Since the 1960's, Wolfhart Pannenberg has been recognized as one of the world's foremost Protestant theologians. Currently writing his magnum opus, a systematic theology in three volumes, Pannenberg intends to develop an ecumenical theology which will carry significance for Christians of all denominations. In this volume Stanley Grenz, who studied under Pannenberg in Munich, brings to the English-speaking audience the fullest available exposition of Pannenberg's developed theology, presented within the context of the debate his ideas have generated.
