Romans 4:5

For that investigation, which accords with faith, which builds, on the foundation of faith, the august knowledge of the truth, we know to be the best. Now we know that neither things which are clear are made subjects of investigation, such as if it is day, while it is day; nor things unknown, and never destined to become clear, as whether the stars are even or odd in number; nor things convertible; and those are so which can be said equally by those who take the opposite side, as if what is in the womb is a living creature or not. A fourth mode is, when, from either side of those, there is advanced an unanswerable and irrefragable argument. If, then, the ground of inquiry, according to all of these modes, is removed, faith is established. …

2. And from Thee, O Lord, unto whose eyes the depths of man’s conscience are naked, what in me could be hidden though I were unwilling to confess to Thee? For so should I hide Thee from myself, not myself from Thee. But now, because my groaning witnesseth that I am dissatisfied with myself, Thou shinest forth, and satisfiest, and art beloved and desired; that I may blush for myself, and renounce myself, and choose Thee, and may neither please Thee nor myself, except in Thee. To Thee, then, O Lord, am I manifest, whatever I am, and with what fruit I may confess unto Thee I have spoken. Nor do I it with words and sounds of the flesh, but with the words of the soul, and that cry of reflection which Thine ear knoweth. …

49. We have also examined what Thou willedst to be shadowed forth, whether by the creation, or the description of things in such an order. And we have seen that things severally are good, and all things very good, in Thy Word, in Thine Only-Begotten, both heaven and earth, the Head and the body of the Church, in Thy predestination before all times, without morning and evening. But when Thou didst begin to execute in time the things predestinated, that Thou mightest make manifest things hidden, and adjust our disorders (for our sins were over us, and we had sunk into profound darkness away from thee, and Thy good Spirit was borne over us to help us in due season), Thou didst both justify the ungodly, and didst divide them from the wicked; and madest firm the authority of Thy Book between those above, who would be docile unto Thee, and those under, who would be subject unto them; and Thou …

24. According to the form of God, it is said “Before all the hills He begat me,” that is, before all the loftinesses of things created and, “Before the dawn I begat Thee,” that is, before all times and temporal things: but according to the form of a servant, it is said, “The Lord created me in the beginning of His ways.” Because, according to the form of God, He said, “I am the truth;” and according to the form of a servant, “I am the way.” For, because He Himself, being the first-begotten of the dead, made a passage to the kingdom of God to life eternal for His Church, to which He is so the Head as to make the body also immortal, therefore He was “created in the beginning of the ways” of God in His work. …

5. But for our present need we must discuss, so far as God gives us power, in what manner the single of our Lord and Saviour Jesus Christ answers to, and is, so to say, in harmony with our double to the effect of salvation. We certainly, as no Christian doubts, are dead both in soul and body: in soul, because of sin; in body, because of the punishment of sin, and through this also in body because of sin. And to both these parts of ourselves, that is, both to soul and to body, there was need both of a medicine and of resurrection, that what had been changed for the worse might be renewed for the better. Now the death of the soul is ungodliness, and the death of the body is corruptibility, through which comes also a departure of the soul from the body. …

Chapter 5. 6. We ask, therefore, since he says, "He who receives faith from the faithless receives not faith, but guilt," and immediately adds to this the further statement, that "everything consists of an origin and root; and if it have not something for a head, it is nothing;"we ask, I say, in a case where the faithlessness of the baptizer is undetected: If then, the man whom he baptizes receives faith, and not guilt; if, then, the baptizer is not his origin and root and head, who is it from whom he receives faith? where is the origin from which he springs? where is the root of which he is a shoot? where the head which is his starting-point? Can it be, that when he who is baptized is unaware of the faithlessness of his baptizer, it is then Christ who gives faith, it is then Christ who is the origin and root and head? Alas for human rashness and conceit! Why do you not allow that it is …

Chapter 7. 8. But if it is perfect madness to hold such a view (for it is Christ always that justifieth the ungodly, by changing his ungodliness into Christianity; it is from Christ always that faith is received, Christ is always the origin of the regenerate and the head of the Church), what weight, then, will those words have, which thoughtless readers value by their sound, without inquiring what their inner meaning is? For the man who does not content himself with hearing the words with his ear, but considers the meaning of the phrase, when he hears, "What we look to is the conscience of the giver, that it may cleanse the conscience of the recipient," will answer, The conscience of man is often unknown to me, but I am certain of the mercy of Christ: when he hears, "He who receives faith from the faithless receives not faith, but guilt," will answer, Christ is not faithless, from whom I …

9. Augustin answered: Christ is not faithless, from whom the faithful man receives not guilt but faith. For he believeth on Him that justifieth the ungodly, that his faith may be counted for righteousness.

35. Augustin answered: Their throat is an open sepulchre, whence they breathe out death by lies. For "the mouth that belieth slayeth the soul." But if nothing is more true than that which Christ said, that His Church should be throughout all nations, beginning at Jerusalem, then there is nothing more false than that which you say, that it is in the party of Donatus. But the tongues which have deceived are the tongues of those who, whilst they are acquainted with their own deeds, not only say that they are just men, but that they are justifiers of men, which is said of One only "that justifieth the ungodly," and that because "He is just and the justifier." As regards the poison of asps, and the mouth full of cursing and bitterness, we have said enough already. …

Chapter 36. 42. But after this, when Petilianus came to that objection of ours, that they allowed the baptism of the followers of Maximianus, whom they had condemned, although in the statement of this question he thought it right to use his own words rather than mine; for neither do we assert that the baptism of sinners is of profit to us, seeing that we maintain it to belong not only to no sinners, but to no men whatsoever, in that we are satisfied that it is Christ’s alone, having put the question in this form, he says, "Yet you obstinately aver that it is right that the baptism of sinners should be of profit to you, because we too, according to your statement, maintained the baptism of criminals whom we justly condemned." When he came to this question, as I said before, even all the show of fight which he had made deserted him. …

Chapter 42. 51. For what I just now said is put with the greatest clearness in that very epistle of mine, in answering which he has said nothing; and I would beg of you to listen for a few moments to what he there has done. And although you are partisans of his, and hate us, yet, if you can, bear it with equanimity. For in his former epistle, to the first portion of which, the only portion which had then come into our hands, I had in the first instance made my reply, he had so rested the hope that is found in baptism in the baptizer, as to say, "For everything consists of an origin and root; and if anything has not a head, it is nothing." Since then Petilianus had said this, not wishing anything to be understood by the origin and root and head of baptizing a man, except the man by whom he might be baptized, I made a comment, and said "We ask, therefore, in a case where the faithlessness …

Chapter 49. 59. Do not therefore any longer say, "The conscience of one that gives in holiness is what we look for to cleanse the conscience of the recipient," lest you be asked, When a stain on the conscience of the giver is concealed, who cleanses the conscience of the recipient? And when you shall have answered, Either God or an angel (since there is no other answer which you possibly can make), then should follow a consequence whereby you would be confounded: Those then are justified with greater holiness who are baptized by undetected evil men, so as to be cleansed by God or by an angel, than those who are baptized by men who are genuinely and manifestly good, who cannot be compared with God or with the angels. …
