"The term comes from 1 John 4:1-3:
(NIV) Dear
friends, do not believe every spirit, but test the spirits to see whether they
are from
GodÉThis is the spirit of the antichrist, which you have heard is
coming and even now is already in the world.
"The person is described here and
also in 2 Thessalonians 2, Daniel 7, and Revelation 13.
