Luther said in about 1520 that the Pope is the antichrist precisely BECAUSE he is found in the middle of Christ's church, pretending to rule over it. He didn't come up with the idea. Hus said it before him, and some monks said it before either of them.
The fools on here saying that the church itself is bad or unnecessary are also antichrists, just like Mohammed or Karl Marx were antichrists. They just aren't THE antichrist; because the antichrist sits in the temple of God, claiming to be God.
It's not just because this pope is a communist and says there is no hell that he's the antichrist. All popes are the antichrist. Their seat is the seat of antichrist, because the papal throne claims to be over the church and identical with Christ's throne, even when the papacy denies the gospel of Christ.
If the pope is involved in a conspiracy to establish a world government, it should come as no surprise. The papacy has been doing this since the middle ages at least.
"For Paul, 2 Thess. 2:3, in describing to the Thessalonians Antichrist, calls him 'an adversary of Christ, who opposeth and exalteth himself above all that is called God, or that is worshipped, 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….The Pope exercises a twofold tyranny: he defends his errors by force and by murders, and forbids judicial examination [of his teaching[. The latter does even more injury than any executions, because, when the true judgment of the Church is removed, godless dogmas and godless services cannot be removed, and for many ages they destroy innumerable souls."
