An atheist is someone who does not believe in the existence of a god or gods.
An agnostic is a person who believes that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena; a person who claims neither faith nor disbelief in God.
A theist is someone who believes that at least one diety exists, but not necessarily that religion is true.
There are religions that don't have a 'dogma' that you must accept. Among them are Unitarian-Universalist and Humanistic religions. Let's face it, there really is a difference between "religion" and "deism." I like belonging to a community of "church" but I am not impressed with the concept of theism. Fortunately for me there are alternatives for people to find their own way, to build their own belief systems. But being part of a community, focused on adding value to others lives is a good idea. UU's do that.
... I thought atheism was the belief in no God, or gods? And agnostic belief is that there might be a God or gods, but who really cares? Not the God/gods. But there are religions where there are no God/gods. Or the New Age, which is not very new, where people are gods or godlike or something like that. Scientology is also a religion. Just opening up a whole new can of worms with this post... :)
Actually atheism is not believing in a "higher being." Example: I refer to myself as a CHRISTian as I am a follower of GOD/JESUS CHRIST. I DO NOT go to church. My personal belief is that JESUS came for our salvation but also left us with this amazing thing called FAITH. Since then, (again, my opinion), humans, through the creation of Religion, have done their level best to mess it up.
