This is liberal socially-minded Protestantism at its best, by an author primarily concerned with the effect of our urbanized society upon the soul of man. His is a ringing call to the Protestant churches for a more vigorous and thorough-going attack upon entrenched evil. The chapter headings indicate the spirit and content of the book:- ""Why does Protestantism hesitate?."" ""The Church must understand the social and economic causes of sin and misery."" ""The Church must awaken the conscience."" ""The Church must bring the judgment of conscience upon society."" ""The Church must establish friendship for labor."" ""The Church must establish a world of Protestant union."" ""The Church must strive to realize the will of God in society.""... This challenging and provocative book is based upon the author's lectures under the Walter Rausehenbusch Lectureship Foundation and does credit to the memory of that great prophet of the social gospel.
