In another tract, Is the Catholic Church the Whore of Babylon?, we looked at nine arguments given by fundamentalist Dave Hunt for his claim that the Catholic Church is the Whore of Babylon from Revelation 17–18. His arguments are typical of those used by fundamentalist anti-Catholics and are easily proven wrong. (See that tract for details).

(2) She is connected with the seven-headed Beast from Re…
