The Georgia Supreme Court ruled Monday in a long-simmering property dispute over Georgia’s oldest church, saying a congregation that broke away from the national Episcopal Church four years ago must give back the church’s $3 million property in the heart of downtown Savannah.

The breakaway group has continued to use the sanctuary of Christ Church since 87 percent of its members voted to split from the Episcopal Church in 2007. The Savannah congregation was among dozens in the U.S. that left the denomination over the affirmation of its first openly gay bishop.
