24. Since the Word is from God, He must be Son. Since the Son is from everlasting, He must be the Word; else either He is superior to the Word, or the Word is the Father. Texts of the New Testamentwhich state the unity of the Son with the Father; therefore the Son is the Word. Three hypotheses refuted— 1. That the Man is the Son; 2. That the Word and Man together are the Son; 3. That the Word became Son on His incarnation. Texts of the Old Testamentwhich speak of the Son. If they are merely prophetical, then those concerning the Word may be such also
18 Perhaps they will have so little shame as to say, that this utterance belongs not to the Son but to the Word; but from what preceded it appeared plainly that the speaker was the Son. For He who here says, 'I came not to judge the world but to save,' is shown to be no other than the Only-begotten Son of God, by the same John's saying before, 'For God so loved the world that He gave His Only-begotten Son, that whosoever believes in Him should not perish, but have everlasting life. For God sent not His Son into the world to condemn the world, but that the world through Him might be saved. He that believes in Him is not condemned, but he that believes not is condemned already, because he has not believed in the Name of the Only-begotten Son of God. And this is the condemnation, that light has come into the world, and men loved darkness rather than light, because their deeds are evil. ' If He who says, 'For I came not to judge the world, but that I might save it,' is the Same as says, 'He that sees Me, sees Him that sent Me,' and if He who came to save the world and not judge it is the Only-begotten Son of God, it is plain that it is the same Son who says, 'He that sees Me, sees Him that sent Me.' For He who said, 'He that believes in Me,' and, 'If any one hear My words, I judge him not,' is the Son Himself, of whom Scripture says, 'He that believes in Him is not condemned, but He that believes not is condemned already, because He has not believed in the Name of the Only-begotten Son of God.' And again: 'And this is the condemnation' of him who believes not on the Son, 'that light has come into the world,' and they believed not in Him, that is, in the Son; for He must be 'the Light which lights every man that comes into the world. ' And as long as He was upon earth according to the Incarnation, He was Light in the world, as He said Himself, 'While you have light, believe in the light, that you may be the children of light;' for 'I,' says He, 'have come a light into the world. '
19. This then being shown, it follows that the Word is the Son. But if the Son is the Light, which has come into the world, beyond all dispute the world was made by the Son. For in the beginning of the Gospel, the Evangelist, speaking of John the Baptist, says, 'He was not that Light, but that he might bear witness concerning that Light. ' For Christ Himself was, as we have said before, the True Light that lights every man that comes into the world. For if 'He was in the world, and the world was made by Him,' of necessity He is the Word of God, concerning whom also the Evangelist witnesses that all things were made by Him. For either they will be compelled to speak of two worlds, that the one may have come into being by the Son and the other by the Word, or, if the world is one and the creation one, it follows that Son and Word are one and the same before all creation, for by Him it came into being. Therefore if as by the Word, so by the Son also all things came to be, it will not be contradictory, but even identical to say, for instance, 'In the beginning was the Word,' or, 'In the beginning was the Son.' But if because John did not say, 'In the beginning was the Son,' they shall maintain that the attributes of the Word do not suit with the Son, it at once follows that the attributes of the Son do not suit with the Word. But it was shown that to the Son belongs, 'I and the Father are One,' and that it is He 'Who is in the bosom of the Father,' and, 'He that sees Me, sees Him that sent Me;' and that 'the world was brought into being by Him,' is common to the Word and the Son; so that from this the Son is shown to be before the world; for of necessity the Framer is before the things brought into being. And what is said to Philip must belong, according to them, not to the Word, but to the Son. For, 'Jesus said,' says Scripture, 'Have I been so long time with you, and yet you have not known Me, Philip? He that has seen Me, has seen the Father. And how do you say then, Show us the Father? Do you not believe, that I am in the Father and the Father in Me? The words that I speak unto you, I speak not of Myself, but the Father that dwells in Me, He does the works. Believe Me that I am in the Father and the Father in Me, or else, believe Me for the very works' sake. Verily, verily, I say unto you, he that believes in Me, the works that I do shall he do also, and greater works than these shall he do, because I go unto the Father. And whatsoever you shall ask in My Name, that will I do, that the Father may be glorified in the Son. ' Therefore if the Father be glorified in the Son, the Son must be He who said, 'I in the Father and the Father in Me;' and He who said, 'He that has seen Me, has seen the Father.' for He, the same who thus spoke, shows Himself to be the Son, by adding, 'that the Father may be glorified in the Son.'
20. If then they say that the Man whom the Word wore, and not the Word, is the Son of God the Only-begotten, the Man must be by consequence He who is in the Father, in whom also the Father is; and the Man must be He who is One with the Father, and who is in the bosom of the Father, and the True Light. And they will be compelled to say that through the Man Himself the world came into being, and that the Man was He who came not to judge the world but to save it; and that He it was who was in being before Abraham came to be. For, says Scripture, Jesus said to them, 'Verily, verily, I say unto you, before Abraham was, I am.' And is it not absurd to say, as they do, that one who came of the seed of Abraham after two and forty generations, should exist before Abraham came to be? Is it not absurd, if the flesh, which the Word bore, itself is the Son, to say that the flesh from Mary is that by which the world was made? And how will they retain 'He was in the world?' for the Evangelist, by way of signifying the Son's antecedence to the birth according to the flesh, goes on to say, 'He was in the world.' And how, if not the Word but the Man is the Son, can He save the world, being Himself one of the world? And if this does not shame them, where shall be the Word, the Man being in the Father? And where will the Word stand to the Father, the Man and the Father being One? But if the Man be Only-begotten, what will be the place of the Word? Either one must say that He comes second, or, if He be above the Only-begotten, He must be the Father Himself. For as the Father is One, so also the Only-begotten from Him is One; and what has the Word above the Man, if the Word is not the Son? For, while Scripture says that through the Son and the Word the world was brought to be, and it is common to the Word and to the Son to frame the world, yet Scripture proceeds to place the sight of the Father, not in the Word but in the Son, and to attribute the saving of the world, not to the Word, but to the Only-begotten Son. For, says it, Jesus said, 'Have I been so long while with you, and yet have you not known Me, Philip? He that has seen Me, has seen the Father.' Nor does Scripture say that the Word knows the Father, but the Son; and that not the Word sees the Father, but the Only-begotten Son who is in the bosom of the Father.
