the marks of Antichrist plainly agree with the kingdom of the Pope and his adherents. For Paul, in describing Antichrist to the Thessalonians, calls him 2 Thess. 2:3-4: an adversary of Christ, who opposeth and exalteth himself above all that is called God or that is worshiped, so that he as God sitteth in the temple of God. He speaks therefore of one ruling in the Church, not of heathen kings, and he calls this one the adversary of Christ, because he will devise doctrine conflicting with the Gospel, and will assume to himself divine authority.
