First published in 1906, this book considers the concept of atonement and suggest that the doctrine of atonement is not an artificial theorem or an inexplicable or unethical dogma, but that it has roots in the foundations of all human life. Lofthouse further argues that the doctrine of atonement is the highest expression of the law of all moral and social progress; and that ethics in itself is of little use as a practical science, unless completed by atonement.
