This is a peculiar article. I've been to dozens and dozens of AA meetings in support of various family members. The "God" things was more a notion of a higher power, whatever one interpreted that to be. It was NEVER "Christian" -- notions of God or higher powers are in just about every major and minor faith, everyone from Jews to Wiccans to New Agers.  The one thing I did notice in AA, was that the people who admitted they were powerless over alcohol and opened themselves up to the idea of a higher power (or the Universe or whatever the hell you want to call it) faired better than those who didn't.
