John Calvin's Commentary on the Bible

22 (Deuteronomy 18:22)

Verse 22

22.The prophet hath spoken it presumptuously. He not only condemns the folly and vanity of those who advance their own inventions in the place of God’s commands, but also their arrogance; since doubtless, this is impious and intolerable audacity, to set forth the offspring of man’s earthly brain as if it were a divine revelation. And on this ground it is that their impiety is detestable, who fill the air with the fumes of their revelations in order to alarm the simple. Wherefore, he adds, that they should “not be afraid” of such a prophet; because, as nothing can be more arrogant than the ministers of Satan, they confidently utter their boastings, by which we may be easily moved and even overwhelmed, unless we had this buckler to protect us, viz., that their terrific noise may be safely despised. This doctrine is now-a-days very useful for us. We know how insolently the Papists boast of the Catholic Church; of the Apostolic See; how fiercely they rage in Peter’s name; how impetuously they fulminate their curses and anathemas; but, when it is ascertained that whatever they put forward as revelations of the Spirit are but the empty figments of men, it will be easy to dispel those terrors which flow from this same fountain of presumption.
