You are re-wiritng the history. but then Protestants make up their theology; why not history as well? It's pathetic.
It affirmed what the churches had been using all along and it wasn’t “The Church
You are wrong. St. Ignatius wrote as early as 105 AD that there is only one, Catholic Church, not many 'churches.' St. Justin martyr certainly did not speak of "churches" and neither did St. Irenaeus, or St. Clement of Alexandria, and so on. The canon as we know today was first proposed by St. Athanasius in the middle of the 4th century. It was accepted by the Church as a whole, as a standard, 30years later. That means that before 360 AD there was NO standard Christian Canon as we know it today and that many books we consider inspired today were either not listed or recognized as inspired by many churches prior to that.
Those are facts. Then there is Protestant fantasy.
There is only one church? Which one, the Eastern Orthodox, the Roman Catholic, or what?
