Defending Mary: Doctrine, Symbol, and the Reality of the Incarnation is a thoughtful defense of Catholic Marian doctrine in dialog with contemporary theology. Drawing on Sacred Scripture, Tradition, and the teachings of the Church, Robert J Gruber examines modern and reinterpretations of Mary's role, particularly those proposed by Sister Mary Aquin O'Neill and other contemporary theologians. The book explores the relationship between doctrine, symbol, human experience, and the mystery of the Incarnation, demonstrating how authentic Marian teaching safeguards both Christological truth and the dignity of the human person. Written with respect for differing viewpoints while remaining faithful to Catholic teaching, Defending Mary invites readers to rediscover the enduring beauty and theological significance of the Blessed Virgin Mary.
