Three springs...
Someone wrote a book called, The Real AA, or something like that. Meanwhile you can find a lot of info online.
In fact, I did a bunch of postings on here somewhere...
AA was based on an earlier, evangelical movement, called the Oxford Group in England, and Moral Re-armament in the US, and by various other names. It was founded by Frank Buchanon, and they were also called Buchananites. Well-to-do brits would ge together and have meetings, and used many AA principals including anonymity, moral inventories, etc. They wanted to have a personal relationship with god thru fellowship, confession, and striving for 'moral purity.' Of course, it became a cultish movement. Breakaway members, I believe including Bill W., founded AA, using many of the same ingredients. Fascinating.
