The word “heretic” gets bandied about online so much these days that it has become almost meaningless, but it remains an important theological concept with serious implications for the life of the church.  

In this unexpectedly sobering Trivia Challenge, Rachel quizzes Erin and Sarah on the meanings and history of major heresies in the church, from Gnosticism to modernism and beyond. 

What even is “heresy,” anyway? Where is heresy mentioned in the Bible? How were the ecumenical creeds specifically formulated to combat heresy? What are good and bad ways to respond to heresy in the church? And is heresy still something we actually struggle with today?
