THE HOLY SEAT OF THE ANTI- CHRIST:
Then spake Jesus to the multitude, and to his disciples, Saying, The scribes and the Pharisees sit in Moses' seat:(Matthew 23:1-2).
The Anti-Christ sitteth in the Temple of God:
Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 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, shewing himself that he is God.(2Thes.2:3-4)
