I Wrote again to the same persons another treatise, which I entitled On Rebuke and Grace, because I had been told that some one there had said that no man ought to be rebuked for not doing God’s commandments, but that prayer only should be made on his behalf, that he may do them. This book begins on this wise, “I have read your letters, dearly beloved brother Valentine.”

In the first part of the book he proves that the perseverance by which a man perseveres in Christ to the end is God's gift; for that it is a mockery to ask of God that which is not believed to be given by God. Moreover, that in the Lord's prayer scarcely anything is asked for but perseverance, according to the exposition of the martyr Cyprian, by which exposition the enemies to this grace were convicted before they were born.

This treatise was written about 400 A.D. Concerning it Aug. in Retract. Book II. c. xviii., says: I have written seven books on Baptism against the Donatists, who strive to defend themselves by the authority of the most blessed bishop and martyr Cyprian; in which I show that nothing is so effectual for the refutation of the Donatists, and for shutting their mouths directly from upholding their schism against the Catholic Church, as the letters and act of Cyprian.

Extract from Augustine's "Retractations," Book II. Chap. 67, On the Following Treatise, De Correptione et Gratia. I Wrote again to the same persons another treatise, which I entitled On Rebuke and Grace, because I had been told that some one there had said that no man ought to be rebuked for not doing God's commandments, but that prayer only should be made on his behalf, that he may do them. This book begins on this wise, "I have read your letters, dearly beloved brother Valentine."

Extract from Augustine's Retractions (Book II, Chapter 42): At that time also there came into my hands a certain book of Pelagius', in which he defends, with all the argumentative skill he could muster, the nature of man, in opposition to the grace of God whereby the unrighteous is justified and we become Christians. The treatise which contains my reply to him, and in which I defend grace, not indeed as in opposition to nature, but as that which liberates and controls nature, I have entitled On Nature and Grace. In this work sundry short passages, which were quoted by Pelagius as the words of the Roman bishop and martyr, Xystus, were vindicated by myself as if they really were the words of this Sixtus. For this I thought them at the time; but I afterwards discovered, that Sextus the heathen philosopher, and not Xystus the Christian bishop, was their author. This treatise of mine begins with the words: 'The book which you sent me.'"

The author praises Gratian’s zeal for instruction in the Faith, and speaks lowly of his own merits. Taught of God Himself, the Emperor stands in no need of human instruction; yet this his devoutness prepares the way to victory. The task appointed to the author is difficult: in the accomplishment whereof he will be guided not so much by reason and argument as by authority, especially that of the Nicene Council.

The person to whom I had addressed the three books entitled De Peccatorum Meritis et Remissione, in which I carefully discussed also the baptism of infants, informed me, when acknowledging my communication, that he was much disturbed because I declared it to be possible that a man might be without sin, if he wanted not the will, by the help of God, although no man either had lived, was living, or would live in this life so perfect in righteousness. He asked how I could say that it was possible of which no example could be adduced. Owing to this inquiry on the part of this person, I wrote the treatise entitled De Spiritu et Littera, in which I considered at large the apostle's statement, "The letter kills, but the spirit gives life." In this work, so far as God enabled me, I earnestly disputed with those who oppose that grace of God which justifies the servances of the Jews, who abstain from sundry meats and drinks in accordance with their ancient law, I mentioned the "ceremonies of certain meats" [quarumdam escarum cerimoniæ] - a phrase which, though not used in Holy Scriptures, seemed to me very convenient, because I remembered that cerimoniæ is tantamount to carimoniæ, as if from carere, to be without, and expresses the abstinence of the worshippers from certain things. If however, there is any other derivation of the word, which is inconsistent with the true religion, I meant no refernce whatever to it; I confined my use to the sense above indicated. This work of mine begins thus: "After reading the short treatise which I lately drew up for you, my beloved son Marcellinus," etc.

"As the psalms are a microcosm of the Old Testament, so the Expositions of the Psalms can be seen as a microcosm of Augustinian thought. In the Book of Psalms are to be found the history of the people of Israel, the theology and spirituality of the Old Covenant, and a treasury of human experience expressed in prayer and poetry. So too does the work of expounding the psalms recapitulate and focus the experiences of Augustine's personal life, his theological reflections and his pastoral concerns as Bishop of Hippo."--Publisher's website.
