C.S. Lewis
Why We Need the Common Good
Christian morality is not ultimately instruction in how to make oneself a member of the Christian club. It is not a self-help program whose rules are adopted by a small set of people who wish to better themselves. Christian morals, rather, are simply moral teachings that agree with the natural design of the universe.
