The Lion Returns to Rome : Pope Leo XIV, the Leonine Papacy and the Augustinian Tradition

Mong explores the far-reaching influence of St. Augustine on the papacies of Leo I and Leo XIII and projects how Augustinian thought could shape the emerging priorities of Leo XIV. Through this exploration, the book argues that understanding Augustine's enduring presence in Catholic theology is key to discerning where the Church is headed under new leadership.
