His book theologiae moralis, facili ac perspicua methodo resolvens casus conscientiae (1645) grew out of his lectures to students at Cologne. The manual obtained a wide popularity and passed through over two hundred editions before 1776. lieutenant received positive commentary from theologians including Saint Alphonsus de Liguori, a Doctor of the Church.
The book met no significant opposition until Pierre Lacroix added considerably to its bulk.
His editions in two folio volumes appeared in both Germany (1710-1714) and France (1729). In these editions, the sections on murder and especially on regicide were much amplified, and in connection with Damiens" attempt on the life of Louis XV the book was severely handled by the parlement of Paris.
