At times I think the truest image of God today is a black inner-city grandmother in the United States or a mother of the disappeared in Argentina or the women who wake up early to make tortillas in refugee camps. They all weep for their children, and in their compassionate tears arises the political action that changes the world. The mothers show us that it is the experience of touching the pain of others that is the key to change.

Trade is now clearly designed to favor the wealthiest and most powerful corporations at the expense of the rest of us. The three wealthiest people on earth now control more assets than the combined incomes of 600 million people in the world's 48 poorest countries.

We have got some mountains to move. Three billion people - half of God's children - are living on less than $2 a day.

Martin Luther King Jr. really understood the role of the churches when he said, 'The church is not meant to be the master of the state.' We don't sort of take power and grab the levers of government and impose our agenda down people's throats.

Faith can cut in so many ways. If you're penitent and not triumphal, it can move us to repentance and accountability and help us reach for something higher than ourselves. That can be a powerful thing, a thing that moves us beyond politics as usual, like Martin Luther King did. But when it's designed to certify our righteousness - that can be a dangerous thing. Then it pushes self criticism aside. There's no reflection.

The best response to bad religion is better religion, not secularism.

I believe in the separation of church and state, absolutely. But I don't believe in the separation of public life from our values, our basic values, and for many of us, our religious values.
