The blaze broke out Sunday night at Edgebrook Lutheran Church on Hiawatha near West Devon. The fire quickly spread throughout the church and burned through the roof.
Officials said the blaze started in a garbage can at the rear of the rectory. They believe the fire was intentionally set. One person is in custody; investigators say he has admitted to starting the fire.
The pastor and church members managed to save some of charred items inside the church. No one was hurt in the fire.
