Moral Theology: Getting Started

Moral thought begins in the conscience informed by natural law. The Ten Commandments and Jesus' life are the foundations for Catholic moral action, which has resulted in the Church's strong social teachings.

Our library consortium is transitioning to a new Library System and search engine called CLICsearch.


Updating hyperlinks in progress:



  • If a link to a catalog record for a book or media item does not currently connect in this guide -- search for it again using CLICsearch on the library's website at  Search for an item by its title, author, or keywords.  Now you will find up to date call numbers, locations, as well as find which CLIC libraries own your item.

Catholic Moral theology, known as Christian Ethics in non-Catholic contexts, encompasses Roman Catholic social teaching, medical ethics, sexual ethics, and moral virtue and theory.

Moral theology seeks to define and address things such as the different methods of moral discernment, the definitions of right and wrong, good and evil, sin and virtue, etc.

Studies in moral theology are numerous and wide-ranging. The literature for research is very large and diverse.
