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.
2. “Nicodemus,” however, “one of the Pharisees, who had come to the Lord by night,”— not indeed as being himself unbelieving, but timid; for therefore he came by night to the light, because he wished to be enlightened and feared to be known—Nicodemus, I say, answered the Jews, “Does our law judge a man before it hear him, and know what he does?” For they perversely wished to condemn before they examined. Nicodemus indeed knew, or rather believed, that if only they were willing to give Him a patient hearing, they would perhaps become like those who were sent to take Him, but preferred to believe. They answered, from the prejudice of their heart, what they had answered to those officers, “Are you also a Galilean?” That is, one seduced as it were by the Galilean. For the Lord was said to be a Galilean, because His parents were from the city of Nazareth. I have said “His parents” in regard to Mary, not as regards the seed of man; for on earth He sought but a mother, He had already a Father on high. For His nativity on both sides was marvellous: divine without mother, human without father. What, then, said those would-be doctors of the law to Nicodemus? “Search the Scriptures, and see that out of Galilee arises no prophet.” Yet the Lord of the prophets arose thence. “They returned,” says the evangelist, “every man to his own house.”
3. “Thence Jesus went unto the mount;” namely, to mount “Olivet,”— unto the fruitful mount, unto the mount of ointment, unto the mount of chrism. For where, indeed, but on mount Olivet did it become the Christ to teach? For the name of Christ is from chrism; χρισμα in the Greek, is called in Latin unctio, an anointing. And He has anointed us for this reason, because He has made us wrestlers against the devil. “And early in the morning He came again into the temple, and all the people came unto Him; and He sat down and taught them.” And He was not taken, for He did not yet deign to suffer.
