I'm not sure I would buy into that. The Church made a clear point of separating what was inspired from what was not. When putting together the scripture the Church had a set criteria. They did not consider everything inspired; certainly the Orthodox even in those days wouldn't have considered Augustine's writings to be inspired.
That's not how the early Church operated. Different churches had different sets of scrolls, depending on what the local bishop(s) deemed "inspired." That's why you have such variations in what different churches contained. Which was one of the reasons the Church hierarchs decided to "standardize" what was read.
The ancient Church was based on +Ignatius's formula: the catholic church is where the bishop is (105 AD). Those scrolls that were physically in a church that were read at liturgy were considered scripture. This the oldest complete Bibles from the early 4th century contain books that are no longer considered Christian scripture.
