The Catholic Church is embracing Islam. There can no longer be any doubt. The Catholic Church is the Whore of Babylon, spoken of in Revelation.
The Catholic Church is open to dialogue with everyone--this ranges from Orthodox Catholics to non-Catholic Christians, to Jews, to Muslims. However, we are not open to changing our own beliefs.
By the way, Revelation is about first century troubles in the Christian world, written in the popular form at the time, which became known as Apocalyptic literature.
