I am a christian and I have a fiance that was brought up as a Jehovah witness which is suppose to be categorize as Christianity also, but I know they believe in some things that are different then what I know is true. I told him the difference but since he give up in that religion he wouldn't join a normal christian church with me. He feels as if, if he joins another religion he would be sinning because the teachings are different; though they both Christians and Jehovah witness believe in God and Jesus. I understand how he feels because I was learning about Messianic Judaism ( which is Christians and Jews combined) and was thinking about joining but was not going to take a risk. I want to know is it wrong to go to another Christianity church if they believe in God, Jesus and everything that was said in the bible?
