Overeaters Anonymous has no religious affiliation but it does have a spiritual basis. OA doesn’t tell us we have to believe in God, but it suggests we be willing to consider the idea that a power greater than ourselves could restore us to sanity. We are invited to define that power however we wish and relate to it in whatever way works for us. OA only suggests that we remain open to spiritual growth and show tolerance for others by neither criticizing nor promoting specific religious doctrines in OA meetings.
People of all faiths are welcome. Even atheists and agnostics are welcome in OA and have found recovery.
