Mark 1:27 Commentary - Whedon's Commentary on the Old and New Testaments

27. What new doctrine A new set of facts was coming to light; a new power was being disclosed. Men’s ideas must open to the new views and new doctrines as soon as a being has appeared on earth superior to and in antagonism with the powers of darkness. Indeed, it is important to remark that, striking as was the testimony rendered to the heavenly mission of Jesus, from the fact that his miracles were in opposition to the ills of men, to their diseases, their sorrows, and deaths, including the whole ruin that sin produces, there was needed this miracle of casting out devils from their dominion over men, to place the opposition between him and the powers of hell in the clearest view. He is the friend of man; an opponent of sin, death, and hell. Hence it seems, in fact, that it was this very miracle of casting out devils that his enemies subsequently felt themselves most called upon to explain by perverting.
