12 Step is too much about God for me. It's all through the literature and language. I think that calling it a Higher Power is an attempt to package the concepts for the atheists and agnostics.
I find the To The Agnostic chapter in the BB condescending as all get-out.
When home visiting my mom in PA I went to some meetings where it was always the Lord's Prayer at close and it was assumed that everyone at the meeting was Christian.
It's not like that here in LA.
I love this guy named Spiritual Al, who's been in recovery for years and founded several agnostic meetings. Old timer, unfortunately not going to be with us much longer. He kept me in AA as long as I needed it.
