Having now briefly arranged these points in order as we best could, it follows that, agreeably to our intention from the first, we refute those who think that the Father of our Lord Jesus Christ is a different God from Him who gave the answers of the law to Moses, or commissioned the prophets, who is the God of our fathers, Abraham, Isaac, and Jacob. For in this article of faith, first of all, we must be firmly grounded. We have to consider, then, the expression of frequent recurrence in the Gospels, and subjoined to all the acts of our Lord and Saviour, "that it might be fulfilled which was spoken by this or that prophet," it being manifest that the prophets are the prophets of that God who made the world. From this therefore we draw the conclusion, that He who sent the prophets, Himself predicted what was to be foretold of Christ. And there is no doubt that the Father Himself, and not another different from Him, uttered these predictions. The practice, moreover, of the Saviour or His apostles, frequently quoting illustrations from the Old Testament, shows that they attribute authority to the ancients. The injunction also of the Saviour, when exhorting His disciples to the exercise of kindness, "Be ye perfect, even as your Father who is in heaven is perfect; for He commands His sun to rise upon the evil and the good, and sendeth rain on the just and on the unjust," ¹ most evidently suggests even to a person of feeble understanding, that He is proposing to the imitation of His disciples no other God than the maker of heaven and the bestower of the rain. Again, what else does the expression, which ought to be used by those who pray, "Our Father who art in heaven," ² appear to indicate, save that God is to be sought in the better parts of the world, i.e., of His creation? Further, do not those admirable principles which He lays down respecting oaths, saying that we ought not to "swear either by heaven, because it is the throne of God; nor by the earth, because it is His footstool," ³ harmonize most clearly with the words of the prophet, "Heaven is My throne, and the earth is My footstool?" ⁴ And also when casting out of the temple those who sold sheep, and oxen, and doves, and pouring out the tables of the money-changers, and saying, "Take these things, hence, and do not make My Father's house a house of merchandise," ⁵ He undoubtedly called Him His Father, to whose name Solomon had raised a magnificent temple. The words, moreover, "Have you not read what was spoken by God to Moses: I am the God of Abraham, and the God of Isaac, and the God of Jacob; He is not a God of the dead, but of the living," ⁶ most clearly teach us, that He called the God of the patriarchs (because they were holy, and were alive) the God of the living, the same, viz., who had said in the prophets, "I am God, and besides Me there is no God." ⁷ For if the Saviour, knowing that He who is written in the law is the God of Abraham, and that it is the same who says, "I am God, and besides Me there is no God, acknowledges that very one to be His Father who is ignorant of the existence of any other God above Himself, as the heretics suppose, He absurdly declares Him to be His Father who does not know of a greater God. But if it is not from ignorance, but from deceit, that He says there is no other God than Himself, then it is a much greater absurdity to confess that His Father is guilty of falsehood. From all which this conclusion is arrived at, that He knows of no other Father than God, the Founder and Creator of all things.
