Catena Aurea · Johannesevangelium 7
After these things Jesus walked in Galilee: for he would not walk in Jewry, because the Jews sought to kill him. Now the Jews’ feast of tabernacles was at hand. His brethren therefore said unto him, Depart hence, and go into Judæa, that thy disciples also may see the works that thou doest. For there is no man that doeth any thing in secret, and he himself seeketh to be known openly. If thou do these things, shew thyself to the world. For neither did his brethren believe in him. Then Jesus said unto them, My time is not yet come: but your time is alway ready. The world cannot hate you: but me it hateth, because I testify of it, that the works thereof are evil. Go ye up unto this feast: I go not up yet unto this feast; for my time is not yet fully come.
(Tr. xxviii. 3) When you hear of our Lord’s brethren, you must understand the kindred of Mary, not her offspring after our Lord’s birth. For as the body of our Lord once only lay in the sepulchre, and neither before, nor after that once; so could not the womb of Mary have possibly conceived any other mortal offspring. Our Lord’s works did not escape His disciples, but they escaped His brethren; hence their suggestion, That Thy disciples may see the works that Thou doest. They speak according to the wisdom of the flesh, to the Word that was made flesh, and add, For there is no man that doeth any thing in secret, and he himself seeketh to be known openly. If Thou do these things, shew Thyself to the world; as if to say, Thou doest miracles, do them in the eyes of the world, that the world may honour Thee. Their admonitions aim at procuring glory for Him; and this very thing, viz. aiming at human glory, proved that they did not believe in Him, as we next read, For neither did His brethren believe on Him. They were Christ’s kindred, but they were on that very account above believing in Him.
