It is a tragic truth that not all people who hear the words of Christ and the teachings of the Church choose to adhere to them. While some Christians abandon these teachings and traditions altogether, a state known as apostasy, there are many who profess to be Christian while denying the essential truths of the faith. 

Objective: In this course, students will learn about heresies and schisms and how they affect the Church. Students will learn about different heresies, why they exist and what the truths are.
