Genesis 22:18

1. Hear, O Donatists, what the Catholic Church says to you: “O ye sons of men, how long will ye be slow of heart? why will ye love vanity, and follow after lies?” Why have you severed yourselves, by the heinous impiety of schism, from the unity of the whole world? You give heed to the falsehoods concerning the surrendering of the divine books to persecutors, which men who are either deceiving you, or are themselves deceived, utter in order that you may die in a state of heretical separation: and you do not give heed to what these divine books themselves proclaim, in order that you may live in the peace of the Catholic Church. Wherefore do you lend an open ear to the words of men who tell you things which they have never been able to prove, and are deaf to the voice of God speaking thus: “The Lord hath said unto me, Thou art My Son; this day have I begotten Thee. …

11. Finally, we beg you to send back such writings by our brethren whom we have sent to you. If, however, you will not do this, at least hear us as well as those of your own party, at whose hands we suffer such wrongs. Show us the truth for which you allege that you suffer persecution, at the time when we are suffering so great cruelties from your side. For if you convict us of being in error, perhaps you will concede to us an exemption from being rebaptized by you, because we were baptized by persons whom you have not condemned; and you granted this exemption to those whom Felicianus of Musti, and Prætextatus of Assuri, had baptized during the long period in which you were attempting to cast them out of their churches by legal interdicts, because they were in communion with Maximianus, along with whom they were condemned explicitly and by name in the Council of Bagæ. …

51. But, my brother, if you forbear seeking the empty honour which comes from men, and despise the reproach of fools, who will be ready to say, “Why do you now destroy what you once laboured to build up?” it seems to me to be beyond doubt that you will now pass over to the Church which I perceive that you acknowledge to be the true Church: the proofs of which sentiment on your part I find at hand. For in the beginning of your letter which I am now answering you have these words: “I knew you, my excellent friend, as a man devoted to peace and uprightness, when you were still far removed from the Christian faith, and were in these earlier days occupied with literary pursuits; but since your conversion at a more recent time to the Christian faith, you give your time and labour, as I am informed by the statements of many persons, to theological controversies.” These words are undoubtedly you …

This, then, is the universal way of the soul’s deliverance, the way that is granted by the divine compassion to the nations universally. And no nation to which the knowledge of it has already come, or may hereafter come, ought to demand, Why so soon? or, Why so late? for the design of Him who sends it is impenetrable by human capacity. This was felt by Porphyry when he confined himself to saying that this gift of God was not yet received, and had not yet come to his knowledge. For though this was so, he did not on that account pronounce that the way it self had no existence. …

But let us rather hear the divine words spoken through the angel. For the Scripture says, “And Abraham stretched forth his hand to take the knife, that he might slay his son. And the Angel of the Lord called unto him from heaven, and said, Abraham. And he said, Here am I. And he said, Lay not thine hand upon the lad, neither do thou anything unto him: for now I know that thou fearest God, and hast not spared thy beloved son for my sake.” It is said, “Now I know,” that is, Now I have made to be known; for God was not previously ignorant of this. Then, having offered up that ram instead of Isaac his son, “Abraham,” as we read, “called the name of that place The Lord seeth: as they say this day, In the mount the Lord hath appeared.” As it is said, “Now I know,” for Now I have made to be known, so here, “The Lord sees,” for The Lord hath appeared, that is, made Himself to be seen. …

But it may be replied, Who is this God, or what proof is there that He alone is worthy to receive sacrifice from the Romans? One must be very blind to be still asking who this God is. He is the God whose prophets predicted the things we see accomplished. He is the God from whom Abraham received the assurance, “In thy seed shall all nations be blessed.” That this was fulfilled in Christ, who according to the flesh sprang from that seed, is recognized, whether they will or no, even by those who have continued to be the enemies of this name. He is the God whose divine Spirit spake by the men whose predictions I cited in the preceding books, and which are fulfilled in the Church which has extended over all the world. …

In another place the same Daniel says, “And there shall be a time of trouble, such as was not since there was born a nation upon earth until that time: and in that time all Thy people which shall be found written in the book shall be delivered. And many of them that sleep in the mound of earth shall arise, some to everlasting life, and some to shame and everlasting confusion. And they that be wise shall shine as the brightness of the firmament; and many of the just as the stars for ever.” This passage is very similar to the one we have quoted from the Gospel, at least so far as regards the resurrection of dead bodies. …

Wherefore, not to mention many other instances besides, as we now see in Christ the fulfillment of that which God promised to Abraham when He said, “In thy seed shall all nations be blessed,” so this also shall be fulfilled which He promised to the same race, when He said by the prophet, “They that are in their sepulchres shall rise again,” and also, “There shall be a new heaven and a new earth: and the former shall not be mentioned, nor come into mind; but they shall find joy and rejoicing in it: for I will make Jerusalem a rejoicing, and my people a joy. And I will rejoice in Jerusalem, and joy in my people, and the voice of weeping shall be no more heard in her.” And by another prophet He uttered the same prediction: “At that time thy people shall be delivered, every one that shall be found written in the book. …

5. But you will say, the good will of a friend towards me, although I cannot see it, yet can I trace it out by many proofs; but you, what things you will us to believe not being seen, you have no proofs whereby to show them. In the mean time it is no slight thing, that you confess that by reason of the clearness of certain proofs, some things, even such as are not seen, ought to be believed: for even thus it is agreed, that not all things which are not seen, are not to be believed; and that saying, “that we ought not to believe things which we see not,” falls to the ground, cast away, and refuted. But they are much deceived, who think that we believe in Christ without any proofs concerning Christ. …

7. “Give heed unto me,” the Church says unto you; give heed unto me, whom ye see, although to see ye be unwilling. For the faithful, who were in those times in the land of Judæa, were present at, and learnt as present, Christ’s wonderful birth of a virgin, and His passion, resurrection, ascension; all His divine words and deeds. These things ye have not seen, and therefore ye refuse to believe. Therefore behold these things, fix your eyes on these things, these things which ye see reflect on, which are not told you as things past, nor foretold you as things future, but are shown you as things present. What? seemeth it to you a vain or a light thing. …

41. Besides this wonderful agreement between the types and the things typified, the adversary may be convinced by plain prophetic intimations, such as this: "In thy seed shall all nations be blessed." This was said to Abraham, and again to Isaac, and again to Jacob. Hence the significance of the words "I am the God of Abraham, and Isaac, and Jacob." God fulfills His promise to their seed in blessing all nations. With a like significance, Abraham himself, when he made his servant swear, told him to put his hand under his thigh; for he knew that thence would come the flesh of Christ, in whom we have now, not the promise of blessing to all nations, but the promise fulfilled.

Chapter 23. 25. In conclusion, the Testament is said to have been given to the flames by certain men in the time of persecution. Now let its lessons be read, from whatever source it has been brought to light. Certainly in the beginning of the promises of the Testator this is found to have been said to Abraham: "In thy seed shall all the nations of the earth be blessed;" and this saying is truthfully interpreted by the apostle: "To thy seed," he says, "which is Christ." No betrayal on the part of any man has made the promises of God of none effect. Hold communion with all the nations of the earth, and then you may boast that you have preserved the Testament from the destruction of the flames. …
