A new bishop will be consecrated to support UK Christians who support the traditional interpretation of the Bible's view on marriage.
The position is being created by the Global Anglican Futures Conference (GAFCON), an international group of conservative Anglicans who believe marriage is intended to be a life-long union solely between one man and one woman.
GAFCON said the new bishop will minister to churches who have rejected the Church of England "for reasons of conscience".
In a statement, the group said: "...within England there are churches that have, for reasons of conscience, been planted outside of the Church of England by the Anglican Mission in England (AMiE).
"These churches are growing, and are in need of episcopal leadership.
"Therefore, we have decided to consecrate a missionary bishop who will be tasked with providing episcopal leadership for those who are outside the structures of any Anglican province, especially in Europe."
