The intellectual interests of these four years are more easily determined, principally concerned as they are with the Manichean controversy, and producing the treatises De utilitate credendi (391), De duabus animabus contra Manichaos (first half of 392), and Contra Adimantum (394 or 395).His activity against the Donatists also begins in this period, but he is still more occupied with the Manicheans, both from the recollections of his own past and from his increasing knowledge of Scripture, which appears, together with a stronger hold on the Church's teaching, in the works just named, and even more in others of this period, such as his expositions of the Sermon on the Mount and of the Epistles to the Romans and the Galatians.
Entered into St. Paul's teaching
Full as the writings of this epoch are, however, of Biblical phrases and terms,-grace and the law, predestination, vocation, justification, regeneration-a reader who is thoroughly acquainted with Neoplatonism will detect Augustine's avid love of it in a Christian dress in not a few places. He has entered so far into St. Paul's teaching that humanity as a whole appears to him a massa peccati or peccatorum, which, if left to itself, that is, without the grace of God, must inevitably perish. However much we are here reminded of the later Augustine, it is clear that he still held the belief that the free will of man could decide his own destiny.
He knew some who saw in Romans ix an unconditional predestination which took away the freedom of the will; but he was still convinced that this was not the Church's teaching. His opinion on this point did not change till after he was a bishop.The more widely known Augustine became, the more Valerius, the bishop of Hippo, was afraid of losing him on the first vacancy of some neighboring see, and desired to fix him permanently in Hippo by making him coadjutor-bishop,-a desire in which the people ardently concurred. Augustine was strongly opposed to the project, though possibly neither he nor Valerius knew that it might be held to be a violation of the eighth canon of Niema, which forbade in its last clause " two bishops in one city ";
and the primate of Numidia, Megalius of Calama, seems to have raised difficulties which sprang at least partly from a personal lack of confidence. But Valerius carried his plan through, and not long before Christmas, 395, Augustine was consecrated by Megalius.It is not known when Valerius died; but it makes little difference, since for the rest of his life he left the administration more and more in the hands of his assistant. Space forbids any attempt to trace events of his later life; and in what remains to be said, biographical interest must be largely our guide.
Synods of Carthage
We know a considerable number of events in Augustine's episcopal life which can be surely placed-the so-called third and eighth synods of Carthage in 397 and 403, at which, as at those still to be mentioned, he was certainly present; the disputation with the Manichean Felix at Hippo in 404; the eleventh synod of Carthage in 407; the conference with the Donatists in Carthage, 411; the synod of Mileve, 416; the African general council at Carthage, 418; the journey to Caesarea in Mauretania and the disputation with the Donatist bishop there, 418; another general council in Carthage, 419; and finally the consecration of Eraclius as his assistant in 426.
Anti-Manicheanism and Pelagian Writings
His special and direct opposition to Manicheanism did not last a great while after his consecration. About 397 he wrote a tractate Contra epistolam [Manichcet] quam vocant fundamenti; in the De agone christiano, written about the same time, and in the Confessiones, a little later, numerous anti-Manichean expressions occur. After this, however, he only attacked the Manicheans on some special occasion, as when, about 400, on the request of his "brethren,"
he wrote a detailed rejoinder to Faustus, a Manichean bishop, or made the treatise De natura boni out of his discussions with Felix; a little later, also, the letter of the Manichean Secundinus gave him occasion to write Contra Secundinum, which, in spite of its comparative brevity, he regarded as the best of his writings on this subject. In the succeeding period, he was much more occupied with anti-Donatist polemics, which in their turn were forced to take second place by the emergence of the Pelagian controversy.
It has been thought that Augustine's anti-Pelagian teaching grew out of his conception of the Church and its sacraments as a means of salvation; and attention was called to the fact that before the Pelagian controversy this aspect of the Church had, through the struggle with the Donatists, assumed special importance in his mind. But this conception should be denied. It is quite true that in 395 Augustine's views on sin and grace, freedom and predestination, were not what they afterward came to be. But the new trend was given to them before the time of his anti-Donatist activity, and so before he could have heard anything of Pelagius.
Reactions against Augustine's views
What we call Augustinianism was not a reaction against Pelagianism; it would be much truer to say that the latter was a reaction against Augustine's views. He himself names the beginning of his episcopate as the turning-point. Accordingly, in the first thing which he wrote after his consecration, the De diversis gucestionibus ad Simplicianum (396 or 397), we come already upon the new conception. In no other of his writings do we see as plainly the gradual attainment of conviction on any point; as he himself says in the Retractationes, he was laboring for the free choice of the will of man, but the grace of God won the day.
So completely was it won, that we might set forth the specifically Augustinian teaching on grace, as against the Pelagians and the Massilians, by a series of quotations taken wholly from this treatise. It is true that much of his later teaching is still undeveloped here; the question of predestination (though the word is used) does not really come up; he is not clear as to the term " election"; and nothing is said of the " gift of perseverance." But what we get on these points later is nothing but the logical consequence of that which is expressed here, and so we have the actual genesis of Augustine's predestinarian teaching under our eyes. It is determined by no reference to the question of infant baptism -- still less by any considerations connected with the conception of the Church.
Impulse from Scripture
The impulse comes directly from Scripture, with the help, it is true, of those exegetical thoughts which he mentioned earlier as those of others and not his own. To be sure, Paul alone can not explain this doctrine of grace; this is evident from the fact that the very definition of grace is non-Pauline. Grace is for Augustine, both now and later, not the misericordia peccata condonans of the Reformers, as justification is not the alteration of the relation to God accomplished by means of the accipere remissionem. Grace is rather the misericordia which displays itself in the divine inspiratio and justification is justum or pium fieri as a result of this.
We may even say that this grace is an interne illuminatio such as a study of Augustine's Neoplatonism enables us easily to understand, which restores the connection with the divine bonum esse. He had long been convinced that " not only the greatest but also the smallest good things can not be, except from him from whom are all good things, that is, from God;" and it might well seem to him to follow from this that faith, which is certainly a good thing, could proceed from the operation of God alone. This explains the idea that grace works like a law of nature, drawing the human will to God with a divine omnipotence.
Of course this Neoplatonic coloring must not be exaggerated; it is more consistent with itself in his earlier writings than in the later, and he would never have arrived at his predestinarian teaching without the New Testament. With this knowledge, we are in a position to estimate the force of a difficulty which now confronted Augustine for the first time, but never afterward left him, and which has been present in the Roman Catholic teaching even down to the Councils of Trent and the Vatican. If faith depends upon an action of our own, solicited but not caused by vocation, it can only save a man when, per fidem gratiam accipiens, he becomes one who not merely believes in God but loves him also.
But if faith has been already inspired by grace, and if, while the Scripture speaks of justification by faith, it is held (in accordance with the definition of grace) that justification follows upon the infitsio caritatis, -then either the conception of the faith which is God-inspired must pass its fluctuating boundaries and, approach nearer to that of caritas, or the conception of faith which is unconnected with caritas will render the fact of its inspiration unintelligible and justification by faith impossible. Augustine's anti-Pelagian writings set forth this doctrine of grace more clearly in some points, such as the terms " election," " predestination," " the gift of perseverance," and also more logically; but space forbids us to show this here, as the part taken in this controversy by Augustine is so fully detailed elsewhere.
