This week I've been teaching a course titled The History of Heresy, which my students have seen as an incredibly fun and informative way to learn about the formation and defense of Christian orthodoxy. We covered the good, the bad, and the ugly of church history. We learned about how the church came to discern the difference between the true gospel and false ones, between the biblical Jesus and the Jesus of inventive fantasy, between the church's rule of faith and the foreign philosophies that Christianity was sometimes expressed in. This fascinating study also led us to look at the various creeds of the early church.
