The village church, Saint Quirinus' church, was first mentioned in 1228 as one of the twelve churches around Lake Thun in the Strättliger Chronicle. However, this church was built over the foundation of an older church. The earliest church was probably built in the 8th or 9th century above 7th or 8th century tombs. The original church was replaced in the 11th or 12th century. That church was rebuilt in 1421. The current church was built on the ruins of the 1421 church following a fire in 1727. In 1528, Bern adopted the Protestant Reformation and began imposing it on the Canton. Frutigen, like the rest of the Bernese Oberland, resisted the new faith, but adopted it after the Interlaken uprising was suppressed. The large parish of Frutigen was divided several times but still includes the villages of Schwandi and Wengi which are both part of the municipality of Reichenbach. A Roman Catholic parish church was built in 1959. The Catholic Frutigen parish covers approximately the same area as the medieval parish.
