The most used definition of religion is, and this is not the only definition, "Any specific system of belief, worship, conduct, etc., often involving a code of ethics and a philosophy." What that means to me is that if we believe in a higher power, we also act and understand like we believe in that outside force that connects us to the infinite. In my humble thought process, if I call someone "doctor" then I accept his or her credentials and allow him or her to heal or cure.
