"A political movement by nature draws lines, makes distinctions, pronounces judgment; in contrast, Jesus' love cuts across lines, transcends distinctions, and dispenses grace. Regardless of the merits of a given issue - whether a pro-life lobby out of the Right or a peace-and-justice lobby out of the Left - political movements risk pulling onto themselves the mantle of power that smothers love. From Jesus I learn that, whatever activism I get involved in, it must not drive out love and humility, or otherwise I betray the kingdom of heaven," - Philip Yancey, "The Jesus I Never Knew."
This is obviously related to my account of non-fundamentalist Christianity in this essay, "Why Not Seeing Is Believing." The political dimension of this kind of moderate faith - limited, morally neutral government - is explored in the final chapter of "The Conservative Soul."
