The present study is based on the work of the moral theologist Augustin Zippe Anleitung in die Sittenlehre der Vernunft und der Offenbarung (Prague 1778) and his sermons. Zippe criticizes and integrates their impulses into his own conception of successful Christian life.
Zippe was convinced about necessity to join the ethical requirements based on reason with the requirement based on revelation. The author criticized the strong individualism in ethical conceptions, and maintained his own opinion in the concepts of "moral sense" or "instinct of sympathy" .
