According to all four schools of Sunni law and Shia law, interfaith marriages are condoned only between a Muslim male and a non-Muslim female from the People of the Book (that is, Christians and Jews) and not vice versa.
Islamic marriage rules between Muslim men and non-Muslim women are regulated by Islamic principles.
But there are practically no pastoral resources for Christian-Muslim couples in the United States, despite the fact that according to many estimates, there are now more Muslims in this country than Jews.
Also very important is the fact that in Islam the idea is rapidly gaining popularity of the man being obligated to apply constant pressure on their wives to accept Islam.
(see quote from Romans 10:9 above) In the book of John it says about Jesus A Muslim is someone who stands condemned by God because he does not believe in Jesus.
The Bible makes it clear that if a woman has the freedom to choose her own husband, (which in those times only happens in the rare circumstances that the woman becomes widowed - otherwise marriages were always arranged), they must marry a Christian.
There also exists a minority view that does permit women who have converted to Islam to remain with non-Muslim spouses as an exception to the general rule.
Under Islamic law, if a non-Muslim woman is married to a non-Muslim, and she converts to Islam, the marriage is suspended until her husband converts to Islam.
