[Antoninus]

Orthodox Christians have been defending themselves against Islam since Heraclius. The Catholics were late comers to the struggle and sometimes did the struggle harm.

Uh, if you asked Heraclius what Chuch he belonged to, would he respond "the Orthodox Church?" You do know that the Orthodox and Catholic Churches were one prior to the schism of 1054 AD, right?
