"It is now nearly six years since the house issued its pastoral statement prior to the introduction of civil partnerships in December 2005," the church said in a statement.
"The preparation of that document was the last occasion when the house devoted substantial time to the issue of same-sex relationships. We undertook to keep that pastoral statement under review. We have decided that the time has come for a review to take place."
The Church has been grappling with how to incorporate gay clergy for months, resulting in the formation of a traditionalist group called the Anglican Mission in England, which vowed to create new, gay-free congregations should the Church of England shift course.
