ROCKWELL — Grace Lower Stone Reformed Church will celebrate All Saints’ Sunday this weekend with an outdoor vespers service in the church cemetery, which has been used by the congregation since 1771.

About 500 photo cell-powered grave lights have been placed at tombstones in the historic cemetery. The vespers service, which begins at 5:30 pm Sunday, will be highlighted by the gradual illumination of these lights.

The service, which is open to the public, will give thanks for all the saints of every place and time.

The vespers service is a continuation of the congregation’s yearlong celebration of the 225th anniversary of the completion of the stone church building.

The church is at 2405 Lower Stone Church Road.
