"What should a Jewish Christian write on if not the Law? But notice that the choice of subject [the ten commandments] means no relapse into mere Judaism, not that need alarm the most Pauline of us. The author knows quite as well as any of us that Mr. Legality will never bring us to the Celestial City and had got over the fallacies of Moralism fairly early in life. She had good opportunities for studying it at close quarters. She knows that only love can fulfil the Law. That, I think, is the answer to a criticism which someone is sure to make of this book; that in most of its chapters we have much more about diagnosis than about cure. In reality , of course, a 'cure' in the sense of some recipe added at the end of each chapter--some 'law to be a fence about the Law' and inveitably breeding more Law--is not really being offered at all. The author is not a quack with a nostrum. She can only point, as in her concluding chapter she does point, to the true Cure; a person, not a set of instructions. Pending that, she is no more inhibited than her ancestors about diagnosis; one might frankly say, about denunciation. A Jeremiad? But should we never read Jeremiads? If it comes to that, should we never read Jeremiah himself? The Canon judges otherwise."
