A quote from Father Joseph Fessio S.J. on Radio Blogger, 5 January 2006

If we look at the demographics [...] I don't see any other issue for Europe, or any result, than looking like North Africa, you know? Algeria, Morocco, Libya, Egypt, I mean, they were all Christian, thriving Christian communities, you know, in the early Church. And now, you can’t profess your faith there. You can’t bring a Bible in some of those countries. [...]

Jihad can be largely interpreted to be a spiritual struggle. But the text themselves talk explicitly about the extension of Islam to all peoples, and they allowed either to accept, or if they reject it, [...] you become dimis, or second class citizens, or subject citizens to Islam. Actually, it’s interesting. I was in Rome, actually Castel Gandolfo, the Pope’s summer residence, in September of 2005. His former students met with him, and the topic of our meeting was the Islamic concept of God, and its consequences for a secular society. And we had two people there who gave talks, one of them extraordinary, a man named Kalil Safir Kalil (?), who is an Egyptian born Coptic Catholic, Lebanese Jesuit priest [...] And he quotes key Islamic leaders saying the following: Because of your religious tolerance in Europe, we will overtake you. We will be coming into Europe. Because of our religious beliefs, we will conquer you. I mean, there should be no doubt about it. [...].
