Peace on Earth: The Renaissance of Christian Humanism by Edwin Jones (Resource Publications, £18). This enthusiastic book whistles a familiar tune. If we want decent, value-driven societies then religion is a useful lodestone. Neither individual consciences nor the ethical choices of idiosyncratic cultures can, so the theory goes, overcome the grubbier side of human nature. God is a much better bet and Christian humanism – understood here as a commitment to loving the Creator and loving your neighbour – provides a guide through the thicket. Jones looks at various figures (including Robert Schuman, Pope John XXIII and Pope Francis) to hammer home his point.
