KIM LAWTON, guest anchor: Now, the legacy of a veteran activist for peace. The growing faith-based mobilization against the war in Iraq is reminiscent of religious action against the Vietnam War. One key leader in that effort was the late Reverend William Sloane Coffin (1924-2006). As chaplain of Yale University in the '60s and '70s, Coffin became one of the best known -- and most controversial -- figures not only against the war, but also in the civil rights movement and the campaign for a freeze on nuclear weapons. Throughout his life, Coffin preached that social justice was central to Christianity. He died last year at the age of 81. Bob Abernethy interviewed Coffin in 2004.

BOB ABERNETHY: Toward the end of his life, in the summer of 2004, I interviewed Coffin for this program.

Coffin had retired to the little town of Strafford, Vermont, where he lived on the village green with his wife, Randy, and their terrier, Rosie. Coffin was 80 years old then. Two strokes had slurred his speech. He couldn't walk much, and had had to give up playing the piano, of which he had been a master. But his commitments and beliefs were as strong as ever.

The Reverend WILLIAM SLOANE COFFIN: I thank God for all the young men and women here who are going to refuse registration.

ABERNETHY: Today, Coffin has retired to the little town of Strafford, Vermont, where he lives on the village green with his wife, Randy, and their terrier, Rosie. Coffin is 80 years old now. Two strokes have slurred his speech. He cannot walk much and has had to give up playing the piano, of which he was a master. But his commitments and beliefs are as strong as ever.

The Rev. COFFIN: What this country needs, what I think God wants us to do, is not practice piecemeal charity but engage in wholesale justice. Justice is at the heart of religious faith. When we see Christ empowering the poor, scorning the powerful, healing the world's hurts, we are seeing transparently the power of God at work.

God is not too hard to believe in. God is too good to believe in, we being such strangers to such goodness. The love of God is to me absolutely overwhelming.

It's clear to me, two things: that almost every square inch of the Earth's surface is soaked with the tears and blood of the innocent, and it's not God's doing. It's our doing. That's human malpractice. Don't chalk it up to God. Every time people say, when they see the innocent suffering, every time they lift their eyes to heaven and say, "God, how could you let this happen?" it's well to remember that exactly at that moment God is asking exactly the same question of us: "How could you let this happen?" So you have to take responsibility.

If you back off from every little controversy in your life you're not alive, and what's more, you're boring.

ABERNETHY: I asked Coffin to think back on the civil rights and other protest movements he helped lead.

The Rev. COFFIN: I think the greatest pleasure was being with black civil rights leaders and followers, because they were so alive. You can be more alive in pain than in complacency.

The antiwar movement split the nation in a more acute, painful way. I think, in retrospect, just about everybody agrees it was a terrible, terribly misconceived war.

ABERNETHY: Coffin became the leader of the U.S. campaign against nuclear weapons.

The Rev. COFFIN: Only God has the right to destroy all life on the planet. All we have is the power. We haven't the authority. Therefore to make, to threaten to use nuclear weapons must be an abomination in the sight of God.
