The only requirement for AA membership is a desire to stop drinking.
Our membership ought to include all who suffer from
alcoholism. Hence we may refuse none who wish to recover.
Nor ought A.A. membership ever depend upon money or
conformity. Any two or three alcoholics gathered together
for sobriety may call themselves an A.A. group, provided
that, as a group, they have no other affiliation.
"It must never be forgotten that the purpose of Alcoholics Anonymous is to sober up
alcoholics. There is no religious or spiritual requirement for membership. No demands
are made on anyone. An experience is offered which members may accept or reject.
That is up to them."
Bill W. in a Letter to Fr. Marcus O’Brien, written in 1943,
