Major evangelical author with worldwide reputation as both a biblical scholar and systematic theologian

Water Buffalo Theology marked the emergence of a self-conscious Asian Christian theology on the world scene when it was published in 1974. In this twenty-fifth anniversary edition, Koyama thoroughly updates the original, adding an retrospective introduction that records how he has changed his mind on many topics but maintained his position on others. In addition to eliminating several chapters, Koyama also adds one on his "pilgrimage in mission".

Water Buffalo Theology urges readers to abide by the first calling of Christianity -- to become an incarnation of God's love.

Offering a bold intervention in the ongoing debate about the relationship between 'theology' and 'science', Theology, Science and Life proposes that the strong demarcation between the two spheres is unsustainable; theology occurs within and not outside what we call 'science', and 'science' occurs within and not outside theology. The book applies this in a penetrating way to the most topical, contentious and philosophically charged science of late modernity: biology. Rejecting the easy dualism of expressions such as 'theology and science', 'theology or science', modern biology is examined so as to illuminate the nature of both. In making this argument, the book achieves two further things. It is the first major English-language reception and application of the thought of philosopher Hans Jonas in theology, and it makes a decisive contribution to the unfolding reception of 'Radical Orthodoxy', one of the most influential schools in contemporary Anglophone theology.
