John 7:15

And the Jews wondered, saying, &c. "They marvelled," says Cyril, "when they saw in Him such unheard-of wisdom and power of speech;" for, as Theophylact says, "He spake wondrous words, restraining and changing their minds in a wondrous manner," so that their fury was changed into love and admiration of Christ. "For they heard Him," says S. Augustine, "disputing about the law, and adducing its testimony," and explaining it with such grace and manner as was not human but divine. For, as he adds, "Many knew where He was born, and how brought up, but had never seen Him learning anything." And hence the Scribes ought to have inferred that His great learning and wisdom had not been acquired by study, but infused by God. But blinded and stupefied by hatred they stand still in wonder, and proceed not to investigate the origin of that which surprises them. So S. Chrysostom. And for this very cause God willed that Jesus should leap up into the chair of learning, not from the schools, but from the carpenter's trade, to the end that all might acknowledge that His learning, was not taught by man but inspired by God.

Ver. 16. Jesus answered, &c. My doctrines are not My inventions nor the result of My study. They did not primarily and originally proceed from Me, but from God the Father. He, as I am God, communicated to Me His own omniscience, But, as I am man, He gave and infused into Me His own Blessed knowledge of all things, according to that of Isaiah 11:2. "The Spirit of the Lord shall rest upon Him," &c. So S. Chrysostom and others, who observe that in this very way Christ implies that He is God: as if He said, "I together with the Divine Essence have derived all My omniscience and doctrine from the Father." As S. Augustine says (Tract 29), "What is the doctrine of the Father, but the Word of the Father? Christ Himself, therefore, is the doctrine of the Father, if He is the Word of the Father. But because a Word cannot be of no one, but of some one, He called Himself His own doctrine, and yet not His own, because He is the Word of the Father. For what is so much thine as thyself? and what is so little thine as thyself if thou art from some one else?" Ver 17. If any one is willing, &c. That is, something invented by Me, and therefore disagreeing, or contrary to the will of God. As S. Chrysostom says, "If anybody has love of virtue, he will understand the force of My words that they come from God. For of Him cometh every virtue, of which I am the earnest teacher. For he who loves to observe the commands of God in this matter, will love and observe My Word, because I do not say or do anything contrary to what is pleasing and commanded by God;" tacitly hinting that they loved vice, and therefore were opposed to the teaching both of God and Himself. "Put away," says Chrysostom, "this doubt, your anger and malice and intense hatred of Me, and nothing will then keep you from acknowledging that My words are those of God. But now these tempers obscure your judgment, and if you put them aside you would think otherwise."
