Revelation 13
Here the scene shifts to describe two great beasts. The first, a beast with seven heads and ten horns (the antichrist), who is closely identified with the dragon in Rev.12:3 (Satan). Then a second beast is described as coming up out of the earth having two horns like a lamb (the false prophet) completing the evil trinity. Together they will institute a series of deceptions, which will bring the whole world under the control of the beast with seven heads and ten horns, and ultimately Satan.
Surely it needs no argument to prove that these three evil persons are opposed to and are the antithesis of the three Persons in the Godhead. The Devil stands opposed to God the Father - ‘Ye are of your father, the Devil,” (John 8:40) The Antichrist stands opposed to God the Son - his very name shows this. The third person of the Trinity of Evil will be an Anti-spirit, who will simulate and oppose the Spirit of God. Just as the great work of the Holy Spirit is to glorify Christ, so the one aim of the Anti-spirit will be to magnify the false christ (Rev.13:12).
These three are the counterfeit trinity and like all fakes, they can be spotted. You just need to know what to look for.
The Truth
“Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world.” (1 John 4:1-3)
