But if I cast out demons by the Spirit of God, then the kingdom of God is come unto you.

John Chrysostom
AD 407
To cast out demons is a work of the highest power and not of any ordinary power. For Matthew said, “If it is by the Spirit of God that I cast out demons,” just as Luke said, “If I by the finger of God cast out the demons.” The inference then might seem to be that if this is so, then quite obviously the Son of God has appeared. This, however, he did not quite say directly but in a reserved way so as not to provoke them. He dimly intimates it by saying “then the kingdom of God has come upon you.” Do you grasp this wisdom? His presence was quietly shining forth precisely through the very things to which they were assigning blame. Then, to conciliate them, Jesus said not simply “the kingdom is come” but in a personal sense “to you.” It is as though he had said, “Good things have come specifically to you, so why then do you feel so displeased that you are being wonderfully blessed? Why do you make war against your own salvation? This is that very time which the prophets long ago foretold. This is the sign of that advent which was expected by them. Even these things now are being accomplished by divine power. You yourselves know that they are happening. That is a fact. But that they are being accomplished by divine power, you do not realize, so the deeds themselves cry out. It is impossible that Satan should be the stronger power now, for he must of necessity be weaker. For it cannot be that one who is weak can, as though strong, cast out the strong man, the devil.” In speaking thus Jesus at the same time pointed to the power of charity and the vulnerability of contentious divisiveness.
