Thematic Bible: Speaking evil of, forbidden

Yet in the very same way these men, too, cherishing vain dreams, pollute our human nature, reject control, and malign the Mighty. Yet even Michael, the Archangel, when, in his dispute with the Devil, he was arguing about the body of Moses, did not venture to charge him with maligning, but said merely 'The Lord rebuke you!' But these men malign whatever they do not understand; while they use such things as they know by instinct (like the animals that have no reason) for their own corruption.
