Is there any way Islam could be sceen as a form of Christianity, similar to the way (for those of us in the West) Orthodox Christianity is sceen as a form of Christianity, although perhaps an exotic and form. In the early middle ages it seems Islam was viewed as more of a heresy by Christians than a "Different Religion". What changed? Could a greater Islamic focus on Jesus help, or render the differences no more significant than the greater number of books in the Catholic Bible between Catholics and protestants seem today...or the fact that protestants think Catholics 'worship' or put too much emphasis on Mary, but don't think it's a different religion....so that protestant people would say...."Muslims but too much emphasis on Muhammed...but its 'Christianity....?"
I realize this would take changes in Islamic theology as well, but how could this come about...?
