CADEIO stands for "Catholic Association of Diocesan Ecumenical and Interreligious Officers."

This site is intended to serve those delegated as Ecumenical/Interreligious Officers in each Catholic Diocese in the United States, to whom is given the care of Christian Unity and understanding among faiths. Further, it is intended to familiarize others interested in the field of Ecumenism and Interreligious Dialogue with the aims and work of CADEIO.
