seeing that the Catholic church was the ONLY source for Christian information to be spread throughout the world, it was, of course, the reason that so many people became educated in what Christianity really was. Since the written word was not, until the 16th century, a very effective means of spreading anything. The people attended Mass, heard the entire bible preached over a three year period, experienced pictures, statues, decorated stained glass windows, and were members of the only Christian family in the world.....That's how the word of God was spread.....not by a mega-preacher on TV.
“heard the entire bible preached over a three year period”
No, they did not.
Pre-Vatican II, only about 1% of the Old Testament was covered, and about 16% of the New Testament.
The current one, read on Sundays and major feast days, covers about 40% of the NT and 4% of the Old.
