Boston College graduate Marcus Mescher has written The Study Guide to the Encyclical Letter of Pope Francis: Fratelli Tutti, On Fraternity and Social Friendship (Paulist Press, 2021), which is intended to be a resource for prayer, conscience formation, and discussion in response to Pope Francis’ call to practice mercy, solidarity, and hope. Mescher’s study guide helps readers pray with the text, reflect on it, and look for connections with the canon of Catholic social teaching, and ultimately leads toward action that builds “communities of belonging and solidarity.” Mescher, an associate professor of Christian ethics at Xavier University, is also the author of The Ethics of Encounter: Christian Neighbor Love as a Practice of Solidarity.
