Then said Jesus unto them,
When you have lifted up the Son of man, then shall you know that I am he, and that I do nothing of myself; but as my Father has taught me, I speak these things.

Cyril of Alexandria
AD 444
Christ spent long time dwelling with the Jews, and speaking in every synagogue, so to say, and addressing them every sabbath-day and, setting before them often and ungrudgingly profitable teaching, was continually inviting them to the illumination through the Spirit, and verily He saith, in that He is God by Nature and Very, I am the light of the world; but they thinking most foolishly were ever gainsaying Him who said these things, for (says he) THOU bearest record of Thyself, Thy record is not true. And not at contradictions in words did the daring of the Jews stay, nor only in love of reviling was their untamed audacity consummated, but going without stint through all savageness, they at last betrayed Him both to Cross and Death. But since He was by Nature Life, having burst the bonds of death, He arose from the dead and (as was reasonable) departs from Jewish defilement and hasted away from Israel and that with justice, and betaking Himself to the Gentiles, He invited all to the Light, and to the blind He freely bestowed recovery of sight. It befell then that after the Death on the Cross of our Saviour Christ, the understandings of the Jews were darkened, in that the Light had departed forth from them, and that the hearts of the Gentiles were enlightened, in that the Very Light beamed upon them. When then, He says, ye have lifted up the Son of Man, then shall ye know that I am, instead of, I will await the consummation of your impiety, I will not bring upon you wrath before its time, I will accept the Passion and Death, I will endure along with the rest this too. But when ye shall betray to the Cross the Son of Man deemed by you to be bare man, then shall ye know, even against your will, that not falsely have I said that I am the Light of the world. For when ye see yourselves darkened, the innumerable multitude of the Gentiles enlightened by having Me with them, how will ye not even against your will agree that I am of a truth the light of the world? For that the Saviour was going to depart from the Synagogue of the Jews after His coming to Life again from the dead, is doubtful to none (for it has been accomplished and done): yet may one see it somehow (yea even clearly) from His words, While ye have the Light walk in the Light, lest darkness come upon you. For the repression and withdrawal of light generates darkness, and again the presence of light causes darkness to vanish. Therefore is Christ shewn as being of a truth Light, Who darkened the Jews through His Departure from them, and enlightened the Gentiles through His Presence with them: and a bitter lesson to the Jews was their experience of dread things.
