Hans Kung
Born in Lucerne, Hans Kung (1928-2021), the Swiss Catholic theologian, was the eldest of seven children; his father managed a shoe shop. He became a Catholic priest and theologian. The most important contribution of Hans Küng is widely considered to be his work on church reform and his role in initiating interfaith dialogue and global ethics—particularly through his concept of a “global ethic” (Weltethos).
Here’s a breakdown of his most influential contributions:
1. Critique of Papal Infallibility (1971)
Küng’s 1971 book, Infallible? An Inquiry, was a landmark theological challenge to the doctrine of papal infallibility as defined at the First Vatican Council (1870). He argued that the concept lacked solid biblical and historical foundation and was a major obstacle to church reform and ecumenism.
This book led to the revocation of his license to teach Catholic theology in 1979 by the Vatican, but he remained a priest and continued teaching under the broader university. For decades Swiss theologian Hans Kung has been in the forefront of dialogue between Roman Catholic and Protestant Christians of orthodox creeds. In the academic arena he has heartily joined in the search for contemporary ways to express Christian faith. When he was dismissed as an official theologian of the Roman Catholic Church, on the ground that his writing cast doubt on several of the most basic doctrines of his church, churchmen around the world in a quandary about the commitment of the Catholic Church to ecumenical dialogue.
Impact: However he became a symbol of theological freedom and critical engagement within the Roman Catholic Church.
2. Leadership in the Global Ethic Project (1993–2021)
Küng’s most globally influential work may be the Declaration Toward a Global Ethic, adopted at the 1993 Parliament of the World’s Religions in Chicago. He believed that the world’s major religions share a core of ethical values, such as:
Human dignity
Golden Rule (treat others as you wish to be treated)
Commitment to peace, justice, and sustainability
This work aimed to lay the moral groundwork for peaceful coexistence in a globalized, pluralistic world.
Impact: Küng’s “Global Ethic” initiative became a key resource for interreligious dialogue, ethics in politics and business, and UNESCO’s intercultural programs.
3. Promotion of Ecumenism and Interreligious Dialogue
Küng wrote extensively on Christian unity (The Church, Christianity and the World Religions) and emphasized the need for dialogue with other faiths, particularly Judaism, Islam, Hinduism, and Buddhism. He believed:
"There will be no peace among the nations without peace among the religions. And no peace among the religions without dialogue between the religions."
Impact: He was a theological bridge-builder in a world divided by religious conflict.
4. Modernizing Theology and Making It Accessible
Küng also made major contributions through works like:
On Being a Christian (1974) – a major modern Christology accessible to lay readers.
Does God Exist? (1978) – a comprehensive argument for belief in God in dialogue with atheism and secular philosophy.
Christianity: Essence, History, and Future (1994) – a sweeping analysis of Christian history and its future relevance.
Impact: He helped reframe theology for a secular and postmodern audience.
