Wholeheartily agree with your post.
I have always, and I have to express ALWAYS, had an issue with the constant criticism of the early church. Even when I was a kid and we use to study the "All Scripture is Inspired" book, I would read the passages about the early "church" and ask "What "church" are we talking about?" If the Roman Catholic "Church" was the only "organized" church at the time, then aren't we talking about them? To criticize the early church as "apostate" and then in the same breath state that God blessed the process of the canonization of holy writings aka the Bible by means of that same early church is tantamount to saying that Charles Manson was a good parent!
The thing that eventually opened my eyes to this whole issue was the study of Marcion, the son of the bishop of Sinope. The church excommunicated Marcion because of his heretical views and by the end of the second century his impact of the church was notable. It was a "reaction" of the church to his selected canon that our current canon exists. Try to make sense of that?
