Who We Are

Purpose of CADEIO

CADEIO stands for the Catholic Association of Diocesan Ecumenical and Interreligious Officers. It was formerly known as NADEO, the National Association of Diocesan Ecumenical Officers. CADEIO was established to: 1) stimulate the exchange of ideas, experiences and networking among the Ecumenical Officers of the arch/dioceses in union with Rome; 2) promote programs that further the work of Christian unity and interreligious cooperation; and 3) cooperate with the Bishops’ Committee for Ecumenical and Interreligious Affairs of the United States Conference of Catholic Bishops, and with other ecumenical and interreligious agencies.


CADEIO is a voluntary association of Ecumenical Officers who serve at the request of their arch/diocesan bishop as a delegate for ecumenical and interreligious affairs. Our organization is listed in the Official Catholic Directory. The final authority of CADEIO is the General Assembly, which meets at least once a year.  Between meetings of the General Assembly CADEIO is guided by the Board of Directors and the Executive Committee. The Board consists of sixteen regional members — one elected from each of fourteen geographical regions in the country, one from The Personal Ordinariate of the Chair of St. Peter, and one member representing the Eastern Catholic Churches in the United States. The Executive Officers consist of the President, Vice President, Secretary, and Treasurer. There is no paid staff for CADEIO. The Executive Officers and the Board of Directors serve the organization without remuneration.

“In many ways this organization [CADEIO] has an impressive record of service to the Catholic Church’s efforts in promoting Christian unity…you have celebrated ecumenism and contributed to its development in the United States. You have responded with commitment and dedication to the challenge of ecumenism.

Edward Cardinal Cassidy, President Emeritus, Pontifical Council for Promoting Christian Unity
