XX.  In my opinion He is called Son because He is identical with the Father in Essence; and not only for this reason, but also because He is Of Him.  And He is called Only-Begotten, not because He is the only Son and of the Father alone, and only a Son; but also because the manner of His Sonship is peculiar to Himself and not shared by bodies.  And He is called the Word, because He is related to the Father as Word to Mind; not only on account of His passionless Generation, but also because of the Union, and of His declaratory function.  Perhaps too this relation might be compared to that between the Definition and the Thing defined Of the oration on Christmas Day, where He is called ὁ τοῦ Πατρὸς ὅρος καὶ λόγος, and see Note there. since this also is called Λόγος. Ratio (relation; sometimes reason) Sermo (discourse) and Verbum (Word) are all renderings of Λόγος.  For, it says, he that hath mental perception of the Son (for this is the meaning of Hath Seen) hath also perceived the Father; John xiv. 9. and the Son is a concise demonstration and easy setting forth of the Father’s Nature.  For every thing that is begotten is a silent word of him that begat it.  And if any one should say that this Name was given Him because He exists in all things that are, he would not be wrong.  For what is there that consists but by the word?  He is also called Wisdom, as the Knowledge of things divine and human.  For how is it possible that He Who made all things should be ignorant of the reasons of what He has made?  And Power, as the Sustainer of all created things, and the Furnisher to them of power to keep themselves together.  And Truth, as being in nature One and not many (for truth is one and falsehood is manifold), and as the pure Seal of the Father and His most unerring Impress.  And the Image as of one substance with Him, and because He is of the Father, and not the Father of Him.  For this is of the Nature of an Image, to be the reproduction of its Archetype, and of that whose name it bears; only that there is more here.  For in ordinary language an image is a motionless representation of that which has motion; but in this case it is the living reproduction of the Living One, and is more exactly like than was Seth to Adam, Gen. v. 3. or any son to his father.  For such is the nature of simple Existences, that it is not correct to say of them that they are Like in one particular and Unlike in another; but they are a complete resemblance, and should rather be called Identical than Like.  Moreover he is called Light as being the Brightness of souls cleansed by word and life.  For if ignorance and sin be darkness, knowledge and a godly life will be Light.…And He is called Life, because He is Light, and is the constituting and creating Power of every reasonable soul.  For in Him we live and move and have our being, Acts xvii. 28. according to the double power of that Breathing into us; for we were all inspired by Him with breath, Gen. ii. 7. and as many of us as were capable of it, and in so far as we open the mouth of our mind, with God the Holy Ghost.  He is Righteousness, because He distributes according to that which we deserve, and is a righteous Arbiter both for those who are under the Law and for those who are under Grace, for soul and body, so that the former should rule, and the latter obey, and the higher have supremacy over the lower; that the worse may not rise in rebellion against the better.  He is Sanctification, as being Purity, that the Pure may be contained by Purity.  And Redemption, because He sets us free, who were held captive under sin, giving Himself a Ransom for us, the Sacrifice to make expiation for the world.  And Resurrection, because He raises up from hence, and brings to life again us, who were slain by sin.
