Every single one of my AA meetings ends with the Lord's Prayer, but I've heard a handful of references to Christian dogma in the two and a half years I've been sober and going to meetings. People talk about "God" or their "Higher Power" but we have atheists, agnostics, Buddhists, Catholics, and Jews (and probably Muslims though I don't know any in AA, personally).
I'd make that meeting, if *I* wanted to stay sober.
