Parish Ministries Council
The Parish Ministries Council is chaired by the Lay Leader and consists of the chairs of all UCP Ministries, the Ministerial Team and representatives of the Trustees Council, HARC, and the Ecumenical Council. Its primary function is communication among its member representatives, through calendaring, brief reports, and informal discussion of program topics and events that arise in the various ministries or councils. In order to accomplish this function, the PMC meets bi-monthly. This forum is a venue for members to raise questions, brainstorm, ask for help, and work together to accomplish the Parish tasks of scheduling, planning, doing, and publicizing events, coordinating overall program development. We benefit by discovering gaps, overlaps, and opportunities to reinforce each other's program goals, while gaining a broader understanding that helps each of us to advance the work of UCP's ministries and councils.

Ecumenical Council
The Constitution of UCP states that the Ecumenical Council "shall have the primary responsibility for establishing, maintaining and enhancing of communications and interactions with our affiliated denominations, and the interfaith community in the Reston area." The "voting membership of the Ecumenical Council shall consist of the four denominational liaisons, each serving for one year during their third year of elected Board service, and one designated Ministerial Team member." The Bylaws further state that "the Ecumenical Council shall have the primary responsibility for maintaining mutual relations with our four governing bodies," which are the Christian Church (Disciples of Christ) Capital Area, the National Capital Presbytery of the PC (USA), the Potomac Association of the UCC, and Arlington District of the United Methodist Church.
