John Calvin on Mark 1:26

Mark 1:26 When the unclean spirit had torn him Luke uses a milder phrase, when the devil had thrown him down: but they agree perfectly as to the meaning; for the design of both was to show, that the devil went out of the man in a violent manner. He threw down the unhappy man, as if he had intended to tear him: but Luke says that the attempt was unsuccessful; for he hurt him nothing Not that the attack was, in no degree whatever, attended by injury, or at least by some feeling of pain; but that the man was afterwards delivered from the devil, and restored to perfect health.
