The Antichrist
The claim that the pope is the Antichrist has been part of anti-Catholic rhetoric since the Reformation, when it was needed to justify the Protestant Reformers’ desire to leave the Catholic Church.
Thus the Lutheran Book of Concord states, “[T]he pope is the real Antichrist who has raised himself over and set himself against Christ . . . Accordingly, just as we cannot adore the devil himself as our lord or God, so we cannot suffer his apostle, the pope or Antichrist, to govern us as our head or lord” (Smalcald Articles 2:4:10, 14).
The Presbyterian and Anglican Westminster Confession states, “There is no other head of the church but the Lord Jesus Christ; nor can the pope of Rome in any sense be the head thereof; but is that Antichrist, that man of sin, and that son of perdition, that exalteth himself in the church against Christ, and all that is called God” (25:6).
To make the prophecies of the Antichrist fit the pope, some even claimed that “the temple of God” in which the Antichrist pretends to be God (2 Thess. 2:4) is the Vatican.
Although the Fathers of the Church speculated on the Antichrist in various ways, they would never have agreed. They showed the temple to be the Jewish temple, rebuilt by Antichrist in Jerusalem. Rather than the bishop of Rome, the early Fathers identified the Antichrist as a government official—a king coming to power in the ruins of the Roman Empire. He would probably be Jewish, possibly from the tribe of Dan. And most importantly, rather than claiming like the pope to be the vicar or emissary of Jesus Christ, he would claim that Jesus was not the Christ but that he was instead. He would then seduce many of the Jewish people by attempting to fulfill the political aspirations they held for the Messiah. The quotes that follow illustrate both the different ideas they had about the Antichrist and how different their conception was from the anti-papal idea that arose in later centuries.
“[T]he whole time of your faith will not profit you unless you are made complete in the last time. For in the last days false prophets and corrupters shall be multiplied, and sheep shall be turned into wolves . . . and then shall the deceiver of the world appear, pretending to be the Son of God, and [he] shall do signs and wonders, and the earth shall be delivered into his hands” (Didache 16:3-4 [A.D. 70]).
The AntiChrist from the CA library should help, since it shows what the ECF wrote about this.
