I am not sure what is the point of your reply, unless you misread/misinterpreted my statement. None of those you mention professed what the Church defined dogmatically as orthodox faith. As far as I know, outside the five patriarchates, no other Church existed.
The point is that there have been heresies since the beginning. And I would wager that those who were caught up in those heresies were utterly convinced that they were practicing the orthodox Faith and that the Church had gone off the rails.
