John 18:21

"Why askest thou Me? Ask them which heard Me." These are not the words of one speaking arrogantly, but of one confiding in the truth of what He had said. What therefore He said at the beginning, "If I bear witness of Myself, My witness is not true," this He now implieth, desiring to render His testimony abundantly credible. For when Annas mentioned the disciples, what saith He? "Dost thou ask Me concerning Mine? Ask Mine enemies, ask those who have plotted against Me, who have bound Me; let them speak." This is an unquestionable proof of truth, when one calls his enemies to be witnesses to what he saith.

(Tr. cxiii. 3) For what they had heard and not understood, was not of such a kind, as that they could justly turn it against Him. And as often as they tried by questioning to find out some charge against Him, He so replied as to blunt all their stratagems, and refute their calumnies.

"The high priest then asked Jesus of His disciples, and of His doctrine. Jesus answered him, I spake openly to the world; I always taught in the synagogue, and in the temple, whither all the Jews resort, and in secret have I said nothing. Why askest thou me? ask those who heard me, what I have said unto them: behold, they know what I said." A question occurs that ought not to be passed over, how it is that the Lord Jesus said, "I spake openly to the world;" and in particular that which He afterwards added, "In secret have I said nothing." Did He not, even in that latest discourse which He delivered to the disciples after supper, say to them, "These things have I spoken unto you in proverbs; but the hour cometh, when I shall no more speak unto you in proverbs, but I shall show you plainly of my Father"? If, then, He spake not openly even to the more intimate company of His disciples, but gave the promise of a time when He would speak openly, how was it that He spake openly to the world? And still further, as is also testified on the authority of the other evangelists, to those who were truly His own, in comparison with others who were not His disciples, He certainly spake with much greater plainness when He was alone with them at a distance from the multitudes; for then He unfolded to them the parables, which He had uttered in obscure terms to others. What then is the meaning of the words, "In secret have I said nothing"? It is in this way we are to understand His saying, "I spake openly to the world;" as if He had said, There were many that heard me. And that word "openly" was in a certain sense openly and in another sense not openly. It was openly, because many heard Him; and again it was not openly, because they did not understand Him. And even what He spake to His disciples apart, He certainly spake not in secret. For who speaketh in secret, that speaketh before so many persons; as it is written, "At the mouth of two or three witnesses shall every word be established:" especially if that be spoken to a few which he wisheth to become known to many through them; as the Lord Himself said to the few whom He had as yet, "What I tell you in darkness, that speak ye in light; and what ye hear in the ear, that preach ye upon the house-tops"? And accordingly the very thing that seemed to be spoken by Himself in secret, was in a certain sense not spoken in secret; for it was not so spoken to remain unuttered by those to whom it was spoken; but rather so in order to be preached in every possible direction. A thing therefore may be uttered at once openly, and not openly; or at the same time in secret, and yet not in secret, as it is said, "That seeing, they may see, and not see." For how "may they see," save only because it is openly, and not in secret; and again, how is it that the same parties "may not see," save that it is not openly, but in secret? Howbeit the very things which they had heard without understanding, were such as could not with justice or truth be turned into a criminal charge against Him: and as often as they tried by their questions to find something whereof to accuse Him, He gave them such replies as utterly discomfited all their plots, and left no ground for the calumnies they devised. Therefore He said, "Why askest thou me? ask those who heard me, what I have said unto them: behold, they know what I said."
