I've seen other EOs criticizing the West for having paid too much attention to Augustine ever since his own lifetime. This is probably too slippery a distinction to be worth arguing over.
The first heresies did arise in the East, but no time was wasted for the Church to treat such as heresies.
I wonder what Athanasius would have made of that during his many apparent defeats.
Compare that to the way Protestants reject the Jehovah's Witnesses and similars without any need for protracted struggles or deliberations. I'm not criticizing the early theologians of course; merely being early meant they had to fight to initial outbreaks of heresy, rather than revivals of already-defeated heresies, and had to work out the precise formulations instead of having them already written. But do be accurate about what happened.
As far as St. Augustine is concerned, his works did not reach the East until the 16th century. Those dealing with the "original sin" were unknown to the Eastern Church and were rejected. But he is a venerated Saint in the East as well as in the West.
If there is one thing that all three major devisions of Christianity share in common, and that neither Luther nor Calvin questioned is the Trinity. That is about the only thing that binds all of us into one disunited ekklesia. Those sects that reject Trinity are simply not any more "Christian" then all the different flavors of Gnostics.
