That may be true, but it’s beside the point.
Reformed Christianity is still Christianity; its source is the same as Roman Catholic Christianity. Aside from a few fringe lunatics, everybody recognizes this fact. Both sides of the RC/Prot divide are recognizably Christian, with the Person of Jesus Christ as their root.
Similarly, reformed mohammedanism (if such a thing could exist) would still be mohammedanism. Its source would be the same as that of the shia, sunni, and other existing branches of mohammedanism. Mohammedanisms source is not God; its source is the demon inspired ravings of a caravan raider. No possible reformation can redeem that; no possible reformation can improve it. Reformed mohammedanism would still be evil at its roots.
....”Reformed Christianity is still Christianity; its source is the same as Roman Catholic Christianity.”....
Well actually it’s not. But that’s another argument for another day.
You cannot separate Islam from Mohammedanism.....they are one in the same.
So as I said...and isn’t beside the point...Islam cannot be reformed.
