Dear Father Bruce
The British Orthodox Church is essentially a diocese of the Coptic Orthodox Patriarchate, and so our mission is first of all directed towards British people.
But there is a growing appreciation of the need for something similar in the USA to help the increasing numbers of people who are turning to Coptic Orthodoxy and are English speakers. The Coptic Orthodox Church in the US is looking at supporting English language liturgies, and even American priests to grow American communities within the Coptic Orthodox community and Tradition.
Whereabouts in the US are you? Are you able to visit any Coptic communities and introduce yourself? The bishops in the US are very dynamic and mission directed. There seems to be plenty of scope for committed English speaking Orthodox Christians to be engaged in mission in the US as we seek to be in the UK.
