Anglicans like to say that we follow the Bible, informed by the first 5 Councils and first 500 years of the church. The Trullo Council was in 692 AD and is accepted by the Eastern Orthodox, but Anglicans don't. "Left-handedness of the adversary"? Is this why some folks in the middle ages thought left-handedness was a sign of the devil? I think it's worth noting that even within the first 500 years and 5 Councils, the spiritual condition and theological understanding of the church were not static. I don't thing we should view all 500 years/5 Councils with equal weight. It makes no sense to paint a bright red line in time and say, everything on one side is perfectly fine and everything starting 1 second later is not. The further in time from the Ascension and the days of the Apostles, the more errors crept progressively into people's thinking. Thus the first 100 years give us the most solid view of orthodoxy, the second hundred years less so, the third hundred years somewhat less so, and fourth hundred years still less, and so on.... in other words, a sliding scale. While the fathers of the 5th Council and the period from 401 AD- 500 AD may still inform our understanding of Scripture, they do so with less perspicacity than their predecessors. By the time we get to Trullo (in Constantinople, late 7th. Century) we can safely assume that some things are going to be considerably messed up.
