Charles Ellicott Commentary Luke 22:70

"And they all said, Art thou then the Son of God? And he said unto them, Ye say that I am." — Luke 22:70 (ASV)

You say that I am.—The question, as asked by the whole company of priests and elders, is given only by Saint Luke. It apparently followed, as a spontaneous cry of indignant horror, on the answer which had been made to the adjuration of the high priest. The answer is complete in itself; but it implies, as in the less ambiguous forms in Saint Matthew and Saint Mark, the confession that He actually was what they had asked Him. The “I am” has something of the same significance as in John 7:24-25; John 8:58 (where see Notes).
