St. Mark's religion classes help students understand and appreciate that there are multiple ways in which humans make meaning of their existence and condition, and multiple opinions on how best to regulate human behavior and interaction.
Students are required to study at least three religious systems of thought (Judaism, Christianity, and Islam), as well as other meaning-making systems, either religious, humanist, ethical, philosophical, aesthetic, or historical. In both style and substance, the classes are non-sectarian, and similar to what one might find in a college class on religion or philosophy.
