This is what I can find on them.
It seems to be a loose confederation of Christians started in the 1970’s who follow a man called Terry Virgo (terryvirgo.org/Publisher/Article.aspx?ID=269924). They seem to believe that the early Church was a set of individual churches and seem themselves the same way “number of local churches, each with its own identity, membership and elders, working together on a mission.” Of Paul they say “His original home-base church in Antioch came into existence, not through his ministry but spontaneously, through the witness of scattered believers, which he subsequently joined.” As Terry Virgo claims to be a Bible teacher, although from his writings I personally would doubt many aspects of this claim – not least his vast gaps of basic understanding of the Bible. He has subsequently retired from leadership, not handed the reins over to anyone and simply left the churches to go their own individual ways. Funnily enough he sees noting wrong in abandoning his followers.
They don’t acknowledge the Catholic Church and do not believe that Catholics are Christians (terryvirgo.org/Articles/230819/Terry_Virgo/Resources/Articles/Series/Interview_with_Mark_Driscoll.aspx). I know it is an interview but it is backed up by other articles on the website. Some of his associates are err less than Christian in the preaching e.g. Mark Driscoll.
One of their leaders also makes the following statement without backing it up with any evidence, it just seems that he believes more in himself than in any evidence of facts. For example: “Historically the early Reformers, who wrote their commentaries on the Scriptures, were correctly hostile to the Roman Catholic doctrine of apostolic succession with the concept of infallible authority usually associated with that claim.”
Sorry this is all I am able to offer right now as I found the site depressing and very sad. I think that you might get more helpful answers from some of our Evangelical CAF members who understand the Evangelical movements better.
Upon reflection, I suggest that you ask the MODs to move this into other religions as it may get seen by more Evangelicals.
Just an initial offering.
