Peace sisterfrancesca,
I am sorry to hear your story. But in regards to your question, my belief from what Ive seen in the quran is that we can marry people that arent idolaters, as you stated. There are Christians that fall into either category. Some believe in the Trinity, and thats shirk, while others dont, such as Unitarians. Just because it lists Christians as people of the Book doesnt mean that its talking about all Christians. Its the same as within Islam, there are many sects. If they commit shirk and polytheism, they are idolators and according to quran we shouldnt marry them until they believe, like you quoted.
If your husband already falls in the line of idolatry, seeing Jesus as God, maybe its best to have a talk between yourselves in the best manner. As the quran says
Say "O People of the Book! come to common terms as between us and you that we worship none but Allah; that we associate no partners with Him; that we erect not, from among ourselves, Lords and patrons other than Allah." If then they turn back, say ye "Bear witness that we (at least) are Muslims (bowing to Allah's Will)."
Hope you find your answer.
Peace
Dear Amuslim
Thanks a million for your enlightning answer.
The problem that we have in Islam is that Sunnis and Shias between them make up some 95% of the Muslim world, and we all know that both of them hold ideas that are frankly un-Islamic.
It is no point for the Sunnis to accuse Trinitarian Christians of politeism when they themselves accept Sunnah and Hadith as part and parcel of their religious baggage, which is tantamount to worshipping Prophet Mohammed, even though in an unconscious way.
I don't know much about these Unitarian Christians (I will do some research), but I suspect that they are much closer to Allah than Sunnis and Shias will ever be.
As to my husband, he is a lukewarm Roman Catholic, and the Roman Catholic Church holds on to the dogma that God, because He is Almighty, can do everything, including being one and three at the same time, and that Jesus had both a human nature and a divine nature.
But that does not bother me my husband has always been very laid-back and extremely respectful of my religious views, and has given me total freedom on educating the kids, and all of them have a sound knowledge of the Quran.
Anyway,my husband is a good-natured and God-fearing man, and I sincerely pray that one day I will find him go to Heaven, just by a different path.
The reason why I asked the question in the first place was not not out of concern for myself, but out of concern for girls like that Hina Saleem in Italy who routinely get murdered by their Sunni/Shia relatives because they want to marry someone who is Christian or other.
But again, Sunnis or Shias calling Christians polytheists is like the pot calling the kettle black.
Peace
Sister Francesca
