John Chrysostom

"And exalteth himself against all that is called God or is worshiped." For he will not introduce idolatry, but will be a kind of opponent to God; he will abolish all the gods, and will order men to worship him instead of God, and he will be seated in the temple of God, not that in Jerusalem only, but also in every Church. "Setting himself forth," he says; he does not say, saying it, but endeavoring to show it. For he will perform great works, and will show wonderful signs.
