John Calvin on Acts 4:17-18

17. In threatening let us threaten. Here may we see what a deadly evil power void of the fear of God is. For when that religion and reverence which ought doth not reign, the more holy the place is which a man doth possess, the more boldly “Audacius,” audaciously. doth he rage. For which cause we [should] always take good heed that the wicked be not preferred unto the government of the Church. And those which are called to this function must behave themselves reverently and modestly, lest they seem to be armed to do hurt. But and if it so happen they abuse their honor, the Spirit declareth there, as in a glass, what small account we ought to make of their decrees and commandments. “Quam pro nihilo ducendum sit quicquid decernunt et jubent,” that whatever they order and decree ought to be held as null. The authority of the pastors hath certain bounds appointed which they may not pass. And if they dare be so bold, we may lawfully refuse to obey them; for if we should, it were in us great wickedness, as it followeth now.

Acts 4:19-23

19. And Peter and John answered them, and said, Whether it be right in the sight of God to hearken unto you rather than to God, judge ye. 20. For we cannot but speak those things which we have seen and heard. 21. And when they had threatened them, they let them go, finding nothing. for which they might punish them, because of the people; for all men did glorify God because of that which was done. 22. For the man was more than forty years old on whom the sign of healing was showed. 23. Furthermore, when they were let go, they came to their fellows, and told them whatsoever things the priests and elders had said.
