These books were written late in 420, or early in 421, and Alypius appears to have conveyed them to Italy during the latter year. Before its close, Augustin, having obtained and read the whole of Julian's attack on the first book of his work On Marriage and Concupiscence, wrote out a complete answer to it, [125] --a task that he was all the more anxious to complete, on perceiving that the extracts sent by Valerius were not only all from the first book of Julian's treatise, but were somewhat altered in the extracting. The resulting work, Against Julian, one of the longest that he wrote in the whole course of the Pelagian controversy, shows its author at his best: according to Cardinal Noris's judgment, he appears in it "almost divine," and Augustin himself clearly set great store by it. In the first book of this noble treatise, after professing his continued love for Julian, "whom he was unable not to love, whatever he [Julian] should say against him" (35), he undertakes to show that in affixing the opprobrious name of Manicheans on those who assert original sin, Julian is incriminating many of the most famous fathers, both of the Latin and Greek Churches. In proof of this, he makes appropriate quotations from Irenæus, Cyprian, Reticius, Olympius, Hilary, Ambrose, Gregory Nazianzenus, Basil, John of Constantinople. [126] Then he argues, that, so far from the catholics falling into Manichean heresy, Julian plays, himself, into the hands of the Manicheans in their strife against the catholics, by many unguarded statements, such as, e.g., when he says that an evil thing cannot arise from what is good, that the work of the Devil cannot be suffered to be diffused by means of a work of God, that a root of evil cannot be placed within a gift of God, and the like. The second book advances to greater detail, and adduces the five great arguments which the Pelagians urged against the catholics, in order to test them by the voice of antiquity. These arguments are stated as follows (2): "For you say, That we, by asserting original sin, affirm that the Devil is the maker of infants, condemn marriage, deny that all sins are remitted in baptism, accuse God of the guilt of sin, and produce despair of perfection.' You contend that all these are consequences, if we believe that infants are born bound by the sin of the first man, and are therefore under the Devil unless they are born again in Christ. For, It is the Devil that creates,' you say, if they are created from that wound which the Devil inflicted on the human nature that was made at first.' And marriage is condemned,' you say, if it is to be believed to have something about it whence it produces those worthy of condemnation.' And all sins are not remitted in baptism,' you say, if there remains any evil in baptized couples whence evil offspring are produced.' And how is God,' you ask, not unjust, if He, while remitting their own sins to baptized persons, yet condemns their offspring, inasmuch as, although it is created by Him, it yet ignorantly and involuntarily contracts the sins of others from those very parents to whom they are remitted?' Nor can men believe,' you add, that virtue--to which corruption is to be understood to be contrary--can be perfected, if they cannot believe that it can destroy the inbred vices, although, no doubt, these can scarcely be considered vices, since he does not sin, who is unable to be other than he was created.'" These arguments are then tested, one by one, by the authority of the earlier teachers who were appealed to in the first book, and shown to be condemned by them. The remaining four books follow Julian's four books, argument by argument, refuting him in detail. In the third book it is urged that although God is good, and made man good, and instituted marriage which is, therefore, good, nevertheless concupiscence is evil, and in it the flesh lusts against the spirit. Although chaste spouses use this evil well, continent believers do better in not using it at all. It is pointed out, how far all this is from the madness of the Manicheans, who dream of matter as essentially evil and co-eternal with God; and shown that evil concupiscence sprang from Adam's disobedience and, being transmitted to us, can be removed only by Christ. It is shown, also, that Julian himself confesses lust to be evil, inasmuch as he speaks of remedies against it, wishes it to be bridled, and speaks of the continent waging a glorious warfare. The fourth book follows the second book of Julian's work, and makes two chief contentions: that unbelievers have no true virtues, and that even the heathen recognize concupiscence as evil. It also argues that grace is not given according to merit, and yet is not to be confounded with fate; and explains the text that asserts that God wishes all men to be saved,' in the sense that all men' means all that are to be saved' since none are saved except by His will. [127] The fifth book, in like manner, follows Julian's third book, and treats of such subjects as these: that it is due to sin that any infants are lost; that shame arose in our first parents through sin; that sin can well be the punishment of preceding sin; that concupiscence is always evil, even in those who do not assent to it; that true marriage may exist without intercourse; that the "flesh" of Christ differs from the "sinful flesh" of other men; and the like. In the sixth book, Julian's fourth book is followed, and original sin is proved from the baptism of infants, the teaching of the apostles, and the rites of exorcism and exsufflation incorporated in the form of baptism. Then, by the help of the illustration drawn from the olive and the oleaster, it is explained how Christian parents can produce unregenerate offspring; and the originally voluntary character of sin is asserted, even though it now comes by inheritance.
After the completion of this important work, there succeeded a lull in the controversy, of some years duration; and the calm refutation of Pelagianism and exposition of Christian grace, which Augustin gave in his Enchiridion, [128] might well have seemed to him his closing word on this all-absorbing subject. But he had not yet given the world all he had in treasure for it, and we can rejoice in the chance that five or six years afterwards drew from him a renewed discussion of some of the more important aspects of the doctrine of grace. The circumstances which brought this about are sufficiently interesting in themselves, and open up to us an unwonted view into the monastic life of the times. There was an important monastery at Adrumetum, the metropolitan city of the province of Byzacium, [129] from which a monk named Florus went out on a journey of charity to his native country of Uzalis about 426. On the journey he met with Augustin's letter to Sixtus, [130] in which the doctrines of gratuitous and prevenient grace were expounded. He was much delighted with it, and, procuring a copy, sent it back to his monastery for the edification of his brethren, while he himself went on to Carthage. At the monastery, the letter created great disturbance: without the knowledge of the abbot, Valentinus, it was read aloud to the monks, many of whom were unskilled in theological questions; and some five or more were greatly offended, and declared that free will was destroyed by it. A secret strife arose among the brethren, some taking extreme grounds on both sides. Of all this, Valentinus remained ignorant until the return of Florus, who was attacked as the author of all the trouble, and who felt it his duty to inform the abbot of the state of affairs. Valentinus applied first to the bishop, Evodius, for such instruction as would make Augustin's letter clear to the most simple. Evodius replied, praising their zeal and deprecating their contentiousness, and explaining that Adam had full free will, but that it is now wounded and weak, and Christ's mission was as a physician to cure and recuperate it. "Let them read," is his prescription, "the words of God's elders....And when they do not understand, let them not quickly reprehend, but pray to understand." This did not, however, cure the malecontents, and the holy presbyter Sabrinus was appealed to, and sent a book with clear interpretations. But neither was this satisfactory; and Valentinus, at last, reluctantly consented that Augustin himself should be consulted,--fearing, he says, lest by making inquiries he should seem to waver about the truth. Two members of the community were consequently permitted to journey to Hippo, but they took with them no introduction and no commendation from their abbot. Augustin, nevertheless, received them without hesitation, as they bore themselves with too great simplicity to allow him to suspect them of deception. Now we get a glimpse of life in the great bishop's monastic home. The monks told their story, and were listened to with courtesy and instructed with patience; and, as they were anxious to get home before Easter, they received a letter for Valentinus [131] in which Augustin briefly explains the nature of the misapprehension that had arisen, and points out that both grace and free will must be defended, and neither so exaggerated as to deny the other. The letter of Sixtus, he explains, was written against the Pelagians, who assert that grace is given according to merit, and briefly expounds the true doctrine of grace as necessarily gratuitous and therefore prevenient. When the monks were on the point of starting home, they were joined by a third companion from Adrumetum, and were led to prolong their visit. This gave him the opportunity he craved for their fuller instruction: he read with them and explained to them not only his letter to Sixtus, from which the strife had risen, but much of the chief literature of the Pelagian controversy, [132] copies of which also were made for them to take home with them; and when they were ready to go, he sent by them another and longer letter to Valentinus, and placed in their hands a treatise composed for their especial use, which, moreover, he explained to them. This longer letter is essentially an exhortation "to turn aside neither to the right hand nor to the left,"--neither to the left hand of the Pelagian error of upholding free will in such a manner as to deny grace, nor to the right hand of the equal error of so upholding grace as if we might yield ourselves to evil with impunity. Both grace and free will are to be proclaimed; and it is true both that grace is not given to merits, and that we are to be judged at the last day according to our works. The treatise which Augustin composed for a fuller exposition of these doctrines is the important work On Grace and Free Will. After a brief introduction, explaining the occasion of his writing, and exhorting the monks to humility and teachableness before God's revelations (1), Augustin begins by asserting and proving the two propositions that the Scriptures clearly teach that man has free will (2-5), and, as clearly, the necessity of grace for doing any good (6-9). He then examines the passages which the Pelagians claim as teaching that we must first turn to God, before He visits us with His grace (10-11), and then undertakes to show that grace is not given to merit (12 sq.), appealing especially to Paul's teaching and example, and replying to the assertion that forgiveness is the only grace that is not given according to our merits (15-18), and to the query, "How can eternal life be both of grace and of reward?" (19-21). The nature of grace, what it is, is next explained (22 sq.). It is not the law, which gives only knowledge of sin (22-24), nor nature, which would render Christ's death needless (25), nor mere forgiveness of sins, as the Lord's Prayer (which should be read with Cyprian's comments on it) is enough to show (26). Nor will it do to say that it is given to the merit of a good will, thus distinguishing the good work which is of grace from the good will which precedes grace (27-30); for the Scriptures oppose this, and our prayers for others prove that we expect God to be the first mover, as indeed both Scripture and experience prove that He is. It is next shown that both free will and grace are concerned in the heart's conversion (31-32), and that love is the spring of all good in man (33-40), which, however, we have only because God first loved us (38), and which is certainly greater than knowledge, although the Pelagians admit only the latter to be from God (40). God's sovereign government of men's wills is then proved from Scripture (41-43), and the wholly gratuitous character of grace is illustrated (44), while the only possible theodicy is found in the certainty that the Lord of all the earth will do right. For, though no one knows why He takes one and leaves another, we all know that He hardens judicially and saves graciously,--that He hardens none who do not deserve hardening, but none that He saves deserve to be saved (45). The treatise closes with an exhortation to its prayerful and repeated study (46).
