John Chrysostom
Catena Aurea · Johannesevangelium 18
The high priest then asked Jesus of his disciples, and of his doctrine. Jesus answered him, I spake openly to the world; I ever taught in the synagogue, and in the temple, whither the Jews always resort; and in secret have I said nothing. Why askest thou me? ask them which heard me, what I have said unto them: behold, they know what I said.
(Hom. lxxxiii) Or, He spoke in secret, but not, as these thought, from fear, or to excite sedition; but only when what He said was above the understanding of the many. To establish the matter, however, upon superabundant evidence, He adds, Why askest thou Me? ask them which heard Me what I said unto them; behold, they know what I said unto them: as if He said, Thou askest Me of My disciples; ask My enemies, who lie in wait for Me. These are the words of one who was confident of the truth of what He said: for it is incontrovertible evidence, when enemies are called in as witnesses.
