From the early Church Fathers to now.
“The multitude answered him: We have heard out of the law, that Christ abideth for ever; and how sayest thou: The Son of man must be lifted up? Who is this Son of man?”
“(Hom. lxviii. 1) Hence we see, that they understood many of the things that He spake in parables. As He had talked about death a little time before, they saw now what was meant by His being lifted up.”
“(Hom. lxviii. 1) And see how maliciously they put the question. They do not say, We have heard out of the law, that Christ doth not suffer; for in many places of Scripture His passion and resurrection are spoken of together, but, abideth for ever. And yet His immortality was not inconsistent with the fact of His suffering. They thought this proved however that He was not Christ. Then they ask, Who is this Son of man? another malicious question; as if to say, Do not charge us with putting this question out of hatred to Thee; for we simply ask for information. Christ shews them in His answer that His passion does not prevent Him from abiding for ever: Then Jesus said unto them, Yet a little while is the light with you: as if His death were but going away for a time, as the sun’s light only sets to rise again.”
“(Hom. lxviii. 1) He does not mean only the time before His crucifixion, but the whole of their lives. For many believed on Him after His crucifixion. Lest darkness come upon you.”
“(Hom. lxviii. 1) What things do the Jews now, and know not what they do; thinking, like men in the dark, that they are going the right road, while they are taking directly the wrong one. Wherefore He adds, While ye have the light, believe in the light.”
“(Hom. lxviii) i. e. My children. In the beginning of the Gospel it is said, Born of God, (c. 1:13) i. e. of the Father. But here He Himself is the Begetter. The same act is the act both of Father and Son.”
“(Hom. lxviii. 1) But why did He hide Himself, when they neither took up stones to cast at Him, nor blasphemed? Because He saw into their hearts, and knew the fury they were in; and therefore did not wait till they broke out into act, but retired to give their envy time to subside.”
“(Tr. lii. 12) The Jews when they understood that our Lord spoke of His own death, asked how that could be: The people answered Him, We have heard out of the law that Christ abideth for ever: and how sayest Thou, The Son of man must be lifted up? Who is this Son of man? Though our Lord did not call Himself the Son of man here, they remembered that He often called Himself so; as He had just before: The hour is come, that the Son of man should be glorified. They remember this, and ask, If Christ abideth for ever, how will He be lifted up from the earth; i. e. how will He die upon the cross?”
“(Tr. lii. 12) Or they interpreted the word by their own intended act. It was not wisdom imparted, but conscience disturbed, which disclosed its meaning to them.”
“(Tr. lii. 13) Yet a little while is the light with you. Hence it is that ye understand1 that Christ abideth for ever. Wherefore walk while ye have the light, approach, understand the whole, that Christ will both die, and live for ever: do this while ye have the light.”
“(Tr. lii. 13) i. e. if ye so believe in the eternity of Christ, as to deny His humiliation and death.”
“(Tr. lii) i. e. While ye have any truth, believe in the truth, that ye may be born again of the truth: That ye may be the children of the light.”
“(Tr. lii) Not from those which began to believe in and love Him, but from those who saw and envied Him. When He hid Himself, He consulted our weakness, He did not derogate from His own power.”
