With contributions from some of today’s most significant theologians, Engaging Catholic Doctrine is an expression of gratitude to Matthew Levering for his generous collegiality and tireless work to chart a sure path for contemporary Catholic doctrine. Essayists significantly advance the work of Matthew Levering in the areas of Aquinas as a biblical theologian, the doctrine of the Trinity, the significance of sacrifice for authentically Christian worship, the recovery of virtue in moral theology, the theology of Joseph Ratzinger, and much more. In addition to celebrating and honoring Levering’s work, this volume offers new contributions in some of the key areas of theological research today.
