Religions are divisive and quarrelsome. They are a form of one-upmanship because they depend upon separating the “saved” from the “damned,” the true believers from the heretics, the in-group from the out-group. Even religious liberals play the game of “we’re-moretolerant-than-you.” Furthermore, as systems of doctrine, symbolism, and behavior, religions harden into institutions that must command loyalty, be defended and kept “pure,” and—because all belief is fervent hope, and thus a cover-up for doubt and uncertainty religions must make converts. The more people who agree with us, the less nagging insecurity about our position. In the end one is committed to being a Christian or a Buddhist come what may in the form of new knowledge.
New and indigestible ideas have to be wangled into the religious tradition, however inconsistent with its original doctrines, so that the believer can still take his stand and assert, “I am first and foremost a follower of Christ/Mohammed/Buddha, or whomever.” Irrevocable commitment to any religion is not only intellectual suicide; it is positive unfaith because it closes the mind to any new vision of the world. Faith is, above all, open-ness—an act of trust in the unknown.
