I don't know this.... Not that I know a lot about church history - just a little.I thought the western Church worked independently of the eastern churches.
That the canon was a product of the western Church and carried their doctrinal biases in translation.

I don't believe there started to be problems between the East and West until about 800 or so until the final schism in 1,000AD.
If you know differently, I sure would like to see some writing on it.
I don't think there is any.
As to doctrinal bias....yes, this I know about - but it was in general.
Like, for instance, some say that Matthew 28:19 was added in to support the Trinity.
But I don't believe this because it's in alignment with the rest of the NT.
There's a verse that is definetly added,,,but I can't think of it right now.
Maybe the one about how Peter would die....
John 21:19
But I don't put this verse forth as fact ---
I'd have to look it up to be sure.
