Matthew 12:26

applies the axiom to Satan, εἰ, introduces a simple particular supposition without reference to its truth. ἐμερείσθη : the aorist has the force of a perfect. Satan casting out Satan means self-stultification; ipso facto, self-division results. Against the argument it might be objected: Kingdoms and cities do become divided against themselves, regardless of fatal consequences, why not also Satan? Why should not that happen to Satan's kingdom which has happened even to the Christian Church? Jesus seems to have credited Satan with more astuteness than is possessed by states, cities, and churches. Satan may be wicked, He says in effect, but he is not a fool. Then it has to be considered that communities commit follies which individuals avoid. Men war against each other to their common undoing, who would be wiser in their own affairs. One Satan might cast out another, but no Satan will cast out himself. And that is the case put by Jesus. Some, e.g., De Wette and Fritzsche, take ὁ Σατανᾶς τ. Σ. ἐκβάλλει as = one Satan casting out another. But that is not Christ's meaning. He so puts the case as to make the absurdity evident. Ex hypothesi He had a right to put it so; for the theory was that Satan directly empowered and enabled Him to deliver men from his (Satan's) power.

Matthew 12:27. To the previous convincing argument Jesus adds an argumentum ad hominem, based on the exorcism then practised among the Jews, with which it would appear the Pharisees found no fault. οἱ υἱοὶ ὑμῶν, not of course Christ's disciples (so most of the Fathers), for the Pharisaic prejudice against Him would extend to them, but men belonging to the same school or religious type, like-minded. By referring to their performances Jesus put the Pharisees in a dilemma. Either they must condemn both forms of dispossession or explain why they made a difference. What they would have said we do not know, but it is not difficult to suggest reasons. The Jewish exorcists operated in conventional fashion by use of herbs and magical formulæ, and the results were probably insignificant. The practice was sanctioned by custom, and harmless. But in casting out devils, as in all other things, Jesus was original, and His method was too effectual. His power, manifest to all, was His offence. κριταί. Jesus now makes the fellow-religionists of the Pharisees their judges. On a future occasion He will make John the Baptist their judge (Matthew 21:23-27). Such home-thrusts were very inconvenient.
