How Much Religeon Should Be Discussed In Our Public Schools?

12. Would need to know a little more about the context

But certainly any review of the history of Medieval Europe would be very incomplete without a discussion and understanding of the role of the church in civil society and politics. Understanding that role would entail knowing who's who in the church hierarchy (why did this ruler ignore a bishop, but then he capitulated when a cardinal got involved); what sacraments are and why getting cut off from them was considered a big deal; and how the church calendar influenced society's calendar, to name just a few.

The context matters if the teacher is presenting this information as being just as true today as it was in the 12th Century (or whenever during the Medieval period). But if the information is presented in a way that makes it clear that we don't think about these things the same way today that the rulers and people of Europe did then, then I don't see a problem.
