Earnest : Do you think that these many groups considered themselves orthodox (i.e. representing the teachings of Christ and the apostles) or heretical?
Sea Breeze : What does that have to do with anything? Why would it matter what heretics think of themselves?
You miss my point. There was no dominant group until the fourth century and later, so the writers you are quoting from were also considered "heretics" in the second and third centuries as far as other Christian groups were concerned. The non-Jewish Logos theology did not have a monopoly at that time. Thus, for example, the Monarchians found their theology "inconsistent with monotheism". And claims of apostolic succession were so widespread they were only limited by lack of imagination.
