9 We indeed hold such an opinion concerning the training of this holy virgin, and the Christian humility in which she was nourished and brought up, as to be assured that when she read these words, if she did read, them, she would break out into lamentations, and humbly smite her breast, and perhaps burst into tears, and pray in faith to the Lord to whose service she was dedicated and by whom she was sanctified, pleading with Him that these were not her own words, but another's, and asking that her faith might not be such as to believe that she had anything whereof to glory in herself and not in the Lord. For her glory is in herself, not in the words of another, as the apostle says: “Let every man prove his own work, and then shall he have glory (rejoicing) in himself alone, and not in another.” But God forbid that her glory should be in herself, and not in Him to whom the Psalmist says, “You are my glory, and the lifter up of mine head.” For her glory is then profitably in herself, when God, who is in her, is Himself her glory, from whom she has every good, by which she is good, and shall have all things by which she shall be made better, in as far as she may become better in this life, and by which she shall be made perfect when rendered so by divine grace, not by human praise. “For her soul shall be praised in the Lord,” “who satisfies her desire with good things,” because He Himself has inspired this desire, that His virgin should not boast of any good, as if she had not received it.
10. Inform us, then, in reply to this letter, whether we have judged truly in supposing these to be your daughter's sentiments. For we know well that you and all your family are, and have been, worshippers of the indivisible Trinity. But human error insinuates itself in other forms than in erroneous opinions concerning the indivisible Trinity. There are other subjects also, in regard to which men fall into very dangerous errors. As, for example, that of which we have spoken in this letter at greater length, perhaps, than might have sufficed to a person of your steadfast and pure wisdom. And yet we know not to whom, except to God, and therefore to the Trinity, wrong is done by the man who denies that the good that comes from God is from God; which evil may God avert from you, as we believe He does! May God altogether forbid that the book out of which we have thought it our duty to extract some words, that they might be more easily understood, should produce any such impression, we do not say on your mind, or on that of the holy virgin your daughter, but on the mind of the least deserving of your male or female servants.
11. But if you study more carefully even those words in which the writer appears to speak in favour of grace or the aid of God, you will find them so ambiguous that they may have reference either to nature or to knowledge, or to forgiveness of sins. For even in regard to that which they are forced to acknowledge, that we ought to pray that we may not enter into temptation, they may consider that the words mean that we are so far helped to it that, by our praying and knocking, the knowledge of the truth is so revealed to us that we may learn what it is our duty to do, not so far as that our will receives strength, whereby we may do that which we learn to be our duty; and as to their saying that it is by the grace or help of God that the Lord Christ has been set before us as an example of holy living, they interpret this so as to teach the same doctrine, affirming, namely, that we learn by His example how we ought to live, but denying that we are so aided as to do through love what we know by learning.
12. Find in this book, if you can, anything in which, excepting nature and the freedom of the will (which pertains to the same nature), and the remission of sin and the revealing of doctrine, any such aid of God is acknowledged as that which he acknowledges who said: “When I perceived that no man can be continent unless God bestow the gift, and that this also is a point of wisdom to know whose gift it is, I went to the Lord, and made my supplication to Him.” For he did not desire to receive, in answer to his prayer, the nature in which he was made; nor was he solicitous to obtain the natural freedom of the will with which he was made; nor did he crave the remission of sins, seeing that he prayed rather for continence, that he might not sin; nor did he desire to know what he ought to do, seeing that he already confessed that he knew whose gift this continence was; but he wished to receive from the Spirit of wisdom such strength of will, such ardour of love, as should suffice for fully practising the great virtue of continence. If, therefore, you succeed in finding any such statement in that book, we will heartily thank you if, in your answer, you deign to inform us of it.
13. It is impossible for us to tell how greatly we desire to find in the writings of these men, whose works are read by very many for their pungency and eloquence, the open confession of that grace which the apostle vehemently commends, who says that “God has given to every man the measure of faith,” “without which it is impossible to please God,” “by which the just live,” “which works by love,” before which and without which no works of any man are in any respect to be reckoned good, since “whatsoever is not of faith is sin.” He affirms that God distributes to every man, and that we receive divine assistance to live piously and justly, not only by the revelation of that knowledge which without charity “puffs up,” but by our being inspired with that “love which is the fulfilling of the law,” and which so edifies our heart that knowledge does not puff it up. But hitherto I have failed to find any such statements in the writings of these men.
14. But especially we should wish that these sentiments should be found in that book from which we have quoted the words in which the author, praising a virgin of Christ as if no one except herself could confer on her spiritual riches, and as if these could not exist except from herself, does not wish her to glory in the Lord, but to glory as if she had not received them. In this book, though it contain neither his name nor your own honoured name, he nevertheless mentions that a request had been made to him by the mother of the virgin to write to her. In a certain epistle of his, however, to which he openly attaches his name, and does not conceal the name of the sacred virgin, the same Pelagius says that he had written to her, and endeavours to prove, by appealing to the said work, that he most openly confessed the grace of God, which he is alleged to have passed over in silence, or denied. But we beg you to condescend to inform us, in your reply, whether that be the very book in which he has inserted these words about spiritual riches, and whether it has reached your Holiness.
