S.A.E. is organized democratically. Its board of directors (president, executive council, council of local groups) is elected by its members. Local groups share the aims and methods of the association and are autonomous with regard to the programming and the carrying out of their activities.

Roman Catholic, Protestant, Anglican, Orthodox and Jewish lay men and women constitute the members of the association; priests, ministers, monks and nuns join as friends.

Consultants and a standing committee of biblical scholars and theologians support the association. Members of both these groups come from different religious denominations.

Inside S.A.E. mixed groups have been constituted in order to work on theological research, ecumenical teaching and interconfessional marriages; the Theological Group, made up of Roman Catholic, Protestant and Orthodox theologians, is still at work.

S.A.E is autonomous both in its organization and economically. Directors and collaborators are voluntary. S.A.E., for the most part, pays its way thanks to the yearly subscriptions of its members.
