Karl Rahner (5 March 1904 – 30 March 1984) was a German Jesuit priest and theologian who, alongside Henri de Lubac, Hans Urs von Balthasar, and Yves Congar, is considered to be one of the most influential Catholic theologians of the 20th century. He was the brother of Hugo Rahner, also a Jesuit scholar. Rahner was born in Freiburg, at the time a part of the Grand Duchy of Baden, a state of the German Empire; he died in Innsbruck, Austria. Before the Second Vatican Council, Rahner worked alongside Yves Congar, Henri de Lubac, and Marie-Dominique Chenu, theologians associated with the emerging school of theological thought known as Nouvelle Théologie. Some elements of Nouvelle Théologie were condemned in the encyclical Humani generis by Pope Pius XII. The Second Vatican Council was influenced by Rahner's theology and his understanding of Catholic faith. Source: Wikipedia (en)
