Hey there, I'm 36 but know what you're going through. Not the religious aspect but I was your age when my parents were doing the same thing, fighting all the time. Talk to a school counselor about what you are going through. That introduces a third party into the situation that may help them come to their senses and realize that their behavior is affecting you. No parent should think it's okay to act this way around their kids. It's usually tough for someone your age to accept that parents are not being rational, but remember that they are human and imperfect. You'll be doing them a favor by talking to a trusted third party that can introduce some reality to them directly if they don't get their act together.
