I respect your beliefs for what they have meant to you. I am not familiar with AA's big book as AA did not sync with my beliefs and what I sought in support. Part of that reason is shown in steps 5 to 7. Just like a great deal of organized religion, these steps on a "face" level imply that something is wrong with you. I am not saying that addiction is not a problem but caution must be used with this type of language. This sounds like the traditional religious tone of "You're a naughty, horrible person and you better do exactly what we say or everything will turn out awful for you."
I did not wake up one day and say, "I really want to develop a drinking problem." Therefore I do not believe I committed a wrong (which is relative to perception.) I have a difficulty that I work with and seek resolution to through acts directed by myself but to say I committed a wrong is self defeating.
Again, I'm not looking to disregard anyone's belief in a god but I often see a fine line between constructive spirituality and destructive blind faith. I have a friend who is a bankruptcy trustee and tells me about people who were given options to help them find a resolution. Instead of acting on their own, they write letters back that say things like, "God will make the choice for me" and "the lord will take care of this." No god actually takes care of anything and their situations become worse than ever when all they needed to do was to believe in themselves first and work on the problem at hand. I would not want to see someone handling addiction in the same way. Even if it does work, an individual would believe something or somebody other than themselves was responsible for the success. There is no gain of confidence and the only thing built is a reliance on something/someone else (like addiction.)
