The Seventh Tradition states: "Every A.A. group ought to be fully self-supporting, declining outside contributions."
While contributions cover each group's rent and other expenses, the Seventh Tradition is essential at every level of A.A. service. It is both a privilege and a responsibility for groups and members to ensure that not only their group, but also their intergroup/central office, local services, district area and the General Service Office remain self-supporting. This keeps A.A. free of outside influences that might divert us from our primary purpose - to help the alcoholic who still suffers.
The amount of our contribution is secondary to our spiritual connection that unites all groups around the world.
