All religions are designed to teach us how to live, joyfully, serenely, and kindly, in the midst of suffering.

The more aggressive our ideologies become, the more aggressive our discourse whether it's in the United States, from Washington D.C., or whether it's from Tehran, or from some underground Al-Qaeda cell. The more aggressive that discourse is, the more people of moderate persuasion have to organize and speak a voice of compassion. That means to feel with the other.

Yes, all fundamentalists feel that in a secular society, God has been relegated to the margin, to the periphery and they are all in different ways seeking to drag him out of that peripheral position, back to center stage.

Now I think one of the reasons why religion developed in the way that it did over the centuries was precisely to curb this murderous bent that we have as human beings.

Religious ideas and practices take root not because they are promoted by forceful theologians, nor because they can be shown to have a sound historical or rational basis, but because they are found in practice to give the faithful a sense of sacred transcendence.

And sometimes it's the very otherness of a stranger, someone who doesn't belong to our ethnic or ideological or religious group, an otherness that can repel us initially, but which can jerk us out of our habitual selfishness, and give us intonations of that sacred otherness, which is God.

We can't say what God is, and until the modern period, Jewish, Christian, and Muslim theologians in the three God religions all knew that. They insisted that we have no idea what we meant when we said that God was good, or wise, or intelligent.
