Moreover, as the authority of the other evangelists bears witness, He certainly spoke more openly with those who were His disciples than with those who were not. He did this when He was alone with them, apart from the multitude of others.
For then He explained to them the parables which He told to others while leaving them obscure. What, then, does "I have said nothing in secret" mean?
Yet His words, "I have spoken openly to the world," should be understood as though He said, "Many have heard Me." The very word "openly" was in one sense open, and in another sense not open.
It was open, because many heard. Yet it was not open, because many did not understand.
And what He said separately to His disciples, however one may take it, He did not say in secret. For who speaks in secret when he speaks before so many people?
For it is written, "At the word of two witnesses, or at the word of three witnesses, a matter shall be established" (Deut 19:15).
This is all the more true if He spoke to a few what He wished to reveal to many through them. Concerning this the Lord Himself says to the few who were with Him: "What I tell you in the dark, speak in the light; and what you hear in the ear, preach upon the housetops" (Mt 10:27).
Therefore, the very thing which seemed to be spoken by Him in a hidden manner was, in a certain sense, not spoken as a secret. For He did not speak so that those to whom it was said should keep silence.
Rather, He spoke so that it might be preached everywhere. Thus something may be said openly and yet not openly, or secretly and yet not as a secret.
For it is said, "that seeing they may see and not see" (cf. Mk 4:12). Why do they "see," if not because it is open and not secret?
And why do the same persons "not see," if not because it is not open, but hidden?
Yet the very thing which men heard and did not understand was such that it could not truly become a charge of crime against Him.
And whenever they questioned Him in order to find something by which to accuse Him, He answered them in such a way that all their snares were broken and their devices confounded.
For this reason He said, "Why do you ask Me? Ask those who heard what I said to them; behold, they know what I said."
