What a tired old talking point. Just a little research reveals that the Holy Spirit guided Born Again Christians in seeing which books were inspired and which to reject. Just one example is the quick rejection of the "Protoevangelium of James". This book written in the 2nd century was rejected before the Roman church was able to use state power to enforce it's will.
IOW, there was very little controversy concerning what was inspired and what wasn't. The only time some council was called, or a bishop made some sweeping declaration, was because pagan beliefs were growing within a given area. Also, these supposed authoritative statements only start showing up several generations after the Apostolic Era had ended. The fact there wasn't more controversy earlier is a testimony to how seriously Christians viewed Scripture.
They were late to the party by almost 100 years ... but they like to suppose they called the party ...
