Professor Don Antonio Bonato has dedicated much of his scholarly work to the person, works, and thought of Saint Ambrose, Bishop of Milan—pastor, poet, theologian, mystagogue, and passionate preacher. This volume focuses on the spiritual progress of the Christian as presented in Ambrose’s long and complex commentary on Psalm 118. Indeed, Ambrose’s commentary on Psalm 118 reveals itself as a work of extraordinary theological, spiritual, and pastoral richness. Professor Bonato’s interpretative pages demonstrate this excellently, managing to make even the most difficult and rhetorically elaborate passages of Ambrose’s writing immediately enjoyable and accessible. As one reads through the pages of this volume, it becomes clear that Ambrose’s commentary on Psalm 118 is not merely a work of biblical exegesis—though at times it may seem "obscure" or overly "allegorical" to our modern sensibilities—but rather a true journey of faith. It still offers valuable insights today for anyone who wishes to deepen their relationship with God and advance along the path of Christian perfection.
