Archbishop Fulton Sheen describes the final Antichrist thus:  Because his religion will be brotherhood of Man without the fatherhood of God, he will deceive even the elect. He will set up a counter church which will be the ape of the Church, because he, the Devil, is the ape of God.

It will be a mystical body of the Antichrist that will in all externals resemble the mystical body of Christ.—AB. Sheen’s talk in 1947, fully linked below:
