Bishops of Overseas Churches
They are styled as for Bishops in the Church of England. The Presiding Bishop of the Protestant Episcopal Church in the United States has the style "The Most Rev the Presiding Bishop".
In the Anglican Church overseas Bishops Coadjutor may be appointed to assist an Archbishop. They have no separate territorial style, and are addressed by name, with the addition of their office. For example:.
The Rt Rev Jonathan Joiner
Bishop Coadjutor of Somewhere
Retired overseas bishops are addressed in the same way as other retired bishops (i.e. Rt Rev John Smith, Dear Bishop).
