Father Hans Küng (born March 19, 1928 in Sursee, Canton of Lucerne), is a Catholic priest, a Swiss theologian, and a prolific author. Since 1995 he has been President of the Foundation for a Global Ethic (Stiftung Weltethos). Küng remains a Catholic priest in good standing, but the Vatican has rescinded his authority to teach Catholic theology. Though he had to leave the Catholic faculty, he remained at the University of Tübingen as a professor of Ecumenical Theology, serving as Emeritus Professor since 1996. Neither his bishop nor the Holy See has revoked his priestly faculties.
