When Pope Leo XIV, the first pope from the United States, emerged onto the loggia of Saint Peter’s Basilica, he introduced himself to the world as “a son of Saint Augustine.” From his early formation and priesthood to his missionary work and leadership in the Order of Saint Augustine, the life of Robert Prevost has been shaped at every turn by this great Doctor of the Church.

In this unique collection, you will come to know the mind and heart of Pope Leo through his reflections on Augustine’s life, thought, and spirituality, gathered from both before and after his election to the papacy. Included are excerpts from Prevost’s doctoral dissertation, original translations of messages delivered in Spanish, rare passages from book forewords, and references to Augustine in Pope Leo’s early audiences, homilies, and speeches.
