Personally I think "separation of church and state" is the exact opposite of what the First Amendment is really about. It's about freedom of religion, which means practicing whatever religion you want without fear of punishment. So prohibiting prayer in schools is actually a violation of the First Amendment because you're taking away someone's freedom to practice their religion (which is supposed to be protected). Instead, it means that if you want to practice Christianity, you can do that. If you want to practice Islam, or Buddhism, or atheism, you can do that too. The part about Congress not making laws is intended to prevent religions from being declared illegal. Edit: guess I got a little off topic.... :P
