The World Council of Churches' Commission on Faith and Order coordinates theological discussion that promotes the unity of the Christian church. Roman Catholic and other non-WCC representatives are among the 120 plenary commission members, and a 30-member standing commission meets to oversee the study agenda. It has released documents on topics such as ecclesiology, theological anthropology, reconciliation, and violence and peace. "Baptism, Eucharist and Ministry" (1982) remains one of its most widely known statements, used by numerous churches as a reference in their own ecumenical dialogues. Finally, the Faith and Order Commission works jointly with the Pontifical Council for Promoting Christian Unity to develop materials for the annual Week of Prayer for Christian Unity, which highlights the role of common prayer as one of the most tangible and widespread ecumenical practices around the world.
