Excellent points. I often wonder if God isn’t allowing the West to be overrun by Muslims for two reasons: to show us again what zeal for ones faith means, and also to awaken the lapsed and complacent Church back into reality, and to give up on secular humanism. God often allowed OT Israel to be overrun, when it turned away from Him. Why would He act any differently today? If it weren’t for the anger I feel at radical Muslims and “moderate” ones for not standing up to the radical ones, I would almost feel pity on them for having such zeal and desire to worship God. Too bad they chose the wrong one. Perhaps this is the point the Archbishop is making.
Yes, and there is a third reason: to draw a sharp distinction between the Islamic way and the Chrisitan way in dealing with adversaries. Future generations will learn from that, at our expense.
