1. Now I shall simply say, in opposition to all the heretics, and principally against the followers of Marcion, and against those who are like to these, in maintaining that the prophets were from another God [than He who is announced in the Gospel], read with earnest care that Gospel which has been conveyed to us by the apostles, and read with earnest care the prophets, and you will find that the whole conduct, and all the doctrine, and all the sufferings of our Lord, were predicted through them. But if a thought of this kind should then suggest itself to you, to say, What then did the Lord bring to us by His advent?— know that He brought all [possible] novelty, by bringing Himself who had been announced. For this very thing was proclaimed beforehand, that a novelty should come to renew and quicken mankind. For the advent of the King is previously announced by those servants who are sent [before Him], in order to the preparation and equipment of those men who are to entertain their Lord. But when the King has actually come, and those who are His subjects have been filled with that joy which was proclaimed beforehand, and have attained to that liberty which He bestows, and share in the sight of Him, and have listened to His words, and have enjoyed the gifts which He confers, the question will not then be asked by any that are possessed of sense what new thing the King has brought beyond [that proclaimed by] those who announced His coming. For He has brought Himself, and has bestowed on men those good things which were announced beforehand, which things the angels desired to look into. 1 Peter 1:12
2. But the servants would then have been proved false, and not sent by the Lord, if Christ on His advent, by being found exactly such as He was previously announced, had not fulfilled their words. Wherefore He said,
Think not that I have come to destroy the law or the prophets; I came not to destroy, but to fulfil. For verily I say unto you, Until heaven and earth pass away, one jot or one tittle shall not pass from the law and the prophets till all come to pass. Romans 3:21 For by His advent He Himself fulfilled all things, and does still fulfil in the Church the new covenant foretold by the law, onwards to the consummation [of all things]. To this effect also Paul, His apostle, says in the Epistle to the Romans,
But now, Matthew 5:17-18 without the law, has the righteousness of God been manifested, being witnessed by the law and the prophets; for the just shall live by faith. Romans 1:17 But this fact, that the just shall live by faith, had been previously announced Habakkuk 2:4 by the prophets.
3. But whence could the prophets have had power to predict the advent of the King, and to preach beforehand that liberty which was bestowed by Him, and previously to announce all things which were done by Christ, His words, His works, and His sufferings, and to predict the new covenant, if they had received prophetical inspiration from another God [than He who is revealed in the Gospel], they being ignorant, as you allege, of the ineffable Father, of His kingdom, and His dispensations, which the Son of God fulfilled when He came upon earth in these last times? Neither are you in a position to say that these things came to pass by a certain kind of chance, as if they were spoken by the prophets in regard to some other person, while like events happened to the Lord. For all the prophets prophesied these same things, but they never came to pass in the case of any one of the ancients. For if these things had happened to any man among them of old time, those [prophets] who lived subsequently would certainly not have prophesied that these events should come to pass in the last times. Moreover, there is in fact none among the fathers, nor the prophets, nor the ancient kings, in whose case any one of these things properly and specifically took place. For all indeed prophesied as to the sufferings of Christ, but they themselves were far from enduring sufferings similar to what was predicted. And the points connected with the passion of the Lord, which were foretold, were realized in no other case. For neither did it happen at the death of any man among the ancients that the sun set at mid-day, nor was the veil of the temple rent, nor did the earth quake, nor were the rocks rent, nor did the dead rise up, nor was any one of these men [of old] raised up on the third day, nor received into heaven, nor at his assumption were the heavens opened, nor did the nations believe in the name of any other; nor did any from among them, having been dead and rising again, lay open the new covenant of liberty. Therefore the prophets spoke not of any one else but of the Lord, in whom all these aforesaid tokens concurred.
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 shall no longer learn to fight. Isaiah 2:3-4; Micah 4:2-3 If therefore another law and word, going forth from Jerusalem, brought in such a [reign of] peace among the Gentiles which received it (the word), and convinced, through them, many a nation of its folly, then [only] it appears that the prophets spoke of some other person. But if the law of liberty, that is, the word of God, preached by the apostles (who went forth from Jerusalem) throughout all the earth, caused such a change in the state of things, that these [nations] did form the swords and war-lances into ploughshares, and changed them into pruning-hooks for reaping the grain, [that is], into instruments used for peaceful purposes, and that they are now unaccustomed to fighting, but when smitten, offer also the other cheek, Matthew 5:39 then the prophets have not spoken these things of any other person, but of Him who effected them. This person is our Lord, and in Him is that declaration borne out; since it is He Himself who has made the plough, and introduced the pruning-hook, that is, the first semination of man, which was the creation exhibited in Adam, and the gathering in of the produce in the last times by the Word; and, for this reason, since He joined the beginning to the end, and is the Lord of both, He has finally displayed the plough, in that the wood has been joined on to the iron, and has thus cleansed His land; because the Word, having been firmly united to flesh, and in its mechanism fixed with pins, has reclaimed the savage earth. In the beginning, He figured forth the pruning-hook by means of Abel, pointing out that there should be a gathering in of a righteous race of men. He says,
For behold how the just man perishes, and no man considers it; and righteous men are taken away, and no man lays it to heart. Isaiah 57:1 These things were acted beforehand in Abel, were also previously declared by the prophets, but were accomplished in the Lord's person; and the same [is still true] with regard to us, the body following the example of the Head.
5. Such are the arguments proper [to be used] in opposition to those who maintain that the prophets [were inspired] by a different God, and that our Lord [came] from another Father, if perchance [these heretics] may at length desist from such extreme folly. This is my earnest object in adducing these Scriptural proofs, that confuting them, as far as in me lies, by these very passages, I may restrain them from such great blasphemy, and from insanely fabricating a multitude of gods.
