To what purpose, exactly?

As the "debate" at Saddleback between Presidential candidates McCain and Obama approaches Time puts Rick Warren on the cover with a story entitled "The Global Ambition of Rick Warren". Is he "the U.S.'s most influential...churchman" or is Time just promoting its candidate for that role? An excerpt:

If Warren is not quite today's Graham, who presided as "America's pastor" back when the U.S. affected a kind of Protestant civil religion, he is unquestionably the U.S.'s most influential and highest-profile churchman. He is a natural leader, a pathological schmoozer, insatiably curious and often the smartest person in the room. Like Graham, he projects an authenticity that has helped him forge an exquisite set of political connections in the White House, on both sides of the legislative aisle and abroad. And he is both leading and riding the newest wave of change in the Evangelical community: an expansion beyond social conservatism to causes such as battling poverty, opposing torture and combating global warming. The movement has loosened the hold of religious-right leaders on ordinary Evangelicals and created an opportunity for Warren, who has lent his prominent voice to many of the new concerns.

A shift away from "sin issues" like abortion and gay marriage is reflected in Warren's approach to his coming sit-downs with the candidates. He says he is more interested in questions that he feels are "uniting," such as "poverty, HIV/AIDS, climate change and human rights," and still more in civics-class topics like the candidates' understanding of the role of the Constitution. There will be no "Christian religion test," Warren insists. "I want what's good for everybody, not just what's good for me. Who's the best for the nation right now?"

If Warren were content to be merely the most influential religious figure on the American political scene, that would be significant enough. He isn't. .... [more]
