AA (yes, it is a religion: " The Twelve Traditions also have a decidedly religious tone, referring to "a loving God," "He," and "Himself." 4 The references to God, the concept of the individual powerless against alcohol in the first step, the confession seen in the fifth step, and the idea of "Continuance" in the tenth and twelfth steps come directly from the Oxford Group, which was an evangelical Christian movement (Bufe: 62). The Oxford Group, a "First Century Fellowship," attempted to duplicate the fellowship of the Apostles 10 . AA finds its direct roots in evangelical Christianity, and is clearly a religious organization (Bufe: 82). In spite of AA's straightforwardly religious origins, beliefs, and practices, it presents itself as a non-religious organization and not "allied with any religious organization.")
