Description: Pope Francis offered a homily at his inaugural Mass which centered on the need for the Church and its members to take up the vocation of "protector," inspired by the example of St. Joseph, for all of humanity and for creation. It means protecting all creation, the beauty of the created world, as the Book of Genesis tells us and as Saint Francis of Assisi showed us. It means respecting each of God's creatures and respecting the environment in which we live. The new Pontiff sees no conflict between protecting creation and the protection of each person. This Monday was Earth Day and today we talk to G. Tracy Mehan about Earth Day – The Papal Edition.
