My sponsor tells this story of a guy that came to AA got sober for about 10 years and then went off to become a devout christian and do lots of work for the church etc, he tells this story like the guy transformed into some kind of AA mutant, i have to defend the poor reformed christain guy in his absence, you know live and let live...trust me you have nothing to fear about being turned into a born again christian unless you yourself decide that is what you want to do when you get sober?!
Try and keep an open mind, also remember that you are knocking on their door for help, as a washed up drunk, and be a little tolerant of people different to you...IMO if you can keep that attitude you will get what you are looking for a lot sooner than later...good luck:-)
