Karl Rahner, SJ (March 5, 1904 — March 30, 1984) was a German Jesuit and theologian who, alongside Bernard Lonergan and Hans Urs von Balthasar, is considered one of the most influential Roman Catholic theologians of the 20th century. He was born in Freiburg, Germany, and died in Innsbruck, Austria. Before the Second Vatican Council, Rahner had worked alongside Yves Congar, Henri de Lubac and Marie-Dominique Chenu, theologians associated with an emerging school of thought called the Nouvelle Théologie, elements of which had been criticized in the encyclical Humani Generis of Pope Pius XII.
