What Is Pietism?

Pietism is something we have discussed many times over the years on Theocast. Four years into recording together, Jon and Justin pointedly revisit the topic in today’s episode. What is pietism? How would the guys explain it to someone visiting their respective churches? How does pietism affect the individual Christian? How does it affect churches and even corporate worship? And what about the church’s tendency to hitch its wagon to politics and social causes--does that have anything to do with pietism?
