Q. In revelation 16 John sees three unclean spirits come out of the false prophet, the beast and the dragon. Could the dragon be an extraterrestrial/ angel or even a physical embodiment of Satan himself? In the passage he clearly is represented as a third person in the unholy trinity. Keep up the good work.

A. The dragon in Rev. 16 is the same as the one introduced in Rev. 12. and mentioned several times there and afterward. In Rev. 12:9 he’s identified as Satan, who leads the whole world astray.
