Hans Kung is undoubtedly one of the most important theologians of our time, but he has always been a controversial figure, and as the result of a much-publicized clash over papal infallibility had his permission to teach revoked by the Vatican. Yet he is also something like a senior statesman, one of the "Group of Eminent Persons" convened by the UN Secretary-General Kofi Annan, and a friend of heads of government like Tony Blair and President Mubarak of Egypt. In this autobiography he gives a frank and outspoken account of the first four decades of his life. He tells of his youth in Switzerland and his decision to become a priest; his doubts and struggles as he studied in Rome and Paris, and his experiences as a professor in Tubingen, where he received a chair at the amazingly early age of 31. Most importantly, as one of the last surviving eye-witnesses he gives an authentic account of the struggles behind the scenes at the Second Vatican Council, in which he took part as a theological expert.

Hans Kung is Emeritus Professor of Ecumenical Theology at the University of Tubingen and President of the Global Ethic Foundation. He is the author of numerous best selling books including On Being a Christian (Harper Collins).
