And we beseech you, brethren...
2That you be not easily moved from your sense, nor be terrified, neither by spirit, nor by word, nor by epistle...
3Let no man deceive you by any means, for unless there come a revolt first [apostacy from Christ/His Church], and the man of sin be revealed [Antichrist], the son of perdition,
4Who opposeth, and is lifted up above all that is called God, or that is worshipped, so that he sitteth in the temple of God [fake church], shewing himself as if he were God.
...
7For the mystery of iniquity [sinfulness.] already worketh; only that he who now holdeth, do hold [a true pope "holdeth back" evil], until he be taken out of the way [Pope Pius XII was taken out of the way; there hasn't been a valid pope since]...
8And then that wicked one shall be revealed whom the Lord Jesus shall kill with the Spirit of his mouth; and shall destroy with the brightness of his coming, him,
9Whose coming is according to the working of Satan, in all power, and signs, and
lying wonders,
10And in all
seduction of iniquity to them that perish; because they receive not the love of the truth, that they might be saved.
11Therefore God shall send them the operation of error,
to believe lying:
12That all may be judged who have not believed the truth, but have consented to iniquity.
-2 Thessalonians 2:1
