The lay faithful and, specifically, catechists, should become familiar with Canon Law because Canon Law guides the Church and protects the rights of the faithful. It spells out how the Church is to conduct itself. In this Course, you will use Canon Law in all of the lessons on the Sacraments.

In the Western Church, Canon Law is known as the Code of Canon Law; in Latin it is Codex Iuris Canonici. In the Eastern Catholic Churches, Canon Law is known as the Code of Canons of the Oriental Churches; in Latin it is Codex Canonum Ecclesiarum Orientalium.
