In this contemporary classic originally published in 1963, Paul Lehmann answers the central question posed time and again to Christians throughout the ages: what am I as a believer in Jesus Christ and a member of his church to do? Lehmann argues that while principles for moral action can be rules of thumb, there are no absolute moral norms beyond the general norm of love. Lehmann contends that Christians are to act in every situation in ways that are consistent with God's humanizing purposes, but what that means changes from context to context and requires strong, faith-shaped discernment.

The Library of Theological Ethics series focuses on what it means to think theologically and ethically. It presents a selection of important and otherwise unavailable texts in easily accessible form. Volumes in this series will enable sustained dialogue with predecessors though reflection on classic works in the field.

Building on a long career in the field of Christian ethics, Paul Lehmann examines the role of the Ten Commandments in Christian life, contending the Decalogue describes rather than prescribes human life as God would have us live it. Lehmann is the author of Ethics in a Christian Context and Transfiguration of Politics.
