The Narrow Path Ministries

The claim is that basically for political reasons the Vatican created Islam or at least greatly facilitated it.
So far I've only seen this claim presented by a Chick tract and a Seventh Day Adventist "Amazing Facts" presentation on YouTube.
I know both Chick and the SDA are ultra anti Catholicism. So, before I invest time on it, I'm wondering if anyone knows if there's any validity to this premise or is it purely propaganda?

With this kind of thing, the character of the source of the accusations is often a good place to start. In this case, it doesn't look good: http://en.wikipedia.org/wiki/Alberto_Rivera

A book has been written to debunk the idea from a historical perspective: http://www.prleap.com/pr/41942/

So I'm gonna have to go with "propaganda" on this one.
