Augustine of Hippo
Catena Aurea · Johannesevangelium 12
Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour. Father, glorify thy name. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again. The people therefore, that stood by, and heard it, said that it thundered: others said, An angel spake to him. Jesus answered and said, This voice came not because of me, but for your sakes. Now is the judgment of this world: now shall the prince of this world be cast out. And I, if I be lifted up from the earth, will draw all men unto me. This he said, signifying what death he should die. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again. The people therefore that stood by and heard it, said that it thundered. Jesus answered and said, This voice came not because of Me, but for your sakes.
(Tr. lii. 11) If I be lifted up from the earth, He says, i. e. when I shall be lifted up. He does not doubt that the work will be accomplished which He came to do. By His being lifted up, He means His passion on the cross, as the Evangelist adds: This He said, signifying by what death He should die.
