Augustin was not less busy with his pen, during these months, than with his voice. Quite a series of letters belong to the last half of 418, in which he argues to his distant correspondents on the same themes which he was so iterantly trying to make clear to his Carthaginian auditors. One of the most interesting of these was written to a fellow-bishop, Optatus, on the origin of the soul. [107] Optatus, like Jerome, had expressed himself as favoring the theory of a special creation of each at birth; and Augustin, in this letter as in the paper sent to Jerome, lays great stress on so holding our theories on so obscure a matter as to conform to the indubitable fact of the transmission of sin. This fact, such passages as 1 Cor. xv. 21 sq., Rom. v. 12 sq., make certain; and in stating this, Augustin takes the opportunity to outline the chief contents of the catholic faith over against the Pelagian denial of original sin and grace: that all are born under the contagion of death and in the bond of guilt; that there is no deliverance except in the one Mediator, Christ Jesus; that before His coming men received him as promised, now as already come, but with the same faith; that the law was not intended to save, but to shut up under sin and so force us back upon the one Saviour; and that the distribution of grace is sovereign. Augustin pries into God's sovereign counsels somewhat more freely here than is usual with him. "But why those also are created who, the Creator foreknew, would belong to damnation, not to grace, the blessed apostle mentions with as much succinct brevity as great authority. For he says that God, wishing to show His wrath and demonstrate His power,' etc. (Rom. ix. 22). Justly, however, would he seem unjust in forming vessels of wrath for perdition, if the whole mass from Adam were not condemned. That, therefore, they are made on birth vessels of anger, belongs to the punishment due to them; but that they are made by re-birth vessels of mercy, belongs to the grace that is not due to them. God, therefore, shows his wrath,--not, of course, perturbation of mind, such as is called wrath among men, but a just and fixed vengeance....He shows also his power, by which he makes a good use of evil men, and endows them with many natural and temporal goods, and bends their evil to admonition and instruction of the good by comparison with it, so that these may learn from them to give thanks to God that they have been made to differ from them, not by their own deserts which were of like kind in the same mass, but by His pity....But by creating so many to be born who, He foreknew, would not belong to his grace, so that they are more by an incomparable multitude than those whom he deigned to predestinate as children of the promise into the glory of His Kingdom,--He wished to show by this very multitude of the rejected how entirely of no moment it is to the just God what is the multitude of those most justly condemned. And that hence also those who are redeemed from this condemnation may understand, that what they see rendered to so great a part of the mass was the due of the whole of it,--not only of those who add many others to original sin, by the choice of an evil will, but as well of so many children who are snatched from this life without the grace of the Mediator, bound by no bond except that of original sin alone." With respect to the question more immediately concerning which the letter was written, Augustin explains that he is willing to accept the opinion that souls are created for men as they are born, if only it can be made plain that it is consistent with the original sin that the Scriptures so clearly teach. In the paper sent to Jerome, the difficulties of creationism are sufficiently urged; this letter is interesting on account of its statement of some of the difficulties of traducianism also,--thus evidencing Augustin's clear view of the peculiar complexity of the problem, and justifying his attitude of balance and uncertainty between the two theories. The human understanding,' he says, can scarcely comprehend how a soul arises from a parent's soul in the offspring; or is transmitted to the offspring as a candle is lighted from a candle and thence another fire comes into existence without loss to the former one. Is there an incorporeal seed for the soul, which passes, by some hidden and invisible channel of its own, from the father to the mother, when it is conceived in the woman? Or, even more incredible, does it lie enfolded and hidden within the corporeal seed?' He is lost in wonder over the question whether, when conception does not take place, the immortal seed of an immortal soul perishes; or, does the immortality attach itself to it only when it lives? He even expresses the doubt whether traducianism will explain what it is called in to explain, much better than creationism; in any case, who denies that God is the maker of every soul? Isaiah (lvii. 16) says, "I have made every breath;" and the only question that can arise is as to method,--whether He "makes every breath from the one first breath, just as He makes every body of man from the one first body; or whether he makes new bodies indeed, from the one body, but new souls out of nothing." Certainly nothing but Scripture can determine such a question; but where do the Scriptures speak unambiguously upon it? The passages to which the creationists point only affirm the admitted fact that God makes the soul; and the traducianists forget that the word "soul" in the Scriptures is ambiguous, and can mean "man," and even a "dead man." What more can be done, then, than to assert what is certain, viz., that sin is propagated, and leave what is uncertain in the doubt in which God has chosen to place it?
This letter was written not long after the issue of Zosimus' Tractoria, demanding the signature of all to African orthodoxy; and Augustin sends Optatus "copies of the recent letters which have been sent forth from the Roman see, whether specially to the African bishops or generally to all bishops," on the Pelagian controversy, "lest perchance they had not yet reached" his correspondent, who, it is very evident, he was anxious should thoroughly realize "that the authors, or certainly the most energetic and noted teachers," of these new heresies, "had been condemned in the whole Christian world by the vigilance of episcopal councils aided by the Saviour who keeps His Church, as well as by two venerable overseers of the Apostolical see, Pope Innocent and Pope Zosimus, unless they should show repentance by being convinced and reformed." To this zeal we owe it that the letter contains an extract from Zosimus' Tractoria, one of the two brief fragments of that document that have reached our day.
There was another ecclesiastic in Rome, besides Zosimus, who was strongly suspected of favoring the Pelagians,--the presbyter Sixtus, who afterwards became Pope Sixtus III. But when Zosimus sent forth his condemnation of Pelagianism, Sixtus sent also a short letter to Africa addressed to Aurelius of Carthage, which, though brief, indicated a considerable vigor against the heresy which he was commonly believed to have before defended, [108] and which claimed him as its own. [109] Some months afterwards, he sent another similar, but longer, letter to Augustin and Alypius, more fully expounding his rejection of "the fatal dogma" of Pelagius, and his acceptance of "that grace of God freely given by Him to small and great, to which Pelagius' dogma was diametrically opposed." Augustin was overjoyed with these developments. He quickly replied in a short letter [110] in which he expresses the delight he has in learning from Sixtus' own hand that he is not a defender of Pelagius, but a preacher of grace. And close upon the heels of this he sent another much longer letter, [111] in which he discusses the subtler arguments of the Pelagians with an anxious care that seems to bear witness to his desire to confirm and support his correspondent in his new opinions. Both letters testify to Augustin's approval of the persecuting measures which had been instituted by the Roman see in obedience to the emperor; and urge on Sixtus his duty not only to bring the open heretics to deserved punishment, but to track out those who spread their poison secretly, and even to remember those whom he had formerly heard announcing the error before it had been condemned, and who were now silent through fear, and to bring them either to open recantation of their former beliefs, or to punishment. It is pleasanter to recall our thoughts to the dialectic of these letters. The greater part of the second is given to a discussion of the gratuitousness of grace, which, just because grace, is given to no preceding merits. Many subtle objections to this doctrine were brought forward by the Pelagians. They said that "free will was taken away if we asserted that man did not have even a good will without the aid of God;" that we made "God an accepter of persons, if we believed that without any preceding merits He had mercy on whom He would, and whom He would He called, and whom He would He made religious;" that "it was unjust, in one and the same case, to deliver one and punish another;" that, if such a doctrine is preached, "men who do not wish to live rightly and faithfully, will excuse themselves by saying that they have done nothing evil by living ill, since they have not received the grace by which they might live well;" that it is a puzzle "how sin can pass over to the children of the faithful, when it has been remitted to the parents in baptism;" that "children respond truly by the mouth of their sponsors that they believe in remission of sins, but not because sins are remitted to them, but because they believe that sins are remitted in the church or in baptism to those in whom they are found, not to those in whom they do not exist," and consequently they said that "they were unwilling that infants should be so baptized unto remission of sins as if this remission took place in them," for (they contend) "they have no sin; but they are to be baptized, although without sin, with the same rite of baptism through which remission of sins takes place in any that are sinners." This last objection is especially interesting [112] because it furnishes us with the reply which the Pelagians made to the argument that Augustin so strongly pressed against them from the very act and ritual of baptism, as implying remission of sins. [113] His rejoinder to it here is to point to the other parts of the same ritual, and to ask why, then, infants are exorcised and exsufflated in baptism. "For, it cannot be doubted that this is done fictitiously, if the Devil does not rule over them; but if he rules over them, and they are therefore not falsely exorcised and exsufflated, why does that prince of sinners rule over them except because of sin?" On the fundamental matter of the gratuitousness of grace, this letter is very explicit. "If we seek for the deserving of hardening, we shall find it....But if we seek for the deserving of pity, we shall not find it; for there is none, lest grace be made a vanity if it is not given gratis, but rendered to merits. But, should we say that faith preceded and in it there is desert of grace, what desert did man have before faith that he should receive faith? For, what did he have that he did not receive? and if he received it, why does he glory as if he received it not? For as man would not have wisdom, understanding, prudence, fortitude, knowledge, piety, fear of God, unless he had received (according to the prophet) the spirit of wisdom and understanding, of prudence and fortitude, of knowledge and piety and the fear of God; as he would not have justice, love, continence, except the spirit was received of whom the apostle says, For you did not receive the spirit of fear, but of virtue, and love, and continence:' so he would not have faith unless he received the spirit of faith of whom the same apostle says, Having then the same spirit of faith, according to what is written, "I believed and therefore spoke," we too believe and therefore speak.' But that He is not received by desert, but by His mercy who has mercy on whom He will, is manifestly shown where he says of himself, I have obtained mercy to be faithful.'" "If we should say that the merit of prayer precedes, that the gift of grace may follow,...even prayer itself is found among the gifts of grace" (Rom. viii. 26). "It remains, then, that faith itself, whence all righteousness takes beginning;...it remains, I say, that even faith itself is not to be attributed to the human will which they extol, nor to any preceding merits, since from it begin whatever good things are merits: but it is to be confessed to be the gratuitous gift of God, since we consider it true grace, that is, without merits, inasmuch as we read in the same epistle, God divides out the measure of faith to each' (Rom. xii. 3). Now, good works are done by man, but faith is wrought in man, and without it these are not done by any man. For all that is not of faith is sin" (Rom. xiv. 23).
