I just came across this online article from 2002 - http://hss.fullerton.edu/comparative/africa_articles_2002.htm#Pope Shenouda
It notes that:
'Pope Shenouda III said conversion to the Jehovah's Witness faith was a ground for divorce within his church. The only other ground for divorce is adultery.
The Coptic church allows people of other Christian denominations to intermarry, but disapproves of their divorce, which still can be achieved if taken to the courts.
Copts marrying Muslims, who make up most of Egypt's 68 million population, are also excommunicated.'
And I was wondering if it was true that a Copt who marries a Muslim will really be excommunicated? I was a little surprised because I didnt think it was such a big deal if, for example, a Coptic man married a Muslim woman (despite the fact it's very rare - however I do know a few mixed Muslim-Copt married couples). Like, of course ideally we should marry within our religion. But if we marry a Muslim is it true that we'll be excommunicated?
