I don't know about your parents, but my parents are "hardcore" (for lack of a better word) Christians. Please do not say that Christians and Catholics are the same because they're not. Catholics are much more heirarchical and ritual.
Anyways, one thing that my parents do as Christians is respect what another believes, and won't force anyone to go to church and believe in what they believe if that other person doesn't believe it. My dad offers it to my brother all the time, to not go to church, but I guess somewhere deep in him he believes in Christianity... It would explain why he still makes an obligation to go to Church.
Anyways (again), I'm sure your parents will understand, and if they're only reasonable, they shouldn't hold you against your own belief by making you go to church.
