AA is a program created by a "whacko". If there were a "GOD" he certainly would have nothing to do with this sick cult. Higher Power is just another name for "GOD" and if you read the stupid "Big Book" you will see "God" mentioned exactly over a hundred times. So it's not spiritual. It is a religious cult.
And you can get much factual and scientific research data at orangepapers.com as to the origins and standing of this SICK CULT.
