, the First Amendment protects us from the establishment of religion. In fact, if the Supreme Court has to decide a case involving the First Amendment, they use three guidelines:
1: Is the government actively endorsing religion?
2: Is the government forcing people to accept a religion?
3: Is the government giving unfair treatment to one religion that is not offered to others?
Putting religion and government together violates at least two of those (most likely all three) and is therefore unconstitutional.
