"The one and only test of a valid religious idea, doctrinal statement, spiritual experience, or devotional practice was that it must lead directly to practical compassion. If your understanding of the divine made you kinder, more empathetic, and impelled you to express this sympathy in concrete acts of loving-kindness, this was good theology. But if your notion of God made you unkind, belligerent, cruel, or self-righteous, or if it led you to kill in God's name, it was bad theology. Compassion was the litmus test for the prophets of Israel, for the rabbis of the Talmud, for Jesus, for Paul, and for Muhammad, not to mention Confucius, Lao-tsu, the Buddha, or the sages of the Upanishads."

“One of the most characteristic new developments since the 1970s has been the rise of a type of religiosity that we usually call “fundamentalism” in most of the major world religions, including the three religions of God. A highly political spirituality, it is literal and intolerant in its vision. In the United States, which has always been prone to extremist and apocalyptic enthusiasm, Christian fundamentalism has attached itself to the New Right. Fundamentalists campaign for the abolition of legal abortion and for a hard line on moral and social decency.”

“Monotheism is essentially inimical to tribalism: it demands that a people unite in a single community.”

“Ironically, the first thing that appealed to me about Islam was its pluralism. The fact that the Qur'an praises all the great prophets of the past. That Mohammed didn't believe he had come to found a new religion to which everybody had to convert, but he was just the prophet sent to the Arabs, who hadn't had a prophet before, and left out of the divine plan. There's a story where Mohammed makes a sacred flight from Mecca to Jerusalem, to the Temple Mount. And there he is greeted by all the great prophets of the past. And he ascends to the divine throne, speaking to the prophets like Jesus and Aaron, Moses, he takes advice from Moses, and finally encounters Abraham at the threshold of the divine sphere. This story of the flight of Mohammed and the ascent to the divine throne is the paradigm, the archetype of Muslim spirituality. It reflects the ascent that every Muslim must make to God and the Sufis ...the mystical branch of Islam, the Sufi movement, insisted that when you had encountered God, you were neither a Jew, a Christian, a Muslim. You were at home equally in a synagogue, a mosque, a temple or a church, because all rightly guided religion comes from God, and a man of God, once he's glimpsed the divine, has left these man-made distinctions behind.”

“Compassion is not a popular virtue. Very often when I talk to religious people, and mention how important it is that compassion is the key, that it's the sine qua non of religion, people look kind of balked, and stubborn sometimes, as much to say, "what's the point of having religion if you can't disapprove of other people?" And sometimes we use religion just to back up these unworthy hatreds, because we're frightened too.”

“Muhammad became the archetypal example of that perfect submission to the divine, and Muslims, as we shall see, would attempt to conform to this standard in their spiritual and social lives. Muhammad was never venerated as a divine figure, but he was held to be the Perfect Man. His surrender to God had been so complete that he had transformed society and enabled the Arabs to live together in harmony. The word Islam is etymologically related to salam , and in these early years Islam did promote cohesion and concord.”

“The only way to show a true respect for God is to act morally while ignoring God’s existence.”
