Pretending that the world’s religions are the same does not make our world safer. Like all forms of ignorance, it makes our world more dangerous. What we need on this furiously religious planet is a realistic view of where religious rivals clash and where they can cooperate.

Widespread criticisms of jihad in Islam and the so-called sword verses in the Quran have unearthed for fair-minded Christians difficult questions about Christianity's own traditions of holy war and 'texts of terror.' Like Hinduism's Mahabharata epic, the Bible devotes entire books to war and rumors thereof. Unlike the Quran, however, it contains hardly any rules for how to conduct a just war.

One of history's most dangerous games begins with dividing the world into the good guys and the bad guys and ends with using any means necessary to take the villains out.

Almost all religions provide opportunities for human beings to convince themselves of their own righteousness, to speak in the name of God, and even to go to war on God's behalf. This 'blasphemy of certainty' is also rife among secularists who in their case have not God but science or the proletariat on their side.

If religion is about the sacred as opposed to the profane, the spirit as opposed to matter, the Creator as opposed to the created, Confucianism plainly does not qualify. But perhaps what we are to learn from this tradition is not that Confucianism is not a religion but that not all religious people parse the sacred and the secular the way Christians do.

Like all religious people, Christians repress, remember, and retell their core stories selectively. They emphasize this episode at the expense of that episode, in keeping with their own biases and the preoccupations of their times.
