One of the things that interests me about AA is how far it is actually a 'front organisation' for people to meet with and engage with the God revealed to us in Jesus. The 12 steps program seems to assume the existence of a higher power, and that there is strength available to us to live more wholesome / holy lives if we seek that power out. In fact such an emphasis is healthier than a lot of what passes for Christianity, which can, at times, come down to a celebration of what we have mixed in with a desire to be nice to those less fortunate. (Yes, I know, a gross simplification, but one that offers a nugget of truth). Somewhere along the way the reality of sin - both as an offence to God and its impact on those affected by it - can get lost. By contrast the AA program starts with facing sin's reality and admitting we've messed up.
