Exactly!!
In fact, let's even go farther. There were many apocryphal books floating around. And many copies of Scripture that were tampered with to reflect theological positions.
So in order to trust a copy of the Scripture you were looking at, you had to *trust the person who provided it to you*. That they were not in league with heretics and got bad copies of the thing. That they would read it to you correctly.
Of course the sola scriptura position is completely untenable in this situation. Even the person who adopts it today has to perforce trust a legion of folks from his ministers/publishers/translators on.
And they must also agree that God has CRUELLY DENIED this opportunity to billions of Christians throughout history, that God effectively said to billions, "You can read the Bible and be Saved OR you can have food, clothing and shelter, your choice."
I have a lifelong love of history and my favorite period is medieval Europe and the reality is that during the Middle Ages all of Europe was under feudalism and well over 90% of the population was impoverished and this didn't begin to change until the social upheaval brought on by the Black Death in the mid-14th century. Nearly every person had to work land that they didn't own in order to earn enough to eat and live in a hut that they also didn't own. Depending on the crops, starvation was a very real concern on a daily basis. It was IMPOSSIBLE for these people to own a Bible, because even if that was their choice, they would starve before they saved the money.
