This apostasy among the churches signals the closeness of the end. And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. The Zoroastrians of Iran believe the frog was a special agent of Ahriman, or Satan. Zoroaster taught 300 years before Alexander the Great, and is said to have founded the wisdom of the magi. Imperial Rome, and the incarnate Pope, and the false prophet which is the Pope prior to Satan's casting-out from heaven.
Spirits follow words, and the doctrine of Rome is deceit and anathema to the Word.
In Revelation 17, the woman controlling the beast from the earth, the USA, was the Roman Catholic church. I searched the word 'abomination' in the Bible. Aside from foods proscribed by the Law it includes homosexuality, sex with women in menstruation, adultery, buggery, incest, homosexuality, the wages of sexual immorality, fornication, cross-dressing, idolatry, false teaching, atheism, rejecting the faith and murder. The widely-ranging activity of these spirits, indicates the spread of falsehood and mutiny against God among world leaders, as they are drawn into the culminating assault of creaturely defiance. This new trinity manifested between the Sixth and Seventh Vials, just before the Seals opened to finish the mystery of God.
