If I have told you earthly things, and you believe not, how shall you believe, if I tell you of heavenly things?
All Commentaries on John 3:12 Go To John 3
Cyril of Alexandria
A doctrine, saith He, not exceeding the understanding befitting man, ye from your extreme folly received not, and how shall I explain to you things more Divine? For they who in their own matters are most foolish, how shall they be wise in matters above them? And they who are powerless as to the less, how shall they not find the greater intolerable? And if, says He, ye believe not Me being Alone in speaking, but seek many witnesses for every thing, whom shall I bring to you as a witness of the heavenly Mysteries? For no man hath ascended up to heaven but He That came down from heaven the Son of man. For since the Word of God came down from heaven, He says that the son of man came down, refusing after the Incarnation to be divided into two persons, and not suffering certain to say that the Temple taken by reason of need of the Virgin is one Son, the Word again which appeared from God the Father another: save only as regards the distinction which belongs to each by nature. For as He is the Word of God, so Man too of a woman, but One Christ of both, Undivided in regard of Sonship and God-befitting Glory. For how does He clothe as its own the Temple of the Virgin, with what befitteth the bare Word Alone: and again appropriateth to Himself what befitteth the Flesh only? For now He saith that the Son of man hath come down from heaven: but at the time of His Passion, He feareth, and is sore afraid, and very heavy, and is recorded as Himself suffering the Sufferings which befitted His Human Nature only.
