Yes, the Catholic Church is vibrant with life, and is guaranteed by Jesus himself to last until the end of the age. We keep our converts, they don't go hopping from one church to the next. Accusing the Church as being the whore of Babylon is hate speech. Any serious Bible student knows that Babylon is a code word for PAGAN Rome.
1 Peter 5:13 Peter writes from "Babylon" which was a code name for Rome during these days of persecution. See, for example, Rev. 14:8, 16:19, 17:5, 18:2,10,21, which show that "Babylon" meant Rome. Rome was the "great city" of the New Testament period. Because Rome during this age was considered the center of the world, the Lord wanted His Church to be established in Rome. And there is little point in debating with a revisionist.
