I’ve posted this quote from Markus Barth, from his book The Broken Wall, before, but I think it bears repeating:
When no tensions are confronted and overcome, because insiders or outsiders of a certain class or group meet happily among themselves, then the one new thing, peace, and the one new man created by Christ, are missing; then no faith, no church, no Christ, is found or confessed. For if the attribute “Christian” can be given sense from Eph. 2, then it means reconciled and reconciling, triumphant over walls and removing the debris, showing solidarity with the “enemy” and promoting not one’s own peace of mind but “our peace.” . . . When this peace is deprived of its social, national, or economic dimensions, when it is distorted or emasculated so much that only “peace of mind” enjoyed by saintly individuals is left—then Jesus Christ is being flatly denied. To propose, in the name of Christianity, neutrality or unconcern on questions of international, racial, or economic peace—this amounts to using Christ’s name in vain.
This is, I think, the litmus test for all of our schemes and programs and ideas to grow the church: if we’re just creating conditions in which “insiders or outsiders of a certain class or group meet happily among themselves,” we may have great success in growing an organization—done skillfully, that sort of approach is certainly the path of least resistance in doing so—but what we’re producing won’t be the church.Christian unity costs us something. It costs us our egos, our comfort zones, and our ease. It calls us not to avoid those with whom we disagree, or with whom we have issues, or with whom we’re in conflict, but rather to confront them head-on—and to do so not with anger, or self-assertion, but with love and grace. This is not to say we must do so with approval; there are times when rebuke is necessary, and refusing to speak the hard truths is a violation of unity just as much as refusing to repent of our own sin and ask forgiveness. It is to say, however, that we cannot hang back from the work of reconciliation, and we cannot let mere disagreement become grounds for disunity. We may be rejected by others—but we cannot in good conscience be the ones to do the rejecting; and though there are times when God calls us to correct one another, even correction must be offered with open arms.
