OA is not a religious organization. OA members are people of many religious faiths as well as atheists and agnostics. The OA recovery program is based on acceptance of certain spiritual principles. Members are free to interpret these principles as they think best, or not to think about them at all if they so choose.

Many individuals who come to OA have reservations about accepting any concept of a power greater than themselves. OA experience has shown that those who keep an open mind on this subject and continue coming to OA meetings will not find it too difficult to work out their own solution to this very personal matter.
