Hans Küng

Hans Küng (pronounced [ˈhans ˈkʏŋ]; born 19 March 1928) is a Swiss Catholic priest, theologian, and author. Since 1995 he has been President of the Foundation for a Global Ethic (Stiftung Weltethos). He is notable for his rejection of the doctrine of papal infallibility. Although Küng is not officially allowed to teach Catholic theology, his priestly faculties have not been revoked. In 1979, he had to leave the Catholic faculty, but remained at the University of Tübingen as a professor of ecumenical theology, serving as an emeritus professor since 1996.

Küng was born in Sursee, Canton of Lucerne. He studied philosophy and theology at the Pontifical Gregorian University in Rome and was ordained in 1954. He continued his education in various European cities, including the Sorbonne.

In 1960, he was appointed professor of theology at Eberhard Karls university, Tübingen, Germany. Like his colleague Joseph Ratzinger (later Pope Benedict XVI), in 1962 he was appointed peritus by Pope John XXIII, serving as an expert theological advisor to members of the Second Vatican Council until its conclusion in 1965. At Küng's instigation, the Catholic faculty at Tübingen appointed Ratzinger as professor of dogmatic theology.
