At the end of the 3rd century, the Roman Catholics desperately wanted Jerusalem.
Now, I cant tell you better than this video can explain it. This is what enlightened me to the Catholicism creating Islam truth, which was shown to me by a brother in Christ which I met in NYC this past July.
Which made sense since its a fact that the Catholic cult had tried to kill Christians and destroy the Holy Bible before as it is.
Watch this video and pay attention. Its too accurate.

It's only 22 minutes. I haven't done the most research and study on this so I'm not the one to fake. But here it is. Enjoy.
