I teach religion in a secular college and have been asked to teach a course on Catholicism.  I’m obviously somewhat limited here so what should I cover over the course of the semester?

Catholicism itself could cover hundreds of courses.  But, that being said, I understand that a secular setting might not be the most appropriate place to discuss doctrine.  I suggest that your best bet would probably be to approach the material in one of three ways that would sidestep the doctrine yet lend it heft and context:  1) historically; 2) by looking at practices, rituals, and beliefs to see how they have developed over time and learn what they say about the faith; or 3) by major thinkers, figures, moments, or ideas to learn why they are important to Catholic identity and self-understanding.

To help you plan further, consult existing course syllabi for more ideas on content and structure.
