Religious Studies is just one of the various liberal arts majors in which the only possible career path related to your field of study is to become a professor of said subject. You can add Classics, Linguistics, Medieval Studies, and any other major that ends in "studies" to this list. These majors exist only to pad the university's curriculum and squeeze more money out of the today's debt-ridden youth. Don't worry though, these fields of study will make you far more interesting at parties, if your idea of interesting is boring guests to tears with anecdotes about long-dead Popes.
