Matthew 12:30

Wherein He shows how far He is from having borrowed any power from the Devil; teaching us how great the danger to think amiss of Him, not to be with Whom, is the same as to be against Him.

"He that is not with me is against me, and he that gathereth not with me scattereth abroad." Behold also a fourth refutation. For what is my desire? saith He. To bring men to God, to teach virtue, to proclaim the kingdom. What, that of the devil, and the evil spirits? The contrary to these. How then should he that gathers not with me, nor is at all with me, be likely to co-operate with me? And why do I say co-operate? Nay, on the contrary, his desire is rather to scatter abroad my goods. He then who is so far from cooperating that he even scatters abroad, how should he have exhited such unanimity with me, as with me to cast out the devils? Now it is a natural surmise that He said this not of the devil only, but Himself also of Himself, as being for His part against the devil, and scattering abroad his goods. And how, one may say, is he that is not with me against me? By this very fact, of his not gathering. But if this be true, much more he that is against him. For if he that doth not co-operate is an enemy, much more he that wages war. But all these things He saith, to indicate His enmity against the devil, how great and unspeakable it is. For tell me, if thou must go to war with any one, he that is not willing to fight on thy side, by this very fact is he not against thee? And if elsewhere He saith, "He that is not against you is for you," it is not contrary to this. For here He signified one actually against them, but there He points to one who in part is on their side: "For they cast out devils," it is said "in Thy name." But to me He seems here to be hinting also at the Jews, setting them on the devil's side. For they too were against Him, and were scattering what He gathered. As to the fact that He was hinting at them also, He declared it by speaking thus, "Therefore I say unto you, that all manner of sin and blasphemy shall be forgiven unto men."

But let none think that this is said of heretics and schismatics; though we may apply it besides to such; but it is shown by the context to refer to the Devil; in that the works of the Saviour cannot be compared with the works of Beelzebub. He seeks to hold men's souls in captivity, the Lord to set them free; he preaches idols, the Lord the knowledge of the true God; he draws men to sin, the Lord calls them back to virtues. How then can these have agreement together, whose works are so opposite?

Therefore He has spoiled his house, in that them whom He foresaw should be His own, He set free from the snares of the Devil, and has joined to the Church. Or in that He has divided the whole world among His Apostles and their successors to be converted. By this plain parable therefore He shows that He does not join in a deceitful working with the dæmons as they falsely accused Him, but by the might of His divinity He frees men from the dæmons.
