It's not wrong honey. You can be apart of whatever church you want. You're old enough, and you can't FORCE someone to follow a certain religion. All you can do is influence a young child growing up. I can kind of feel for you though: My family is Catholic, and strict ones at that. But I don't like Catholicism and I disagree with our church oftentimes, and I would like to convert and be Lutheran some day. I want a Lutheran wedding, but my mom says absolutely not, that it would break my grandma's heart. I might consider doing a Catholic wedding, simply because my grandma is the kindest and most loving person I know, and she's strict Catholic. But if I don't, my family is just going to have to respect that and deal with it. So do what you want hun!
