Dr. Knight began wrestling with the question posed by his subtitle during the seven years that he represented the Church of Scotland in its mission to the Jews. When World War II interrupted this work, he served a Glasgow Parish, and then, at Knox College, , New Zealand, and presently at Chicago's McCormick Theological Seminary, he worked out the answer to this intriguing book. It was not hard for him to conclude with St. Paul that the answer is ""No"", if the Christian supposes that merely by keeping the Law he is saved. Now is the Christian required to keep the Law in the terms which the Pharisees posed is the Jews of Our Lord's day. It is Dr. Knight's ""Yes"" answer which makes this volume worth the time and thought. His thesis is that Christ is ""kainos"", or the end of the law. When the Christian commits himself to Christ, he is putting himself in total him who is the end of the Law. Dr. Knight insists on the continuity of the Old Testament and the New, and his thesis puts real meaning into the nature of the demand which the Law makes upon us today. Here is a good antidote for that thin version of Christianity which would make of Our Lord a nice, young man. Of special interest is his treatment of the problems posed by the Gospel according to St. John. A great many good when the Clergy have absorbed this book, and it can be placed with profit in the hands of laymen who would steer a Christian course between the twin dangers of more works spirituality. The peculiar grace of the latter chapters is the way in which they deal with the Law-Grace tension in contemporary terms.
