Catena Aurea · Johannesevangelium 12
Jesus cried and said, He that believeth on me, believeth not on me, but on him that sent me. And he that seeth me seeth him that sent me. I am come a light into the world, that whosoever believeth on me should not abide in darkness. And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world. He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day. For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak. And I know that His commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
(Tr. liv. 7) When the Father gave the Son a commandment, He did not give Him what He had not: for in the Wisdom of the Father, i. e. in the Word, are all the commandments of the Father. The commandment is said to be given, because it is not from him to whom it is said to be given. But to give the Son that which He never was without, is the same as to beget the Son who never was not.
