Pretty much. From the big book of Alcoholics Anonymous, "Well, that's exactly what this book is about. Its main object is to help you find a Power greater than yourself that will solve your problem."

and

"Even so has God restored us all to our right minds. To this man the revelation was sudden. Some of us grow into it more slowly. But He has come to all who have honestly sought Him. When we drew near to Him He revealed Himself to us."

It is true that oftentimes newcomers are told that they can have their own interpretation of a less exact 'Higher Power' such as God equaling 'good orderly direction' or even 'group of drunks' - but then we are told to turn our will and our lives over to the care of God and suddenly, the 'group of drunks' acronym no longer works.

That is not to say that AA can't work for the atheist or agnostic, as long as they are willing to do some mental gymnastics to get over the God aspect. I was and remain an atheist and was what the AA Big Book calls a 'real alcoholic'. I have managed to stay sober for some twenty-three years now. I found that for me, getting honest with myself was the key, and I couldn't do that by pretending to have a belief where one didn't exist.
