John Wesley on Revelation 12:7

And there was war in heaven - Here Satan makes his grand opposition to the kingdom of God; but an end is now put to his accusing the saints before God. The cause goes against him, verses 10, 11, Rev 12:10,11 and Michael executes the sentence. That Michael is a created angel, appears from his not daring, in disputing with Satan, Jude 9, to bring a railing accusation; but only saying, "The Lord rebuke thee." And this modesty is implied in his very name; for Michael signifies, "Who is like God?" which implies also his deep reverence toward God, and distance from all self - exaltation. Satan would be like God: the very name of Michael asks, "Who is like God?" Not Satan; not the highest archangel. It is he likewise that is afterward employed to seize, bind, and imprison that proud spirit.
