"This series is not for the lazy. Each major theologian is examined carefully and critically- his life, his theological method, his most germinal ideas, his weaknesses as a thinker, his place in the theological spectrum, and his chief contribution to the climate of theology today. The books are written with the assumption that laymen will read them and enter into the theological dialogue that is so necessary to the church as a whole. At the same time there are carefully enough designed to give assurance to a Ph. D. student in theology preparing for his preliminary exams."--Editors Preface.
