The Trees of the Field Will Clap Their Hands: An Interview with Dr. Bryan Cross on Creation and the Justice Due Our Fellow Creatures. Dr. Bryan Cross is Assistant Professor of Philosophy at Mount Mercy University in Cedar Rapids, IA. He joins us today to speak about the difference the Common Good and Catholic Social Teaching make when considering "environmentalism" or "nature." Regard as Creation, and seen as a "mutual harmony" between creatures, the flavor of the discussion changes dramatically. Utilizing Pope Francis's encyclical "Laudato Si," the conversation digs deep into why this truly is not an issue that can be contained to or by one "political side."
