The Advisory Commission on Ecclesiastical Relations was created by the authority of the General Convention in 1931 in its revision of Canon 59(v)(v). The National Council subsequently added the Advisory Commission to its bylaws to replace the earlier Committee on Ecclesiastical Relations, that had been set up in 1927 to consider matters of expanding ecumenical relationships.
By 1935, reduced budgets made it necessary to discontinue the salaried officer. A 1937 revision to Canon 59 dropped the Commission and left oversight of this work to the Presiding Bishop and Council. The Commission and an unsalaried officer were continued with a small budget allocation. The broader ecumenical purview of the Commission was extended by Bishop Tucker in 1939, who renamed the body as the Advisory Council on Ecclesiastical Relations.
