Is AA Just For Christians?

At the beginning of every meeting of my home group, we read, "AA is not allied with any sect, denomination, politics, organization, or institution; does not wish to engage in any controversy, neither endorses nor opposes any causes." This statement makes me feel good. As a person with strong spiritual, social, and political convictions, I wouldn't have lasted a month in the program if AA had supported a political movement, economic interest, or organized religion. As it is, I've enjoyed two years of sobriety, spiritual growth, and amazing personal development in AA. I am past retirement age, but have never had a happier two years in my life.
