I've looked at this issue, too. Is this is a sin or a disease? Personally speaking, I have found it easier to accept it as a disease and when I hear other alcoholics describe their problem, the common "symptoms" we all share have reinforced that view. AA offers a programme which is spiritual and certainly doesn't conflict with Christian ideas. The advantage, I would suggest, is that it has a flexible concept of God, which makes it more inclusive. But as others have said, why not try this Christian programme because you may find it provides a good framework for your recovery.
