He that is not with me is against me; and he that gathers not with me scatters abroad.
All Commentaries on Matthew 12:30 Go To Matthew 12
John Chrysostom
AD 407
After that third reply, here follows a fourth, “He that is not with me is against me.”.
Therefore whoso gathereth not with me, nor is with me, may not be compared together with me, that with me he should cast out daemons, but rather seeks to scatter what is mine. But tell me; If you were to have fought together with some one, and he should not be willing to come to your aid, is he not therefore against you? The Lord also Himself said in another place, “He that is not against you is for you.” To which that which is here said is not contrary. For here He is speaking of the Devil who is our adversary—there of some man who was on their side, of whom it is, said, “We saw one casting out daemons in thy name.”
