This interdisciplinary study is the result of an international and ecumenical meeting of nineteen scholars held in New York at Easter 1998: the Trinity Summit. Bible experts examine the spiritual roots of trinitarian doctrine, patristic scholars correct those who continue to misinterpret the trinitarian teaching of the Cappadocians and Augustine, and five scholars examine systematic and foundational issues like the viability of social models for the Trinity. The volume ends with a study of the Trinity in art and the challenge of preaching the Trinity today. Each of the papers prersented here has been circulated to all of the contributors, not only improving the chapters, but also establishing firmer links between the four sections of the book. The international reputation of the participants reflects and quarantees the high quality of this joint work.
