BOSTON — Parishioners of the St. Frances Xavier Cabrini Church must end their 11-year protest vigil and vacate the shuttered Roman Catholic church, a Massachusetts judge ruled Thursday.

But the Friends of St. Frances, the group that has been occupying the Scituate church day and night since 2004, say they’re not going anywhere. They intend to ask the state court to stay the ruling pending an appeal.

“As of today, nothing changes,” Jon Rogers, one of the organizers, declared late Thursday. “From Day One, we made a promise that we would exhaust every appeal that was available to us, and that includes the U.S. Supreme Court, if necessary.”

The Archdiocese of Boston, which had sued to evict the group, urged protesters to end the vigil and respect the judge’s ruling, which it called “clear and thoughtful.”

In a statement, the archdiocese invited the protesters to “participate and join in the fullness of parish life.”

St. Frances Xavier Cabrini Church was among dozens of parishes closed as part of a controversial plan to restructure the Boston Archdiocese’s debt.

Opponents had said the closures were the archdiocese’s way of paying for clergy sex-abuse settlements, a charge the church has repeatedly denied. The archdiocese blamed the closures on falling attendance, a priest shortage and financial problems.

The Friends of St. Frances have been occupying the now-deconsecrated space since October 2004, with at least one former parishioner holding vigil in the space day and night and supporters holding Sunday services.
