 Relsberg originally belonged to the Glan chapter within the Archbishopric of Mainz, and in terms of ecclesiastical organization was tied to Reipoltskirchen.That still held true after Philipp I of Westerburg-Leiningen introduced the Reformation in the 16th century, at the latest.In those days, all the villagers were, under the principle of "cuius regio, eius religio", followers of Martin Luther’s teachings.
