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.
That was certainly true but just because a local bishop deemed something "inspired" didn't make the writing inspired. It was the Church that sorted out what was inspired from what wasn't. That's all they did.
