John 18:19

He does not ask in order to know the truth, but to find out some charge against Him, on which to deliver Him to the Roman Governor to be condemned. But our Lord so tempers His answer, as neither to conceal the truth, nor yet to appear to defend Himself: 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.

"The high priest then asked Jesus of His disciples, and of His doctrine." O the wickedness! Though he had continually heard Him speaking in the temple and teaching openly, he now desires to be informed. For since they had no charge to bring, they enquired concerning His disciples, perhaps where they were, and why He had collected them, and with what intention, and on what terms. And this he said, as desiring to prove Him to be a seditious person and an innovator, since no one gave heed to Him, except them alone, as though His were some factory of wickedness.

The high priest therefore asked Jesus of His disciples, and of His teaching. A teacher of the people, learned in the Law, one of those on whom the Divine bidding lays the duty, "Judge ye righteous judgment," after having taken the Lord, as though He had been a notorious robber, by a band of armed soldiers and a number of impious officers, asks Him of His disciples and of His doctrine, showing thereby that he was in want of charges to bring against Him. For the Man Who was now on trial knew no sin. He asks Him about His doctrine, to elicit from Him whether it accorded with the Mosaic Law, or coincided and concurred with the old dispensation; and what purpose His disciples had implanted in their hearts, whether to submit to be guided by ancient customs, or to practise any strange and novel kind of worship. He did this in malice, for he supposed that Christ would make an outspoken attack on the Law, and that, by pleading for the rejection of the Mosaic dispensation, He would excite the Jews to embittered and furious revilings against Himself, so that He might in the future appear to be paying a just penalty for deliberately fighting against God. For to enter the lists against the Divine commandments, if any mere human being were convicted of any word or deed with that intent, were to declare oneself an open enemy of God. And they were treating Christ as a mere man, and thought that they were doing well to chastise the Lord of the Law for the transgression of the Law, not remembering him that said: Impious is he that saith unto a king, Thou art a law-breaker.
