Today on the show, Shaun Blanchard joins me to talk about what changed and what changed at Vatican II, and how the discontinuities hold real meaning for our understanding of ecclesiology (but not necessarily in the way that we might be tempted to think).

Shaun is a Senior Research Fellow at the National Institute for Newman Studies, and the author of "The Synod of Pistoia and Vatican II: Jansenism and the Struggle for Catholic Reform."
