Forbidden Crush

i’m a 15 year old sophomore in high school, and i like this boy who is a 16 year old in the grade above me. we’ve been friends since i was in 7th grade, but we’re not as close now. i really like him and he’s told me i was cute before, and my friends say i should go for it, but he’s very christian and i’m muslim. i don’t have a problem with that, except all the girls he’s liked before have been very christian and they would do church things together. i feel like if i tried to ask him out i would get rejected because he wants to focus on church😥 what should i do?
