1 The passage of the holy Gospel of which we have before discoursed to you, beloved, is followed by that of today, which has just now been read. Both the disciples and the Jews heard the Lord speaking; both men of truth and liars heard the Truth speaking; both friends and enemies heard Charity speaking; both good men and bad men heard the Good speaking. They heard, but He discerned; He saw and foresaw whom His discourse profited and would profit. Among those who were then, He saw; among us who were to be, He foresaw. Let us therefore hear the Gospel, just as if we were listening to the Lord Himself present: nor let us say, O happy they who were able to see Him! Because there were many of them who saw, and also killed Him; and there are many among us who have not seen Him, and yet have believed. For the precious truth that sounded forth from the mouth of the Lord was both written for our sakes, and preserved for our sakes, and recited for our sakes, and will be recited also for the sake of our prosperity, even until the end of the world. The Lord is above; but the Lord, the Truth, is also here. For the body of the Lord, in which He rose again from the dead, can be only in one place; but His truth is everywhere diffused. Let us then hear the Lord, and let us also speak that which He shall have granted to us concerning His own words.
2. “Did not Moses,” says He, “give you the law, and yet none of you does the law? Why do ye seek to kill me?” For you seek to kill me just for this reason, that none of you does the law; for if you did do the law, you would recognize Christ in its very letters, and you would not kill Him when present with you. And they answered: “The crowd answered Him;” answered as a tumultuous crowd, things not pertaining to order, but to confusion; in a word, the crowd was disturbed. See what answer it made: “You have a devil: who seeks to kill you?” As if it were not worse to say, “You have a devil,” than to kill Him. To Him, indeed, was it said, that He had a devil, who was casting out devils. What else can a turbulent disorderly crowd say? What else can filth stirred up do but stink? The crowd was disturbed; by what? By the truth. For the eyes that have not soundness cannot endure the brightness of the light.
