With incredible integrity, prodigious scholarship, breadth of vision, and imaginative velocity, Hans Kung has fashioned a successive string of theological works that are commensurate with the deep wellsprings of Christianity. This helpful and rigorous survey of the 40-year career of this theological giant by Hermann Haring offers an overview of the themes, concerns, and impact of Hans Kung's monumental writings. The author is Professor of Systematic Theology at the Catholic University of Nijmegen in the Netherlands.

Although Rome withdrew Hans Kung's credentials as a Catholic teacher in 1979, he has continued to speak to the hearts and minds of many catholics of all denominations. Haring examines his books under the following themes: ecumenical theology, between church and the kingdom of God, being a Christian as a disciple of Jesus, believing rationally, the inter-religious horizon, the religious situation of our time, and a global ethic and responsibility for humankind. Haring wisely concludes that the touchstones of Kung's theology are intensity, concentration, criticism of ideology, keeping to the point, and continuity.
