were fought on exactly this ground. He feared that a theology driven by dialectical ingenuity would lose its savour, would become clever and insipid at once. Whatever one judges of the particulars, the instinct was the Gospel’s own.
V. Devotional Application
The readings are addressed to Doctors, but the Church reads them aloud to all the faithful, and their application is not limited to the learned.
Every baptized Christian is salt and light in his own measure. The parent who teaches the Faith to a child, the friend who answers an honest question, the layman who corrects an error gently at table — each is pouring out what he has received, and each is subject to the same law: he must be filled before he flows, and he must do before he teaches.
Bernard’s counsel about canals and reservoirs is therefore a rule of life. Before speaking of God, one must have listened to God. The shortest and surest form of this listening is the daily, unhurried reading of Scripture — not study, at first, but lectio, the reading that waits to be filled. Bernard himself knew the Psalter so intimately that his prose is often a mosaic of its phrases without his seeming to notice. That only comes from years of letting the sacred text soak in.
The second application is the fear of savourlessness. It is possible to speak of holy things with fluency and to be inwardly empty. Augustine’s diagnosis is worth examining one’s conscience by: have I fallen silent about the Faith out of fear of ridicule, loss of standing, or discomfort? Have I let the lamp be covered because the bushel was more comfortable? This is not a summons to contentiousness — Bernard was fierce, but he was fierce in charity and he wept over his own severity — but to the plain, uncovered witness of a life in which the Faith is visibly operative.
The third application is the ordering of action to contemplation. Many of the faithful today are canals by necessity: they have responsibilities that pour them out continuously. Bernard would not tell such people to abandon their duties. He would tell them to find, even in a crowded day, the moments of filling — a morning offering made with attention, a decade of the Rosary said slowly, the reading of a single verse held in the mind — so that what flows out has a source.
VI. Collect
Deus, qui populo tuo æternæ salutis beatum Bernardum ministrum tribuisti: præsta, quæsumus; ut, quem Doctorem vitæ habuimus in terris, intercessorem habere mereamur in cælis. Per Dominum.
O God, who didst give blessed Bernard to Thy people as a minister of eternal salvation: grant, we beseech Thee, that we who have had him as a teacher of life on earth may deserve to have him as an intercessor in heaven. Through our Lord.
The prayer names Bernard twice over: minister and Doctor. The first word recalls that he held no office higher than abbot, that his authority in the Church was entirely that of a servant. The second recalls that his service was teaching — Doctor vitæ, a teacher not of a subject but of life. The petition then performs the very circuit the readings describe: what was given on earth is sought again in heaven; the one who poured out wisdom below is asked to pour out intercession above. The Doctor’s outflowing does not end with his death. It returns to God and comes back to the Church as prayer.
VII. Aspiration
Fill me first, O Lord, and then let me flow; make me a reservoir and not a canal; keep Thy salt in me savoury, that I may do before I teach, and teach only what I have received from Thee.
VIII. For Further Study
Those who wish to go deeper in the Lives of the Saints path may take up Bernard’s own Sermones super Cantica Canticorum, especially the eighteenth sermon on the canal and the reservoir, and the De consideratione, written for his former monk Pope Eugenius III, which is the most searching treatment ever composed of how a man of action may remain a man of prayer. William of Saint-Thierry’s Vita prima is the earliest life, written by a friend who knew him.
In the Theology and Doctrine path, the relevant questions are Saint Thomas’s treatment of the contemplative and active lives and of the religious state in the Secunda Secundæ, where the principle contemplata aliis tradere is set out.
In the Sacred Liturgy path, the Common of Doctors In medio Ecclesiæ rewards study as a whole: its Introit, Gradual, Alleluia, and Communion form a single meditation on the mouth that God opens and fills.
The patristic texts cited above are the homilies of Saint John Chrysostom on Matthew, Saint Augustine’s De sermone Domini in monte, Saint Hilary’s commentary on Matthew, and Saint Jerome’s commentary on Matthew. Rabanus Maurus’s commentary on Ecclesiasticus supplies the Carolingian figural reading of the scribe.
IX. Source Transparency
The biographical outline of Saint Bernard — entry into Cîteaux in 1113, foundation of Clairvaux, death on 20 August 1153, canonization in 1174, and the title of Doctor conferred in 1830 — rests on documentary witness of the first rank: the Vita prima, contemporary charters and letters, the bull of canonization, and the papal act of 1830. The attribution of the canal-and-reservoir image to Bernard’s eighteenth sermon on the Canticle is secure in the critical edition of his works. The saying about oaks and beeches as his teachers is reported by William of Saint-Thierry and belongs to strongly attested tradition rather than to Bernard’s own pen.
Patristic material is given as paraphrase with locus, not as verbatim quotation. Chrysostom’s homilies on Matthew are found in the Patrologia Græca; Augustine’s treatise on the Sermon on the Mount in the Corpus Christianorum Series Latina; Hilary’s commentary on Matthew in Sources Chrétiennes; Jerome’s commentary on Matthew in the Corpus Christianorum Series Latina; Rabanus Maurus in the Patrologia Latina. Saint Thomas is cited to the level of the question.
The Collect is given in the form commonly transmitted for this feast and is presented here pending collation against a printed 1962 Missale Romanum. The reader is asked to treat the Latin text accordingly until that collation is complete.
