According to the ordinances of the Faith of God, women are
the equals of men in all rights save only that of membership on the Universal House
of Justice, for, as hath been stated in the text of the Book, both the Head and
the members of the House of Justice are men. However, in all other bodies, such
as the Temple Construction Committee, the Teaching Committee, the Spiritual
Assembly, and in charitable and scientific associations, women share equally in
all rights with men.
(‘Abdu’l-Baha, quoted by the Universal House of Justice in
a letter dated May 31, 1988 to a national Spiritual Assembly)
