Staff and Leadership

All church members play a role in governance, from decisions in parish life to our national policy-making body, the General Convention. Lay and ordained people, together with the church's bishops, share the responsibilities of ministry, oversight and legislation. The ministers of the church are lay persons, deacons, priests and bishops.
