You will not get any credibility to your movement by linking it with the Paulicans which were a splinter group which by all accounts was heretical. If you want to establish the antiquity and orthodoxy of MAD you have to show that the Greek Fathers believed it. This means starting with Ignatius in the First Century and going on as far as John Chrysostom but avoiding the polluted teachings generated by Augustine. The Paulicans were not the first Paul only group. The Marcionites were Paul only and had a canon of Paul only books. They were considered heretical and their Bible an aberration. Don't make claims to antiquity you cannot substantiate.
They only claim made is that they appeared to have held to some views similar to our own.
And this is said, only as a passing thought on what they had had to deal with from their enemies, as that also shares some things in common with our own experience from others.
You trace your tradition back through the ECF. That's understandable. That's what people do when they have questions.
Doesn't mean it is sound, or unsound; as it has its merits.
I tried all that; in an attempt to understand my Bible. Learned a thing or two along the way...
Then I sat down and seriously asked myself "wait a minute; why do I have a Bible if I need all those books!"
Do I expect you to understand this if yours has been the more traditional approach? No; that's on you - "Let every man be fully persuaded in his own mind" Rom. 14:23.
But this difference is one that your side of the fence always has issue with.
In fact, those on our side of the fence who are ever quoting the labors of others also often have problems with us.
There comes a time when one must role up one's own sleeves on these issues and get - in - that - Book.
Even then, far too many come at it with all those books as their guide to the Book.
That's just backwards to many of us.
