What defines the Catholic faith? This introductory course provides an overview of the beliefs of the Catholic Church in 24 units, serving both as an introduction and a means of deepening understanding. Each unit corresponds to an evening session in the context of a faith course and is structured like catechesis. A total of eight major themes (such as Jesus Christ, the Church, etc.) are covered, with three evenings dedicated to each theme. Each evening includes three topics, which are further subdivided, allowing for varying depths of exploration depending on interest or time constraints. The course is aimed at participants, those interested, converts, and speakers who wish to offer their own faith course or plan a lecture or discussion evening on specific topics. It includes guidance from an experienced pastoral worker and school chaplain.
