The 37 senior clergy oppose the appointment of the Rev. Gene Robinson as a bishop and warn his consecration might split the church.
But the BBC reported the Episcopal Church diocese of New Hampshire issued a defiant statement, saying it will go ahead with Robinson's November consecration.
The diocese defended the openly gay bishop, saying he was chosen because of his nearly 30 years of ministry, and his sexual orientation was incidental.
The Archbishop of Canterbury, Dr. Rowan Williams, who called the meeting in London, issued a statement saying the Anglican Church has reached a crucial point, and if the consecration proceeds "the future of the Communion itself will be put in jeopardy."
The diocese of New Hampshire q responded with its own statement: "We look forward to the consecration of Bishop-elect Robinson on November 2, believing God has called him to this ministry, a call confirmed by diocesan election and by the consent of General Convention, in accordance with the Constitution and Canons of the Episcopal Church."
