Truro Church in Fairfax and The Falls Church in Falls Church plan to place themselves under the leadership of Anglican Archbishop Peter Akinola of Nigeria, who has called the growing acceptance of gay relationships a "satanic attack" on the church.

Truro rector Martyn Minns was consecrated a bishop by the Church of Nigeria earlier this year to lead Akinola's Convocation of Anglicans in North America.

"This has been our spiritual home, so separating is very hard," Minns said at a news conference announcing the parishes' decision. "There's also the promise of a new day. A burden is being lifted. There are new possibilities breaking through."

Virginia Bishop Peter Lee, a centrist, had won praise even from his critics for his extensive outreach to all sides in the conflict. He said Sunday that the votes "had compromised these discussions and have created Nigerian congregations occupying Episcopal churches."

Four other Virginia parishes have left, and eight more are voting or will vote soon whether to follow suit, according to the Virginia diocese. None is as eminent as Truro and Falls Church, however.

A lengthy and expensive legal fight is expected over those historic church properties, which are worth millions of dollars. "We fully intend to assert the church's canonical and legal rights over these properties," Lee said in a news release, calling it a "sad day for the church."

The Episcopal Church, the U.S. wing of the global Anglican Communion, has been under pressure from traditionalists at home and abroad since the 2003 consecration of the first openly gay bishop, Gene Robinson of New Hampshire.

Under Anglican tradition, Akinola's move into Episcopal territory amounts to an invasion, since archbishops agree not to start churches outside the borders of their own region. Episcopal Presiding Bishop Katharine Jefferts Schori will consult with her advisers on how the denomination should respond, said Bob Williams, the national Episcopal spokesman.

While theological conservatives are a minority within the 2.2 million- member U.S. denomination, their protests have had an impact.

Ninety per cent of Falls Church parishioners and 92 per cent of Truro members who cast ballots in the last week supported cutting ties with The Episcopal Church, parish leaders said.

The loss is spiritual as well as financial; the parishes are among the largest and most vibrant in the diocese, together claiming more than 4,000 members.

"It was a very, very emotional time," said Jim Oakes, Truro's top lay leader, who supported the split. "In some ways it's like a death in the family."

Nationally, Episcopal researchers estimate that at least one-third of the nearly 115,000 people who left the denomination from 2003 to 2005 did so because of parish conflicts over Robinson.

Seven of the 100 U.S. Episcopal dioceses have threatened to break from the denomination, but have so far stayed put. The closest any have come to leaving was a vote earlier this month in the Diocese of San Joaquin, in Fresno, Calif., endorsing a first step toward seceding. But that diocese must take a second vote next year before they can formalize a split.

The feud has been far more damaging to the 77 million-member Anglican Communion.

Most overseas Anglicans believe gay relationships violate Scripture and contend liberal interpretations of the Bible are far outside the bounds of mainstream Christian belief.

Struggling to hold the communion together, Archbishop of Canterbury Rowan Williams, the Anglican spiritual leader, has said that the communion may have to create a two-tier system of membership, with branches that ordain partnered gays given a lesser status.

Akinola is among the conservatives who aren't waiting for a negotiated solution.

In a statement Friday, Canon Kenneth Kearon, secretary general of the Anglican Communion, said that the archbishop of Canterbury has not "indicated any support" for the mission.
