I grew up in a similar situation (yours sounds a lot worse than mine though)... and i'd agree with UC it's next to impossible that you'll change his mind. I actually went to a different church from my parents in the end, although my choice was for completely different reasons... however I think in your case it'd be hard to move churches right? nothing else nearby?
At the least I'd recommend lots of prayer. And I mean lots; spend loads of time with God and your Christian faith will mature, and as it does you will begin to make a difference. NEVER let satan try to crush your faith. If you feel under attack, remember where it's coming from. Your faith is dangerous and the enemy will try and use any way he can to destroy what you have. If you can, find other Christians to pray with, preferably not the ones who caused you grief.
Addition: Also remember that Christianity is really little to do with interpretations and theological explanations. It's about a relationship with God, your Father. Many of the greatest Christians I know haven't got a clue about theology, so don't worry about it! Learn to get in touch with God, it's the most important part of the Christian faith.
Praying for you
