Then said they unto him, Who are you? And Jesus said unto them,
Even the same that I said unto you from the beginning.

Cyril of Alexandria
AD 444
They said therefore to Him, Who art THOU?
Their word commingled with fiercest anger proceeds from boastfulness. For they eagerly ask, not to learn and believe, but out of much madness they spring (so to speak) on Christ. For He says in more simple word, I am, not adding, God of God, nor yet ought else to indicate His inherent Glory; but in lowly wise and apart from all boasting He says only this I am, leaving it to the better instructed to add what was wanting; and they go on to wildest and unbridled madness, and from unmeasured haughtiness they all but cut short the Saviour's word not yet advanced to its completion, and so to say rebuke and interrupt Him in the middle and say, Who art THOU? This is the part of one who openly says, Dost Thou dare to think of Thyself ought greater than WE know? we know that Thou art son of the carpenter, a man low and most poor, of no note with us and altogether nought. They therefore condemn the Lord as being nought, looking only to His family after the flesh, but the Magnificence that pertains to His works, and still more His Generation from above and from the Father, whence they might specially recognize that He is by Nature God, they do not so much as admit into their mind. For who will work the things that befit God Alone? will not He surely Who is by Nature God? but Christ wrought them; He therefore was and is God, even when made Flesh for the salvation and life of all. But they whose belief is confined to their own mis-counsels, and take no account at all of our Divine and Divinely-inspired Scripture; they in regard of the very things for which they ought to give thanks, do disparage Him, knowing neither what they say, nor whereof they affirm.
Punctuating therefore with emphasis at the word THOU, and throwing back what is called the acute accent, we take the word as a question with note of admiration; for they say THOU, as though, Thou Who art nothing at all, and art known by us to be so, Thou Who art mean and of mean extraction, what canst Thou say illustrious of Thyself, what worth speaking of those about Thee? For nought of such daring is foreign to Jewish madness.
