How religious is AA?
my experience in general with norcal AA groups is "higher power" is used instead of "God" almost exclusively, people are very careful to not push God / religious understanding / etc
At step 3 you have to turn it over to a "higher power" which is a reflection of the understanding that it is unlikely you, yourself have the power to control alcohol and there must be something "Greater than" you - that can be "physics" that can be "the moon" and a guy who has been sober a very long time in the meeting i go to says his higher power is the "light fixture"
But it really depends on the group. There non-religious modifications to the AA program. They don't say a prayer every 3 minutes. It definitely worth going to a meeting or two just to listen to their stories.
