John Calvin on John 7:13

13. Yet no man spoke openly of him for fear of the Jews. By the Jews he here means the rulers, who had the government in their hands. They burned with such hatred against Christ, that they did not permit a word to be uttered on either side. Not that they were displeased at any reproaches which were heaped upon him, but because they could discover no better expedient than that his name should be buried in oblivion. Thus the enemies of the truth, after having found that they gain nothing by their cruelty, desire nothing more than to suppress the remembrance of him, and this object alone they strive to attain. That all were silent, being subdued by fear, was a proof of gross tyranny, as I have already said; for as unbridled licentiousness has no place in a well-regulated Church, so when all freedom is held oppressed by fear, it is a most wretched condition. But the power of our Lord Jesus Christ shone forth with greater and more wonderful brightness, when — causing himself to be heard amidst armed foes, and amidst their furious resentment, and under so formidable a government — he openly maintained and asserted the truth of God.

John 7:14-19

14. And about the middle of the feast, Jesus went up into the temple, and taught. 15. And the Jews wondered, saying, How doth this man know letters, since he did not learn them? 16. Jesus answered them, and said, My doctrine is not mine, but that of him who sent me. 17. If any man wish to do his will, he shall know of the doctrine, if it be of God, or if I speak from myself. 18. He who speaketh from himself seeketh his own glory; but he who seeketh the glory of him who sent him is true, and there is no unrighteousness in him. 19. Did not Moses give you the law, and not one of you keepeth the law? Why do you seek to kill me?
