And Jesus answered them, saying,
The hour is come, that the Son of man should be glorified.

Cyril of Alexandria
AD 444
Seeing therefore that Gentiles are hastening in eager desire to see Him and to turn towards Him, on this account He says: The hour is come. For near at hand was the time of His Passion, after which the calling of the Gentiles immediately followed. And He calls the time now present "the hour," with the intention of shewing that no other occasion can bring Him to the necessity of suffering, save only this season marked out by His own appointed limitations. For having done all things that were to lead men on to faith, and having preached the word of the kingdom of heaven, He now desires to pass onward to the very crowning point of His hope, namely to the destruction of death: and this could not otherwise be brought to pass, unless the Life underwent death for the sake of all men, that so in Him we all may live. For on this account also He speaks of Himself as glorified in His Death, and in suffering terrible things at the hands of the sinners who dishonour Him. Even though by the angels in heaven He had been glorified from everlasting, yet nevertheless His Cross was the beginning of His being glorified upon earth by the Gentiles as God. For after He had left to themselves the Jews who openly despised Him, He turned to the Gentiles and is glorified by them as God, being confidently expected to come again in the glory of the Father. And He declares not merely that the Word shall then be glorified, but, shewing that He Who is ineffably to be regarded as sharing in humanity no less than Deity is One Only Son, He uses the title "Son of man:" for He is One Son and One Christ, capable since His Incarnation of no separation of Nature; but ever remaining and ever regarded as God, although clothed in flesh.
(From the Syriac.) [He is One Son and One Christ, capable since His Incarnation of no separation of Nature,] except so far as this, that we may say that we acknowledge separately the Nature of the Word and [the nature] of the flesh. And [we may say] that they are not the same in conception, for the one is of the Essence of God the Father, but the other had its root upon earth in the holy Virgin. Nevertheless there is only One Christ of the two, Who is not divided into a duality of Sons after the concourse of these Natures which have been mentioned, but remains and is regarded as in possession of the power of the Godhead, although clothed in Flesh.
