3. He is therefore one and the same God, who called Abraham and gave him the promise. But He is the Creator, who does also through Christ prepare lights in the world, [namely] those who believe from among the Gentiles. And He says, "Ye are the light of the world;" that is, as the stars of heaven. Him, therefore, I have rightly shown to be known by no man, unless by the Son, and to whomsoever the Son shall reveal Him. But the Son reveals the Father to all to whom He wills that He should be known; and neither without the goodwill of the Father, nor without the agency of the Son, can any man know God. Wherefore did the Lord say to His disciples, "I am the way, the truth, and the life: and no man cometh unto the Father but by me. If ye had known me, ye would have known my Father also: and from henceforth ye have both known Him, and have seen Him." From these words it is evident, that He is known by the Son, that is, by the Word.
