Great exegesis of the book of Revelation! Not only Protestants believe the whore talks about the Catholic Church, the orthodox and even Sedevacantist thinks that too of the church. While it is true there are sinners and infiltrators existing within the Church (prophesied by Jesus in Matthew 13:24-30), the Catholic Church as a whole, founded by Christ himself is not the whore, but the bride which also produces martyrs and saints to be with Him, Christ. Thank you Dr Brant Pitre for pointing that out. PS for those in schism, especially the Sedevacantist, DO NOT GO OUT (Matthew 24:26) for Christ will not return from the wilderness but to His Temple which He has established on earth.
