In We Live in a Castle , Fr. Glenn uses the ancient story telling technique of parable to illuminate an esoteric topic— ecclesiology : the study of the history, nature and mission of the Church. Very few Catholics are even aware that such a field of study exists. Yet the concepts in ecclesiology are foundational to all other Church teaching. In this work, Father opens them up to any lay person looking for an entertaining, informative read. Along the way, he provides many things for a caring Catholic to think about.
