Below is an excerpt from 'On Faith,' an Internet feature sponsored by The Washington Post and Newsweek. Each week, more than 50 figures from the world of faith engage in a conversation about an aspect of religion. This week's question: What do you think of the American Humanist Association's new 'Godless Holiday' campaign? The ads, displayed on transit systems in five major U.S. cities, will say: 'No God? ... No Problem! Be good for goodness' sake. Humanism holds that you can be good without a belief in God.' Is this another front on the so-called secular 'war on Christmas'? Or is this another example of the pluralistic strength of America? And would you agree with the premise, 'No God, no problem?' Cal Thomas Syndicated political columnist 'Actually, no God, BIG problem, because that would mean this life is all there is and, thus, without purpose or meaning and without hope for anything beyond this life. And if there is no God the very idea of `goodness' becomes relative and subject to change. Even dictators think they are doing `good.' The bigger question is: If one can be `good' without God, why bother? Indulge yourself. Be selfish. Be promiscuous. Cheat on your spouse. Cheat on your taxes. Lie and steal. Hate and destroy your enemies. If there is no God, who is to say anything is bad ... or good? Susan Brooks Thistlethwaite Professor, Chicago Theological Seminary 'The humanists are pointing out the obvious. American public holidays are about consumption, not God. Even worse, the Christian faith has internalized this message of cultural Christmas. Christians themselves often forget what Christmas is really about. The humanists really can't do any more harm to Christians about Christmas than we've already done to ourselves.' Richard Mouw President, Fuller Theological Seminary 'We evangelical types have paraded enough of our own in-your-face stuff in public places, so why should we complain when the unbelievers do the same? Nor should we get too worked up when those same folks insist that morality is possible without a belief in God. Actually, the Bible itself teaches that such is the case. In the second chapter of his Epistle to the Romans, St. Paul says that people who do not acknowledge God's existence still have some knowledge of the morality for which God designed us, since what God's `law requires is written on their hearts, to which their own conscience also bears witness.' ' Robert Parham Executive director, Baptist Center for Ethics 'As a Christian, I must confess that the American version of Christmas is too materialistic and narcissistic. It's more about getting than giving, more about ourselves than others, more about Santa than the Savior. 'If there is a grand conspiracy with `Happy Holidays,' instead of `Merry Christmas,' it has to do with commercialization of a sacred event for the singular purpose of profit, not purging faith from the public square. I wish Christian fundamentalists felt less alienated from our culture and were more on target with moral critique.
