I know several people who were led back to their faith through 12 Step programs.
The origins of 12 step recovery are Biblical in nature. The early 1900’s a Lutheran pastor named Frank Buchman, who, after a series of events following seminary, began what was called the Oxford Group Movement at Oxford University in England (not to be confused with the Anglican “Oxford Movement” which was ecclesiastical and liturgical in nature). Basically dedication to Christ, acknowledgement of past shortcomings, confessing your shortcomings / transgressions to another and then carrying this message to others.
The movement spread through “house meetings” and were often supported by churches. They were quite popular as a method of curing what we would call sinful behavior. Bill Wilson’s friend Ebby got sober through an Oxford Group and carried the message to Bill. When Bill was on a business trip to Akron, the “list” he was calling were for Oxford Groups which wound up connecting him to Dr. Bob.
They began attending Oxford Group meetings, and the church people, as church people are wont to do, began seeing the drunks as “those poor drunks” and conveying a sense of prideful direction. The drunks, as drunks are wont to do, got their own coffee pot and started their own meetings. This was the official beginning of what we know as AA.
If you read some of the historical material, like “Dr. Bob and the Good Oldtimers”, you’ll see Dr. Bob said there was nothing in the 12 Steps that couldn’t be found in the “good book”, particularly the Gospels, The Beatitudes and Book of James (particularly chapter 5).
I think the biggest difference between AA and church is that those who “get” recovery see their lives as dependent on living a spiritual life, where as most church people I meet are unaware of their need of living a rigorous spiritual life due to their sinfulness. Sometimes resulting in prideful empathy without realization the addict is often on more firm spiritual ground…
So, that’s a long way of saying the Church has everything one needs to end a life of addiction, but those looking to recover will often have a difficult time finding a group of people to connect with for support in their journey.
Hope that helps.
