St Thomas Aquinas

The Antichrist shall fix his seat in the Temple which is in Jerusalem, which he shall have built up after it has lain in ruin. He shall sit in the temple of God as if he were God. He shall reign for three and a half years. He shall not be born of a virgin, but of a most wicked woman, and by the power of the devil he shall seem to work miracles, though they shall be only lying wonders.

Enoch and Elijah have been preserved from death and shall be sent to resist the Antichrist at the end of the world. They shall preach openly and oppose the Antichrist, and shall comfort and strengthen the faithful in the true faith. They shall continue to preach for three and a half years, and the Antichrist shall put them to death, but they shall rise again after three days.
