Fr. Thomas Hart, O.S.B., chair of the Religious Studies Department, was invited to address The Theosophical Society of Pittsburgh on Dec. 11. The topic was the Catholic Church at the 40th anniversary of the Second Vatican Council. Special attention was given to the influence of Nostra Aetate (The Declaration on the Relationship of the Church to Non-Christian Religions), with the Church's dual commitment to both evangelization and dialogue with the world's great religions.
