Originally published at the beginning of the eighteenth-century Enlightenment, a time when rationalist criticism of religious belief was perhas at its peak, William Law's A Serious Call to a Devout and Holy Life succeeded in inspiring the most cynical men of the age with its arguments in favor of a spiritual life. More than simply articulating a set of rules to live by, Law's book examines what it means to lead a Christian life and criticizes the perversion of Christian tenents by the Establishment—whether secular or spiritual—whose real aim is temporal power. With a perface by the Reverend William Sloane Coffin, Jr., whose own direct engagement in social causes still finds inspiration in Law's argument, A Serious Call to a Devout and Holy Life is a book that can still speak to our time.
