Bernard states that the Festival of the Conception was new; that it rested on no legitimate foundation; and that it should not have been instituted without consulting the Apostolic See, to whose opinion he submits.
1. It is well known that among all the Churches of France that of Lyons is first in importance, whether we regard the dignity of its See, its praiseworthy regulations, or its honourable zeal for learning. Where was there ever the vigour of discipline more flourishing, a more grave and religious life, more consummate wisdom, a greater weight of authority, a more imposing antiquity? Especially in the Offices of the Church, that of Lyons has always shown itself opposed to attempts at sudden innovation, and it is a proof of her fulness of judgment that she has never suffered herself to be stained with the mark of rash and hasty levity. Wherefore I cannot but wonder that there should have been among you at this time some who wished to sully this splendid fame of your Church by introducing a new Festival, a rite which the Church knows nothing of, and which reason does not prove, nor ancient tradition hand down to us. Have we the pretension to be more learned or more devoted than the Fathers? It is a dangerous presumption to establish in such a matter what their prudence left unestablished. And the matter in question is of such a nature that it could not possibly have escaped the diligence of the Fathers if they had not thought that they ought not to occupy themselves with it.
2. The Mother of the Lord, you say, ought greatly to be honoured. You say well, but the honour of a queen loves justice. The royal Virgin does not need false honour, since she is amply supplied with true titles to honour and badges of her dignity. Honour indeed the purity of her flesh, the sanctity of her life, wonder at her motherhood as a virgin, adore her Divine offspring. Extol the prodigy by which she brought into the world without pain the Son, whom she had conceived without concupiscence. Proclaim her to be reverenced by the angels, to have been desired by the nations, to have been known beforehand by Patriarchs and Prophets, chosen by God out of all women and raised above them all. Magnify her as the medium by whom grace was displayed, the instrument of salvation, the restorer of the ages; and finally extol her as having been exalted above the choirs of angels to the celestial realms. These things the Church sings concerning her, and has taught me to repeat the same things in her praise, and what I have learnt from the Church I both hold securely myself and teach to others; what I have not received from the Church I confess I should with great difficulty admit. I have received then from the Church that day to be reverenced with the highest veneration, when being taken up from this sinful earth, she made entry into the heavens; a festival of most honoured joy. With no less clearness have I learned in the Church to celebrate the birth of the Virgin, and from the Church undoubtedly to hold it to have been holy and joyful; holding most firmly with the Church, that she received in the womb that she should come into the world holy. And indeed I read concerning Jeremiah, that before he came forth from the womb [ ventre : otherwise de vulva] he was sanctified, and I think no otherwise of John the Baptist, who, himself in the womb of his mother, felt the presence of his Lord in the womb (S. Luke i.41). It is matter for consideration whether the same opinion may not be held of holy David, on account of what he said in addressing God: In Thee I have been strengthened from the womb: Thou art He who took me out of my mother's bowels (Ps. lxxi.6); and again: I was cast upon Thee from the womb: Thou art my God from my mother's belly (Ps. xxii.10). And Jeremiah is thus addressed: Before I formed thee in the belly I knew thee; and before thou camest out of the womb I sanctified thee (Jer. i.5). How beautifully the Divine oracle has distinguished between conception in the womb and birth from the womb! and showed that if the one was foreseen only, the other was blessed beforehand with the gift of holiness: that no one might think that the glory of Jeremiah consisted only in being the object of the foreknowledge of God, but also of His predestination.
3. Let us, however, grant this in the case of Jeremiah. What shall be said of John the Baptist, of whom an angel announced beforehand that he should be filled with the Holy Ghost, even from his mother's womb? I cannot suppose that this is to be referred to predestination or to foreknowledge. For the words of the angel were without doubt fulfilled in their time, as he foretold; and the man (as cannot be doubted) filled with the Holy Ghost at the time and place appointed, as he predicted. But most certainly the Holy Ghost sanctified the man whom He filled. But how far this sanctification availed against original sin, whether for him, or for that prophet, or for any other who was thus prevented by grace, I would not rashly determine. But of these holy persons whom God has sanctified, and brought forth from the womb with the same sanctification which they have received in the womb, I do not hesitate to say that the taint of original sin which they contracted in conception, could not in any manner take away or fetter by the mere act of birth, the benediction already bestowed. Would any one dare to say that a child filled with the Holy Ghost, would remain notwithstanding a child of wrath; and if he had died in his mother's womb, where he had received this fulness of the Spirit, would endure the pains of damnation? That opinion is very severe; I, however, do not dare to decide anything respecting the question by my own judgment. However that may be, the Church, which regards and declares, not the nativity, but only the death of other saints as precious, makes a singular exception for him of whom an angel singularly said, and many shall rejoice in his birth (Luke i.14., 15), and with rejoicing honours his nativity. For why should not the birth be holy, and even glad and joyful, of one who leaped with joy even in the womb of his mother?
4. The gift, therefore, which has certainly been conferred upon some, though few, mortals, cannot for a moment be supposed to have been denied to that so highly favoured Virgin, through whom the whole human race came forth into life. Beyond doubt the mother of the Lord also was holy before birth; nor is holy Church at all in error in accounting the day of her nativity holy, and celebrating it each year with solemn and thankful joy. I consider that the blessing of a fuller sanctification descended upon her, so as not only to sanctify her birth, but also to keep her life pure from all sin; which gift is believed to have been bestowed upon none other born of women. This singular privilege of sanctity, to lead her life without any sin, entirely befitted the queen of virgins, who should bear the Destroyer of sin and death, who should obtain the gift of life and righteousness for all. Therefore, her birth was holy, since the abundant sanctity bestowed upon it made it holy even from the womb.
5. What addition can possibly be made to these honours? That her conception, also, they say, which preceded her honourable birth, should be honoured, since if the one had not first taken place, neither would the other, which is honoured. But what if some one else, following a similar train of reasoning, should assert that the honours of a festival ought to be given to each of her parents, then to her grand-parents, and then to their parents, and so on ad infinitum? Thus we should have festivals without number. Such a frequency of joys befits Heaven, not this state of exile. It is the happy lot of those who dwell there, not of strangers and pilgrims. But a writing is brought forward, given, as they say, by revelation from on high,  as if any one would not be able to bring forward another writing in which the Virgin should seem to demand the same honours to her parents also, saying, according to the commandment of the Lord, Honour thy father and thy mother (Exod. xx.12). I easily persuade myself not to be influenced by such writings, which are supported neither by reason nor by any certain authority. For how does the consequence follow that since the conception has preceded the birth, and the birth is holy, the conception should be considered holy also? Did it make the birth holy because it preceded it? Although the one came first that the other might be, yet not that it might be holy. From whence came that holiness to the conception which was to be transmitted to the birth which followed? Was it not rather because the conception preceded without holiness that it was needful for the being conceived to be sanctified, that a holy birth might then follow? Or shall we say that the birth which was later than the conception shared with it its holiness? It might be, indeed, that the sanctification which was worked in her when conceived passed over to the birth which followed; but it could not be possible that it should have a retrospective effect upon the conception which had preceded it.
6. Whence, then, was the holiness of that conception? Shall it be said that Mary was so prevented by grace that, being holy before being conceived, she was therefore conceived without sin; or that, being holy before being born, she has therefore communicated holiness to her birth? But in order to be holy it is necessary to exist, and a person does not exist before being conceived. Or perhaps, when her parents were united, holiness was mingled with the conception itself, so that she was at once conceived and sanctified. But this is not tenable in reason. For how can there be sanctity without the sanctifying Spirit, or the co-operation of the Holy Spirit with sin? Or how could there not be sin where concupiscence was not wanting? Unless, perhaps, some one will say that she was conceived by the Holy Spirit, and not by man, which would be a thing hitherto unheard of. I say, then, that the Holy Spirit came upon her, not within her, as the Angel declared: The Holy Spirit shall come upon thee (S. Luke i.35). And if it is permitted to say what the Church thinks, and the Church thinks that which is true, I say that she conceived by the Holy Spirit, but not that she was conceived by Him; that she was at once Mother and Virgin, but not that she was born of a virgin. Otherwise, where will be the prerogative of the Mother of the Lord, to have united in her person the glory of maternity and that of virginity, if you give the same glory to her mother also? This is not to honour the Virgin, but to detract from her honour. If, therefore, before her conception she could not possibly be sanctified, since she did not exist, nor in the conception itself, because of the sin which inhered in it, it remains to be believed that she received sanctification when existing in the womb after conception, which, by excluding sin, made her birth holy, but not her conception.
7. Wherefore, although it has been given to some, though few, of the sons of men to be born with the gift of sanctity, yet to none has it been given to be conceived with it. So that to One alone should be reserved this privilege, to Him who should make all holy, and coming into the world, He alone, without sin should make an atonement for sinners. The Lord Jesus, then, alone was conceived by the Holy Ghost, because He alone was holy before He was conceived. He being excepted, all the children of Adam are in the same case as he who confessed of himself with great humility and truth, I was shapen in iniquity, and in sin hath my mother conceived me (Ps. li.6).
8. And as this is so, what ground can there be for a Festival of the Conception of the Virgin? On what principle, I say, is either a conception asserted to be holy which is not by the Holy Ghost, not to say that it is by sin, or a festival be established which is in no wise holy? Willingly the glorious Virgin will be without this honour, by which either a sin seems to be honoured or a sanctity supposed which is not a fact. And, besides, she will by no means be pleased by a presumptuous novelty against the custom of the Church, a novelty which is the mother of rashness, the sister of superstition, the daughter of levity. For if such a festival seemed advisable, the authority of the Apostolic See ought first to have been consulted, and the simplicity of inexperienced persons ought not to have been followed so thoughtlessly and precipitately. And, indeed, I had before noted that error in some persons; but I appeared not to take notice of it, dealing gently with a devotion which sprang from simplicity of heart and love of the Virgin. But now that the superstition has taken hold upon wise men, and upon a famous and noble Church, of which I am specially the son,  I know not whether I could longer pass it over without gravely offending you all. But what I have said is in submission to the judgment of whosoever is wiser than myself; and especially I refer the whole of it, as of all matters of a similar kind, to the authority and decision of the See of Rome, and I am prepared to modify my opinion if in anything I think otherwise than that See.
 A writing of this kind is attributed to an English abbot named Elsin in the works of Anselm, pp. 505, 507 of the new edition.  The Church of Lyons was the Mother Church of Bernard because of its "metropolitan rights," as he himself says in Letter 172, since he was born at Fontaines, near Dijon, and lived at the monastery of Clairvaux, both of which places were in the Diocese of Langres and Province of Lyons.
