From 1713 he studied philosophy at the University of Heidelberg, then took up theology and prepared for ordination as priest under the direction of the Jesuits at Strasburg.
Soon after ordination he was appointed parish priest at Waldulm (1726), and in 1730 at Kappelrodeck, but in 1750, on account of severe illness, he was obliged to resign his position.
The Catholic Encyclopedia describes him as having a "keen mind" and being "quick at repartee", but as using "coarse and rough" language.
Historian Ulrich L. Lehner characterizes his style as "offensive" and "ferocious", damaging the Protestant-Catholic relations of his day.
