I am not a religious agnostic. Agnostics reject religion but not a higher power. Atheist are those who don't believe in a higher power. To call me a religious agnostic sounds ridiculous to me. I consider all religion to be man made, an attempt to understand and explain the universal force.
I don't have a materialist view of the universe like Atheists. I do believe in Spirituality. Calling me a spiritual agnostic is more suitable.
You can be Spiritual and still pray without invoking a religious based deity.
