A recent survey by the Barna Group indicates, more than anything else, that American Christians as a whole have wide-ranging beliefs when it comes to theology. These varieties of belief cover some of the most important doctrines of the faith including Jesus Christ, the Holy Spirit, and sin.
It is amazing to me that self-described Christians can differ so much in beliefs when we have a source to look to: the bible. Keep in mind that I'm not talking about secondary issues such as baptism, the Lord's Supper, or eschatology. This Barna survey deals with core issues of the faith.
