This volume in the Westminster Studies in Christian Communication Series is concerned with the problem of connecting Biblical ethics wit the modern world. The author, who is professor of Christian Ethics at Hartford Theological Seminary, sees this problem as being not primarily one of determining what Christian ethics are, but of how the church is to make people hear and understand them. This drives him back upon the origins of Christian ethical teaching in Old Testament and Greek thought. The chapter headings indicate that the major part of the book is give over to a historical survey of the development of the church's teaching derived from these sources. The writer is conscious of the divergence between the mode of thought out of which these ancient systems of ethics arose and the contemporary world. The scientist and the humanist of today, he acknowledges, find the theological categories of the church meaningless. As a survey of these historical developments, and as a description of the problem of communication in our day the book is helpful. The writing is clear and orderly. Whether the result really takes us much further toward the solution of the communication problem, which the author takes as his central concern, is less certain.
