Augustine of Hippo, on John 13:31

“When he therefore was gone out, Jesus said: Now is the Son of man glorified, and God is glorified in him.”

“(Tr. lxiii. 2) Or thus: The unclean went out: the clean remained with their cleanser. Thus will it be when the tares are separated from the wheat; The righteous shall shine forth as the sun in the kingdom of their Father. (Matt. 13:43) Our Lord, foreseeing this, said, when Judas went out, as if the tares were now separated, and He left alone with the wheat, the holy Apostles, Now is the Son of man glorified; as if to say, Behold what will take place at My glorifying, at winch none of the wicked shall be present, none of the righteous shall perish. He does not say, Now is the glorifying of the Son of man signified; but, Now is the Son of man glorified; as it is not that rock signified Christ, but, That Rock was Christ. (1 Cor. 10:4) Scripture often speaks of the things signifying, as if they were the things signified. (c. 3). But the glorifying of the Son of man, is the glorifying of God in Him; as He adds, And God is glorified in Him, which He proceeds to explain; If God is glorified in Him—for He came not to do His own will, but the will of Him that sent Him—God shall also glorify Him in Himself, so that the human nature which was assumed by the eternal Word, shall also be endowed with eternity. And shall straightway glorify Him. He predicts His own resurrection, which was to follow immediately, not at the end of the world, like ours. Thus it is; Now is the Son of man glorified; the now referring not to His approaching Passion, but the resurrection which was immediately to follow it: as if that which was so very soon to be, had already taken place.”
