Preliminary notes
(1) From the Preface of Augustine’s Unfinished Work Against Julianus.
I Wrote a treatise, under the title On Marriage and Concupiscence, and addressed it to the Count Valerius, on learning that he had been informed of the Pelagians that they charge us with condemning marriage. Now in that treatise I showed the distinction, as criticially and accurately as I was able, between the good of marriage and the evil of carnal concupiscence, — an evil which is well used by conjugal chastity. On receiving my treatise, the illustrious man whom I have named sent me in a short paper a few sentences culled from a work of Julianus, a Pelagian heretic. In this work he has thought fit to extend to four books his answer to the before-mentioned treatise of mine, which is limited to one book only, On Marriage and Concupiscence. I do not know to whom we were indebted for the said extracts: he confined his selection, evidently on purpose, to the first book of Julianus’ work. At the request of Valerius, I lost no time in drawing up my answer to the extracts. And thus it happened that I have written a second book also under the same title; and in reply to this Julianus has drawn up to eight books, in excess of his loquacious powers.
(2) From Augustine’s Epistle to Claudius [CCVII.].
Whoever has perused this second book of mine, addressed (as the first was) to the Count Valerius, and drawn up (as, indeed, both were) for his use, will have discovered that there are some points in which I have not answered Julianus, but that I meant my work rather for him who made the extracts from that writer’s books, and who did not arrange them in the order in which he found them. He deemed some considerable alteration necessary in his arrangement, very probably with the view of appropriating by this method as his own the thoughts which evidently were another person’s.
The book itself
Augustine, in this latter book, refutes sundry sentences which had been culled by some unknown author from the first of four books that Julianus had published in opposition to the former book of his treatise On Marriage and Concupiscence; which sentences had been forwarded to him at the instance of the Count Valerius. He vindicates the Catholic doctrine of original sin from his opponent’s cavils and subtleties, and particularly shows how diverse it is from the infamous heresy of the Manicheans.
Chapter 1 [I.]— Introductory Statement.
I Cannot tell you, dearly loved and honoured son Valerius, how great is the pleasure which my heart receives when I hear of your warm and earnest interest in the testimony of the word of God against the heretics; and this, too, amidst your military duties and the cares which devolve on you in the eminent position you so justly occupy, and the pressing functions, moreover, of your political life. After reading the letter of your Eminence, in which you acknowledge the book which I dedicated to you, I was roused to write this also; for you request me to attend to the statement, which my brother and fellow bishop Alypius is commissioned to make to me, about the discussion which is being raised by the heretics over sundry passages of my book. Not only have I received this information from the narrative of my said brother, but I have also read the extracts which he produced, and which you had yourself forwarded to Rome, after his departure from Ravenna. On discovering the boastful language of our adversaries, as I could easily do in these extracts, I determined, with the help of the Lord, to reply to their taunts with all the truthfulness and scriptural authority that I could command.
Chapter 2 [II.]— In This and the Four Next Chapters He Adduces the Garbled Extracts He Has to Consider.
The paper which I now answer starts with this title: Headings out of a book written by Augustine, in reply to which I have culled a few passages out of books. I perceive from this that the person who forwarded these written papers to your Excellency wanted to make his extracts out of the books he does not name, with a view, so far as I can judge, to getting a quicker answer, in order that he might not delay your urgency. Now, after considering what books they were which he meant, I suppose that it must have been those which Julianus mentioned in the Epistle he sent to Rome, a copy of which found its way to me at the same time. For he there says: They go so far as to allege that marriage, now in dispute, was not instituted by God — a declaration which may be read in a work of Augustine’s, to which I have lately replied in a treatise of four books. These are the books, as I believe, from which the extracts were taken. It would, then, have been perhaps the better course if I had set myself deliberately to disprove and refute that entire work of his, which he spread out into four volumes. But I was most unwilling to delay my answer, even as you yourself lost no time in forwarding to me the written statements which I was requested to reply to.
