“Islam was born in 610 AD, a full 600 years later than Christianity! The Devil had just gotten Pope Boniface III to declare himself the universal bishop of all churches in the world… a claim the eastern orthodox churches never accepted.

In 622 AD, Muslims wiped out the eastern church in a bloody slaughter, leaving the Bishop of Rome to become the dominant, (although apostate) force of Christianity for the next 1000 years.”
