John Piper’s August 2002 paper on “Tolerance, Truth-Telling, Violence, and Law: Principles for How Christians Should Relate to Those of Other Faiths” did not get a great deal of attention at the time (so far as I recall), but it remains just as relevant now as it did in the months following 9/11.
It was originally prompted by the question of how Christians and Muslims should relate to each other. “This question,” Piper explains, “is part of the larger issue of how Christians are called to live in a pluralistic world. More specifically, how shall we as American Christians think and act with regard to freedom of religion in a pluralistic context defined by the ideals of representative democracy? In particular, how shall we bear witness to the supremacy of Christ in a world where powerful cultures and religions do not share the love of freedom or the ideals of democracy?”
I’ve reproduced the principles below.
1. Whether approved or disapproved by others, we should thankfully and joyfully hold firmly to the true biblical understanding of God and the way of salvation he has provided and the life of love and purity and justice Christ has modeled and taught.
2. Both in the church and the world we should make clear and explicit the whole counsel of God revealed in his inspired word, the Bible—both the parts that non-Christians approve and the parts that they don’t. We should not conceal aspects of our faith in order to avoid criticism or disapproval.
3. It is loving to point out the error and harm of Christ-denying faiths. The harm consists not only in some temporal effects, but especially in the eternal pain caused by refusing the truth of Christ. This warning should be given with earnestness and longing for the good of those who are in danger of the consequences of not trusting Christ.
4. We Christians should acknowledge our sin and desperate need of salvation by a crucified and risen Savior, so that we do not posture ourselves as worthy of salvation as if we had superior intellect or wisdom or goodness. We are beggars who have, by grace, found the life-giving bread of truth, forgiveness, and joy. We desire to offer it to all, so that they join us in admiring and enjoying the greatness of Christ forever.
5. We should present Christ not as the triumph of an argument among religions but as the most trustworthy, beautiful, important, and precious person in history, and as our desperately needed and loved substitute in two senses: (1) He absorbed, by his suffering and death, the wrath of God in our place; and (2) he became our righteousness before the all-holy God by living a sinless life which was imputed as righteousness to us when we believed on Jesus.
6. We should make clear that Christian faith, which unites us to Christ and all his saving benefits, is a childlike, self-despairing trust in the worth and work of Christ, not a meritorious work of our own. Our call for others to be Christians is not a call to work for God or to earn his approval by doing deeds of righteousness or love. We are calling for people to renounce all self-reliance and rely entirely on the saving life and death of Jesus Christ.
7. We believe it is a just and loving thing to publicly point out the errors of other faiths…
