Book excerpt: The twentieth-century patristics movement that contributed theologically to the Second Vatican Ecumenical Council is generally well known. Less well known, but no less important, is the similarly dynamic return to the ancient ecclesial sources that took place in nineteenth-century theology, which profoundly shaped the Catholic articulation of the relation of faith and reason, the development of doctrine, the Immaculate Conception of the Mother of God, and the nature of the Church. In Engaging the Church Fathers in Nineteenth-Century Catholicism, Joseph Carola, S.J., tracks the theological movement of the Scuola Romana, a contemporaneous, interconnected return to patristic sources pursued by Jesuit theologians at the Roman College—Giovanni Perrone, Carlo Passaglia, Clemens Schrader, and Johann Baptist Franzelin—and their precursors, interlocutors, and intellectual progeny, including the Tübingen theologian Johann Adam Möhler, the Oxonian John Henry Newman, and the Cologne theologian Matthias Joseph Scheeben. Situating these seven theologians’ lives and labors within the broader historical context of nineteenth-century Catholicism, Carola introduces readers to a rich theological world rarely explored, providing both biographical depth and attentive distillation of their writings, methodologies, and impacts. As Carola shows, these extraordinary theologians engaged the Church Fathers and the Church’s entire tradition with intellectual rigor, revitalizing the nineteenth-century Catholic Church at her very heart and providing, in turn, a refined patristic methodology and faithful theological vision that are just as vital for the Church in the twenty-first century as they were in the nineteenth.
