The mission of the Office of Canonical Services and Marriage Tribunal is to assist in the judicial dimension of the Diocese. The Diocesan Bishop exercises his judicial authority either directly or through others. It is customary that the Bishop exercise that judicial authority through the Office of Canonical Services and Marriage Tribunal. The duty of that ministry is to provide a forum for the Christian faithful to vindicate or defend their rights.

The office of Canonical Services promotes and protects the obligations, rights and privileges of constituents throughout the Diocese, advises the bishop on matters associated with the various aspects of Church law, provides assistance, research and consultation on all areas of Church Law for clergy and laity, processes and regulates permissions and dispensations relative to marriage, supervises the alienation and suppression of temporal goods of the Diocese, and represents the Diocese in matters of hierarchical recourse to the Holy See.
