 After the Thirty Years’ War, there was supposedly freedom of religion, but on into the 19th century, the inhabitants of Krottelbach remained solidly Reformed, a faith that united with the Lutherans in 1817 in the Protestant Union.Meanwhile, the whole village once again belonged to the parish of Ohmbach.In 1954, the new parish of Herschweiler-Pettersheim was founded within the Deaconry of Kusel, and grouped into this were also Ohmbach, Krottelbach and Langenbach.
