All active and retired bishops of The United Methodist Church. The council meets twice a year. According to The Book of Discipline 2000, "The Council of Bishops is…the collegial expression of episcopal leadership in the Church and through the Church into the world. The Church expects the Council of Bishops to speak to the Church and from the Church to the world, and to give leadership in the quest for Christian unity and interreligious relationships."
