I think there are two basic religious dispositions in the world: fundamentalists and latitudinarians. And this seems to be true not only for Christianity, but for Islam and (to a lesser extent) Judaism as well.

Fundamentalists, of course, are those who identify so completely with a given religious ideology that they are deeply threatened by anyone who questions it. Their fixed attitude is "my way or no way;" they are "God's People," and if we don't accept their ideology, we are, ipso facto, enemies of God, and must be either converted or eliminated. Fundamentalists are therefore responsible for ALL the religious violence that has afflicted the world for centuries, for if our own enemy is therefore the enemy of God, then no compromise is possible.

Latitudinarians are those who, while they may hold religious beliefs, are perfectly comfortable around those who have different beliefs, because they are well aware that religious ideologies are just maps of the same territory, and that "territory"--the nature of God or the Sacred--cannot be known directly or contained by any ideology. They understand that faith is not belief, but beliefs are simply culturally determined ways of understanding or expressing faith. So what is faith? Trust. And genuine trust in God (or Allah, or JHVH, or the Sacred--whatever name works for us best) is intuitive, not based on ideology. Faith (that is, trust in the Sacred) is entirely compatible with reason, scientific investigation, and common sense. It is not threatened by the opinions or beliefs of others.
