71 Translator’s Introductory Notice. ———————————— In the remarkable work known as his Retractations, Augustin makes a brief statement on the subject of this treatise on the Harmony of the Evangelists. The sixteenth chapter of the second book of that memorable review of his literary career, contains corrections of certain points on which he believed that he had not been sufficiently accurate in these dis- cussions. In the same passage he informs us that this treatise was undertaken during the years in which he was occupied with his great work on the Trinity, and that, breaking in upon the task which had been making gradual progress under his hand, he wrought continu- ously at this new venture until it was finished. Its composition is assigned to about the year 400 A.D. The date is determined in the following manner: In the first book there is a sentence (§ 27) which appears to indicate that, by the time when Augustin engaged himself with this effort, the destruction of the idols of the old religion was being carried out under express imperial authority. No law of that kind, however, affecting Africa, seems to be found ex- pressed previous to those to which he refers at the close of the eighteenth book of the City of God. There he gives us to understand that such measures were put in force in Carthage, under Gaudentius and Jovius, the associates of the Emperor Honorius, and states that for the space of nearly thirty years from that time the Christian religion made advances large enough to arrest general attention. Before that period, which must have been about the year 399, the idols could not be destroyed, as Augustin elsewhere indicates (Serm. lxii. 11, n. 17), but with the consent of the parties to whom they belonged. These considerations are taken to fix the composition of this work to a date not earlier than the close of 399 A.D. Among Augustin’s numerous theological productions, this one takes rank with the most toilsome and exhaustive. We find him expressing himself to that effect now and again, when he has occasion to allude to it. Thus, in the 112th Tractate on John (n. i), he calls it a labor- ious piece of literature; and in the 117th Tractate on the same evangelist, he speaks of the themes here dealt with as matters which were discussed with the utmost painstaking. Its great object is to vindicate the Gospel against the critical assaults of the heathen. Paganism, having tried persecution as its first weapon, and seen it fail, attempted next to discredit the new faith by slandering its doctrine, impeaching its history, and attacking with special persistency the veracity of the Gospel writers. In this it was aided by some of Au- gustin’s heretical antagonists, who endeavoured at times to establish a conspicuous incon- sistency between the Jewish Scriptures and the Christian, and at times to prove the several sections of the New Testament to be at variance with each other. Many alleged that the ori- ginal Gospels had received considerable additions of a spurious character. And it was a fa- vorite method of argumentation, adopted both by heathen and by Manichæan adversaries, to urge that the evangelical historians contradicted each other. Thus, in the present treatise (i. 7), Augustin speaks of this matter of the discrepancies between the Evangelists as the Translator’s Introductory Notice. 160 Translator’s Introductory Notice.
