Ecumenical & Interreligious Affairs

Mission Statement

To assist the Bishop and the greater Diocesan community on matters pertaining to ecumenism and interreligious affairs; working together with the many faith traditions in our community to promote dialogue, mutual understanding, friendship and collaboration for the common good.

The Office of Ecumenical & Interreligious Affairs

The Office of Ecumenical and Interreligious Affairs serves as a resource to the Bishop, the offices of the Pastoral Center, and the parishes throughout the Diocese of Orange to promote Christian unity and understanding among faiths; and to foster dialogue and friendship with members of Christian and non-Christian religions. Its work is guided by the teaching and directives of the Second Vatican Council, the Holy See, the United States Conference of Catholic Bishops, and the Bishop of Orange. The Diocese hosts committees consisting of clergy, religious and laypersons to serve as forums for dialogue and to foster ecumenical and interreligious collaboration and cooperation on issues pertaining to the common good.

The Office Provides:

  • Speakers for ecumenical and interreligious subjects, issues and themes
  • Guidance for parishes, ministries and individuals
  • Diocesan events and services that include ecumenical and interreligious leaders and their members
