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. Biblical experts examine the scriptural 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. The international reputation of the participants reflects and guarantees the high quality of this joint work.
