Father Hans Küng, the prominent and sometimes controversial Swiss Catholic theologian, died peacefully in his sleep in the university town of Tübingen, Germany, where he had lived and lectured since 1960, said a spokesman for his Global Ethic Foundation. He was 93.
Father Küng was one of the most outspoken Roman Catholic theologians and one of the sharpest critics of St. John Paul II and Pope Benedict XVI. He had worked with and studied with Pope Benedict, then-Father Joseph Ratzinger, in Tübingen in the 1960s.
Along with Father Ratzinger, Father Küng was one of the youngest theological experts advising bishops at the Second Vatican Council in 1962-65, but not long after the council he stirred controversy with his views on papal infallibility.
