<<with the possible exception of #7 you have perfectly described Roman Catholicism. The authority of scripture is a classic example of group think.>>
Excellent point Cofty. I am not prepared to argue against it. However it seems to me that there are significant differences among Christian groups that go beyond simply degree of manifestation of the cult characteristics listed.
For example, take the first one:
1. Claim Exclusive Divine Approbation
All Cult groups are elitist, claiming special exalted status for themselves, their leadership and members. Cults are organizational exclusivists. One is excluded from possible relationship with God if one is not associated with the group. The group alone represents true Christianity and all other groups are demonic or inspired by satan. The group is the exclusive community of the saved and those who leave the group, leave God.
Unlike cults, most Christian churches do not claim such status. Most Christian groups clearly tend not to be organizational exclusivists, but relational exclusivists; one must have a relationship with Jesus Christ to be a Christian. Which church you belong to or visit or celebrate communion at, is essentially inconsequential.
