Book Four, Part One
that thou also, as thou hast requested, mayest obtain from me the means of confuting all the heretics everywhere, and not permit them, beaten back at all points, to launch out further into the deep of error, nor to be drowned in the sea of ignorance; but that thou, turning them into the haven of the truth, mayest cause them to attain their salvation.
The man, however, who would undertake their conversion, must possess an accurate knowledge of their systems or schemes of doctrine. For it is impossible for any one to heal the sick, if he has no knowledge of the disease of the patients.
I have proved, in a variety of ways, that the Son of God accomplished the whole dispensation [of mercy], and have shown that there is none other called God by the Scriptures except the Father of all, and the Son, and those who possess the adoption.
Since, therefore, this is sure and stedfast, that no other God or Lord was announced by the Spirit, except Him who, as God, rules over all, together with His Word, and those who receive the Spirit of adoption, that is, those who believe in the one and true God, and in Jesus Christ the Son of God; and likewise that the apostles did Of themselves term no one else as God, or name [no other] as Lord; and, what is much more important, [since it is true] that our Lord [acted likewise], who did also command us to confess no one as Father, except Him who is in the heavens, who is the one God and the one Father;-those things are clearly shown to be false which these deceivers and most perverse sophists advance....these perverse mythologists state, setting their thoughts against God; and, putting aside the doctrine of Christ, and of themselves divining falsehoods, they dispute against the entire dispensation of God.
And if He did indeed teach us to call one Being Father and God, while He does from time to time Himself confess other fathers and gods in the same sense, then He will appear to enjoin a different course upon His disciples from what He follows Himself. Such conduct, however, does not bespeak the good teacher, but a misleading and invidious one. The apostles, too, according to these men's showing, are proved to be transgressors of the commandment, since they confess the Creator as God, and Lord, and Father
But since the writings (literae) of Moses are the words of Christ, He does Himself declare to the Jews, as John has recorded in the Gospel: "If ye had believed Moses, ye would have believed Me: for he wrote of Me. But if ye believe not his writings, neither will ye believe My words." He thus indicates in the clearest manner that the writings of Moses are His words. If, then, [this be the case with regard] to Moses, so also, beyond a doubt, the words of the other prophets are His [words], as I have pointed out. And again, the Lord Himself exhibits Abraham as having said to the rich man, with reference to all those who were still alive: "If they do not obey Moses and the prophets, neither, if any one were to rise from the dead and go to them, will they believe him." .... the Lord reveals [to us] their end; showing at the same time, that if they obeyed Moses and the prophets, they would believe in Him whom these had preached, the Son of God, who rose from the dead, and bestows life upon us; and He shows that all are from one essence, that is, Abraham, and Moses, and the prophets, and also the Lord Himself, who rose from the dead
Known Before1. Therefore Abraham also, knowing the. Father through the Word, who made heaven and earth, confessed Him to be God; and having learned, by an announcement [made to him], that the Son of God would be a man among men, by whose advent his seed should be as the stars of heaven, he desired to see that day, so that he might himself also embrace Christ; and, seeing it through the spirit of prophecy, he rejoiced. Wherefore Simeon also, one of his descendants, carried fully out the rejoicing of the patriarch, and said: "Lord, now lettest Thou Thy servant depart in peace. For mine eyes have seen Thy salvation, which Thou hast prepared before the face of all people: a light for the revelation of the Gentiles, and the glory of the people Israel." And the angels, in like manner, announced tidings of great joy to the shepherds who were keeping watch by night. Moreover, Mary said, "My soul doth magnify the Lord, and my spirit hath rejoiced in God my salvation; " -the rejoicing of Abraham descending upon those who sprang from him,-those, namely, who were watching, and who beheld Christ, and believed in Him; while, on the other hand, there was a reciprocal rejoicing which passed backwards from the children to Abraham, who did also desire to see the day of Christ's coming. Rightly, then, did our Lord bear witness to him, saying, "Your father Abraham rejoiced to see my day; and he saw it, and was glad."
2. For not alone upon Abraham's account did He say these things, but also that He might point out how all who have known God from the beginning, and have foretold the advent of Christ, have received the revelation from the Son Himself; who also in the last times was made visible and passable, and spake with the human race, that He might from the stones raise up children unto Abraham, and fulfil the promise which God had given him, and that He might make his seed as the stars of heaven, as John the Baptist says: "For God is able from these stones to raise up children unto Abraham." Now, this Jesus did by drawing us off from the religion of stones, and bringing us over from hard and fruitless cogitations, and establishing in us a faith like to Abraham. As Paul does also testify, saying that we are children of Abraham because of the similarity of our faith, and the promise of inheritance.
For David had been appointed a priest by God, although Saul persecuted him. For all the righteous possess the sacerdotal rank. And all the apostles of the Lord are priests, who do inherit here neither lands nor houses, but serve God and the altar continually
Wherefore also John does appropriately relate that the Lord said to the Jews: "Ye search the Scriptures, in which ye think ye have eternal life; these are they which testify of me. And ye are not willing to come unto Me, that ye may have life." How therefore did the Scriptures testify of Him, unless they were from one and the same Father, instructing men beforehand as to the advent of His Son, and foretelling the salvation brought in by Him? "For if ye had believed Moses, ye would also have believed Me; for he wrote of Me; " [saying this, ] no doubt, because the Son of God is implanted everywhere throughout his writings:
