I'm just curious 'where' you found those quotes from the Scriptures?
It's within my past studies of the four Empires starting with the Babylonian Empire up to the revived Roman Empire including a deep study of the Jesuit Militant Priesthood. The Jesuits have always secretly controlled the government of every nation from the time of Ignatius Loyola and his military background as the Pope gave approval for the Society of Jesus in 1540.
Rev 13 the beast rises up out of the sea as the sea here is symbolic of people and nations as in a sea of humanity, Daniel Chapter 7:1-8; Revelation 17:15. This beast is a Luciferian system that controls world wide economics, political, military, educational, environmental and false religious system. This beast system that Satan works through gives its power to the beast out of the earth as the beast out of the earth appears as the Lamb of God, but is a false Christ being the son of perdition, 2 Thessalonians 2:3-12, with two horns. The two horns represent the Old Roman Empire that received its deadly wound back in 1798 by General Berthier who made his entrance into Rome and abolished the Roman government and established a secular one. That caused them to scatter into the other ten nations (ten horns). The wound was healed in 1929 by Mussolini. The deadly wound came in 1798 when General Berthier of France, who made his entrance into Rome, abolished the Roman government and established a secular one and captured Pope Pius VI, who soon died in captivity in Valence, on August 29, 1799. In 1801 Napoleon made an agreement with Pope Pius II establishing Napoleon's Organic Articles of granting the Tribunal and the Corps legislative partial control of the concordat in order to help the state monitor any politically harmful Catholic or Protestant movements or activities. The wound was largely healed in 1929 when Mussolini gave the Vatican back to Pope Pius XI and established it as a country in it's own right in the Lateran Treaty.
Jesus doesn't seem to speak with the same condemnation for the church at Pergamum as he does of the great harlot who's fornications and abominations have been committed with the kings of the earth. I really don't see that Jesus' words concerning the church at Pergamum, or any of the other churches, has any bearing on his words against the great whore Babylon. The Scriptures give a fairly compelling list of evidences by which this great harlot will be known. It ain't the church at Pergamum.
I'm just trying to define some terms and clear up some things that I think may be more, imagining of what it's going to be like, and not actually what the Scriptures tell us about these things.
I was only using the Church of Pergamum as an example of allowing false doctrines in the church as many become blinded to the true doctrines of Christ as they follow after the harlot.
Rev 18:1 And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.
Rev 18:2 And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.
Rev 18:3 For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies.
Rev 18:4 And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
Rev 18:5 For her sins have reached unto heaven, and God hath remembered her iniquities.
