The people answered him, We have heard out of the law that Christ abides forever: and how say you,
The Son of man must be lifted up?
who is this Son of man?
All Commentaries on John 12:34 Go To John 12
Cyril of Alexandria
AD 444
And this they say, as we have remarked, understanding that being "lifted up" meant being crucified. For it was their wont to signify by more auspicious names things which pointed directly to sore disasters. They essay therefore by means of the Scripture to prove that Christ speaks falsehood. For the Scripture, says [one of them], denies that the Christ is but for a time, when it says concerning Him: Thou art a Priest for ever. How then sayest Thou: "I am the Christ," whereas Thou sayest that Thou wilt die? For, because they understand not, the Jews say that by reason of the Passion He cannot be Christ; and they deny that it was written that the Christ must suffer and rise again and ascend unto the Father, to be Minister of the Sanctuary and High Priest of our souls, when He should return to life, a Conqueror and Incorruptible. Albeit the Scripture foretells expressly, not only that He should come in this common fashion of a Man, but that He should die for the life of all men, and should return to life again after breaking asunder the bonds of death: whereby the saying that Christ abideth for ever is fully and fitly accomplished. For when He had shown Himself superior to death and corruption, He ascended unto the Father.
