 According to the records in the Kusel Reformed Church's books, Schellweiler belonged to the Kusel church as early as 1567.From 1635 to 1640, records are missing owing to the devastation that the Thirty Years' War wrought upon Kusel and the surrounding municipalities.Beginning with the Reformation, the people were exclusively Protestant, and only about the turn of the 18th century were there once again Catholics living in Schellweiler.
