Here's his contemporary Justin Martyr:
"And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things."
The NT was originally not a bound book published for personal home instruction. It was a collection of documents circulated and read liturgically.
I do not dispute that. I entered the conversation after the oft repeated wranglings about Peter when roamer tossed that softball about a "clear word." That rekindled the memory of my own spiritual journey when I had to grapple with why I believed what I thought I believed. And among the first, the question of authority had to be dealt with.
