In this edition of Thinking with the Church: Part II of a conversation with theologian Christopher Wells, who is pursuing a doctorate in Sacred Theology at the Pontifical University of St. Thomas Aquinas - the Angelicum - here in Rome. In Part I of our conversation, we explored the Doctrine of Papal Supremacy and the Dogma of Papal Infallibility - both definitively taught by the I Vatican Council in Pastor Aeternus. Here, we delve more deeply into the historical roots and theological origins of the two teachings - but we come to that part of the conversation rather organically - beginning as we do with a discussion of the role of the Pontifical universities in the life of the Church.
