On October 11, 2012 I presented the Meeter Center Lecture, "'Lift Up Your Hearts': John Calvin's Catholic Faith." (It was a delicious irony that I was delivering this talk on Calvin's Catholic faith on the 50th anniversary of the beginning of Vatican II--when the Roman church finally began listening to him!) I'm making the talk available via Scribd. (Audio may be forthcoming.)
I was going for "winsome polemic" here: there are parts that will push different buttons for different communities, including my own. I hope the provocations can be received in the spirit they were intended: as an invitation to reconsider (or better, remember) what it means to be "Reformed."
