Please help? My dad won't accept my beliefs?

My mom is a protestant and my dad is a Christian, coming from a very strong Irish/Christian background (to put it in perspective, his parents go to Church at 6 am every day of the week, even when they're on vacation, etc). My mom is a lot more relaxed about her religion, she didn't go to Church as a kid, only on major holidays like Christmas and Easter, and she has been baptized and confirmed. I've been raised Christian, and my family has a "rule" that we all go to Church on Sundays. Not an insanely strict rule, there are exceptions every once in a while, but for the most part, I need to be at Church with them every Sunday. I've recently discovered in the past year or so, that I don't really believe in the Church. I believe in God and most parts of Christianity (excluding things such as "gays shouldn't get married", and "Women should serve men"), but not the Church. I've tried to participate, but I don't like it. It doesn't feel right. And my Church is intensely Christian- they have people chanting and praying and singing, and...I know this will sound wrong, but it feels a little "devil- worshipping"-ish. They're obviously not worshipping Satan, but I'm uncomfortable, and it's just too much for me to handle. Also, I don't believe that I need to be at a certain institution every Sunday to proclaim my love for God. I've told my Dad about all this, and he will NOT stand it. I always present these beliefs in a factual manner (not belittling or talking bad about the Church by any means), he tells me that he's really disappointed in me. He always says that if I don't go to Church I won't be allowed to leave the house, he won't let me drive, no more activities outside of school (like art classes, which I NEED for college applications next fall), and he'll send me to Catholic school again. I'm just gritting my teeth and going to Church nowadays, but I feel so disrespected because he won't let me believe what I believe. And this is something that I truly believe, it's not just a way to get out of going to Church. It makes me really sad to know that he won't accept my beliefs, when I know that he accepts everything else about me and loves me. Please help, how can I get through to him?
