My experience was the groups (in the UK) worked on the premise that eventually we'd all believe in 'God' and that Mother Nature, Group of Drunks or whatever, was a holding place until then.
My first sponsor told me often to 'get down on your knees and prostrate yourself and be more humble to God'. Obviously that didn't work well as a relapsed Catholic (I like the 'recovering Catholic' Mike), even my version of the Catholic God wasn't tyrannical.
I then worked with a second sponsor (lovely lady) who had both faith and spiritualism, but didn't press either and encouraged me and other sponsees to have an open mind only and to listen to that small insightful, wise, voice within.
