Nope...They trace their lineage all the way back to Jesus Christ...They worship the same God the rest of us worship...
In my view, they are a little off in their understanding of scripture but hey, nothing like your religion...
You ought to stop in sometime and worship with them...
A person who never heard the Gospel before and picks up a Bible and puts their faith in Jesus for salvation by grace through faith, can only trace his *lineage* back by years, and yet is as surely a member of the body of Christ as someone who is a true believer in an old denomination.
This business of appealing to lineage and old established denominations sounds way to much like appealing to pedigree as if people are dogs and someone is trying to establish credibility or something.
Since it’s not the church that saves, denominational affiliation is MEANINGLESS. A person would be unwise to risk trying to worship in an organization which doesn’t preach the Gospel found in the NT, but that still would not mean he is unsaved.
