Isaias 2:4

4. If any one, however, advocating the cause of the Jews, do maintain that this new covenant consisted in the rearing of that temple which was built under Zerubbabel after the emigration to Babylon, and in the departure of the people from thence after the lapse of seventy years, let him know that the temple constructed of stones was indeed then rebuilt (for as yet that law was observed which had been made upon tables of stone), yet no new covenant was given, but they used the Mosaic law until the coming of the Lord; but from the Lord’s advent, the new covenant which brings back peace, and the law which gives life, has gone forth over the whole earth, as the prophets said: “For out of Zion shall go forth the law, and the word of the Lord from Jerusalem; and He shall rebuke many people; and they shall break down their swords into ploughshares, and their spears into pruning-hooks, and they …

But Abraham, (you say) was circumcised. Yes, but he pleased God before his circumcision; nor yet did he observe the Sabbath. For he had “accepted” circumcision; but such as was to be for “a sign” of that time, not for a prerogative title to salvation. In fact, subsequent patriarchs were uncircumcised, like Melchizedek, who, uncircumcised, offered to Abraham himself, already circumcised, on his return from battle, bread and wine. “But again,” (you say) “the son of Moses would upon one occasion have been choked by an angel, if Zipporah, had not circumcised the foreskin of the infant with a pebble; whence, “there is the greatest peril if any fail to circumcise the foreskin of his flesh.” Nay, but if circumcision altogether brought salvation, even Moses himself, in the case of his own son, would not have omitted to circumcise him on the eighth day; whereas it is agreed that Zipporah did it o …

So you cannot get out of this notion of yours a basis for your difference between the two Christs, as if the Jewish Christ were ordained by the Creator for the restoration of the people alone from its dispersion, whilst yours was appointed by the supremely good God for the liberation of the whole human race. Because, after all, the earliest Christians are found on the side of the Creator, not of Marcion, all nations being called to His kingdom, from the fact that God set up that kingdom from the tree (of the cross), when no Cerdon was yet born, much less a Marcion. However, when you are refuted on the call of the nations , you betake yourself to proselytes . …

Every opinion and the whole scheme of the impious and sacrilegious Marcion we now bring to the test of that very Gospel which, by his process of interpolation, he has made his own. To encourage a belief of this Gospel he has actually devised for it a sort of dower, in a work composed of contrary statements set in opposition, thence entitled Antitheses , and compiled with a view to such a severance of the law from the gospel as should divide the Deity into two, nay, diverse, gods, one for each Instrument, or Testament as it is more usual to call it; that by such means he might also patronize belief in “the Gospel according to the Antitheses.” These, however, I would have attacked in special combat, hand to hand; that is to say, I would have encountered singly the several devices of the Pontic heretic, if it were not much more convenient to refute them in and with that very gospel to which …

15. I find in your letter yet another objection in these words: “And add, that among all the many prophets who had been before, there is no one who has quoted from another word for word. For they had no need to go a-begging for words, since their own were true. But this one, in rebuking one of these men, quotes the words of the Lord, ‘The innocent and righteous shalt thou not slay.’” I cannot understand how, with all your exercise in investigating and meditating on the Scriptures, you have not noticed that the prophets continually quote each other almost word for word. For who of all believers does not know the words in Esaias? “And in the last days the mountain of the Lord shall be manifest, and the house of the Lord on the top of the mountains, and it shall be exalted above the hills; and all nations shall come unto it. …

All things, therefore, he says, when unbegotten, are in us potentially, not actually, as the grammatical or geometrical (art). If, then, one receives proper instruction and teaching, and (where consequently) what is bitter will be altered into what is sweet, that is, the spears into pruning-hooks, and the swords into plough-shares, there will not be chaff and wood begotten for fire, but mature fruit, fully formed, as I said, equal and similar to the unbegotten and indefinite power. If, however, a tree continues alone, not producing fruit fully formed, it is utterly destroyed. For somewhere near, he says, is the axe (which is laid) at the roots of the tree. Every tree, he says, which does not produce good fruit, is hewn down and cast into fire.

In Micah: “For the law shall go forth out of Sion, and the word of the Lord from Jerusalem. And He shall judge among many peoples, and He shall subdue and uncover strong nations.” Also in Isaiah: “For from Sion shall go forth the law, and the word of the Lord from Jerusalem; and He shall judge among the nations.” Likewise in the Gospel according to Matthew: “And behold a voice out of the cloud, saying, This is my beloved Son, in whom I am well pleased; hear ye Him.”

In Isaiah: “In the last times the mountain of the Lord shall be revealed, and the house of God upon the tops of the mountains; and it shall be exalted above the hills, and all nations shall come upon it, and many shall walk and say, Come, and let us go up into the mountain of the Lord, and into the house of the God of Jacob; and He will tell us His way, and we will walk in it. For from Sion shall proceed the law, and the word of the Lord from Jerusalem; and He shall judge among the nations, and shall rebuke much people; and they shall beat their swords into ploughshares, and their spears into pruning-hooks, and they shall no more learn to fight.” Also in the twenty-third Psalm: “Who shall ascend into the hill of the Lord, or who shall stand in His holy place? He that is innocent in his hands, and of a clean heart; who hath not received his life in vanity, and hath not sworn craftily to h …

And raising aloud the cry of victory over death, he said, “Where, O Death, is thy victory? Where, O Grave, is thy sting?” And another again, declaring glad tidings of the most profound peace, said, “They shall beat their swords into ploughshares, and their spears into pruning hooks.” And while one calls on Jerusalem, saying, “Rejoice greatly, O daughter of Sion, for lo! thy King cometh to thee meek, riding upon an ass, and a young colt;”another proclaims His second coming also, saying on this wise, “The Lord, whom ye seek, will come, and who will abide the day of His coming? Leap ye as calves set free from bonds.” And another again, amazed at such things, said, “This is our God; there shall none other be accounted of in comparison of Him.”

Who then is He that has done this, or who is He that has united in peace men that hated one another, save the beloved Son of the Father, the common Saviour of all, even Jesus Christ, Who by His own love underwent all things for our salvation? For even from of old it was prophesied of the peace He was to usher in, where the Scripture says: “They shall beat their swords into ploughshares, and their pikes into sickles, and nation shall not take the sword against nation, neither shall they learn war any more.” 2. And this is at least not incredible, inasmuch as even now those barbarians who have an innate savagery of manners, while they still sacrifice to the idols of their country, are mad against one another, and cannot endure to be a single hour without weapons: 3. …
