1 You remember, my beloved, that in the last discourse, by occasion of the passage of the Gospel read, we spoke to you concerning the Holy Spirit. When the Lord had invited those that believe in Him to this drinking, speaking among those who meditated to lay hold of Him, and sought to kill Him, and were not able, because it was not His will: well, when He had spoken these things, there arose a dissension among the multitude concerning Him; some thinking that He was the very Christ, others saying that Christ shall not arise from Galilee.
But they who had been sent to take Him returned clear of the crime and full of admiration. For they even gave witness to His divine doctrine, when those by whom they had been sent asked, “Why have ye not brought him?” They answered that they had never heard a man so speak: “For not any man so speaks.” But He spoke thus, because He was God and man. But the Pharisees, repelling their testimony, said to them: “Are ye also deceived?” We see, indeed, that you also have been charmed by his discourses.
“Hath any one of the rulers or the Pharisees believed on him? But this multitude who know not the law are cursed.” They who knew not the law believed on Him who had sent the law; and those men who were teaching the law despised Him, that it might be fulfilled which the Lord Himself had said, “I have come that they who see not may see, and they that see may be made blind.” For the Pharisees, the teachers of the law, were made blind, and the people that knew not the law, and yet believed on the author of the law, were enlightened.
