The following is excerpted from the "Executive Summary" of An Evangelical Manifesto (www.evangelicalmanifesto.com). I encourage you to read the whole document, if you can. After first staking out a theological understanding of the term "evangelical" ( a definition I found sound and unremarkable), the document goes on to say:
"Second, we wish to reposition ourselves in public life. To be Evangelical is to be faithful to the freedom, justice, peace, and well-being that are at the heart of the good news of Jesus. Fundamentalism was world-denying and politically disengaged at its outset, but Evangelicals have made a distinguished contribution to politics—attested by causes such the abolition of slavery and woman’s suffrage, and by names such as John Jay, John Witherspoon, Frances Willard, and Sojourner Truth in America and William Wilberforce and Lord Shaftesbury in England. Today, however, enormous confusion surrounds Evangelicals in public life and we wish to clarify our stand through the following assertions:
"First, we repudiate two equal and opposite errors into which many Christians have fallen. One error is to privatize faith, applying it to the personal and spiritual realm only. Such dualism falsely divorces the spiritual from the secular and causes faith to lose its integrity. The other error, made by both the religious left and the religious right, is to politicize faith, using faith to express essentially political points that have lost touch with biblical truth. That way faith loses its independence, Christians become the “useful idiots” for one political party or another, and the Christian faith becomes an ideology. Christian beliefs become the weapons of political factions.
Called to an allegiance higher than party, ideology, economic system, and nationality, we Evangelicals see it our duty to engage with politics, but our equal duty never to be completely equated with any party, partisan ideology, or nationality. The politicization of faith is never a sign of strength but of weakness.
"Second, we repudiate the two extremes that define the present culture wars in the United States. On one side, we repudiate the partisans of a sacred public square, those who would continue to give one religion a preferred place in public life. In a diverse society, it will always be unjust and unworkable to privilege one religion. We are committed to religious liberty for people of all faiths. We are firmly opposed to theocracy. And we have no desire to coerce anyone or to impose beliefs and behavior on anyone. We believe in persuasion.
On the other side, we repudiate the partisans of a naked public square, those who would make all religious expression inviolably private and keep the public square inviolably secular. This position is even less just and workable because it excludes the overwhelming majority of citizens, who are still profoundly religious. Nothing is more illiberal than to invite people into the public square but insist that they be stripped of the faith that makes them who they are.
"We are committed to a civil public square – a vision of public life in which citizens of all faiths are free to enter and engage the public square on the basis of their faith, but within a framework of what is agreed to be just and free for other faiths as well. Every right we assert for ourselves as Christians is a right we defend for all others. "
