From the village's founding, the villagers of Föckelberg belonged to a parish whose seat was Neunkirchen am Potzberg. Sometime before the 14th century, this parish of the new church (neue Kirche in modern German, the same roots having given rise to the name Neunkirchen) was made partly subject to the parish of Deinsberg (Theisbergstegen). With the permanent introduction of the Reformation into the County Palatine of Zweibrücken about 1537, all subjects had to adopt Martin Luther's teachings as their faith, and this included everybody in Föckelberg. Unlike what later happened in Palatinate-Zweibrücken, there was no further conversion to Calvinism in the County Palatine of Veldenz-Lützelstein, to which Föckelberg belonged as of 1543. Thus, for the time being, all the villagers clung to Lutheranism. From this time comes a story that tells of how the pastor always rode in a calèche from Theisbergstegen to a certain oaktree in the Föckelberger Wald (forest), when he wanted to hold church services in Bosenbach. The people of Bosenbach would likewise come to this tree, the Kalescheiche (Calèche Oak), to pick the pastor up there. This oaktree was felled during the Second World War because it had become dangerous owing to the ravages of age.
