most of the population was illiterate???
Yes. Formal education was a luxury in the first century. Why do you think they needed scribes?
Are you really saying that because there were no newspapers or books or pamphlets most people were illiterate???
Not what I said but lack of print materials without a doubt does contribute to illiteracy. However my point was that lack of print venues made it difficult to distribute the gospels widely.
ancient nations invented the written word without books, newspapers and pamphlets...give them some credit.
It does not logically follow that the existence of the written word means most of the population is literate.
The apostles and early disciples were able to read and write, Jesus was reading aloud in the synagogues from a young age so I think you can safely conclude that most people could read and write in the first century.
How do you know that most of the apostles and disciples were able to read and write? Not at all clear that this is so. There is some evidence that Jesus may have been able to read and write, yes. But it does not follow that the general population could read and write just because Jesus could, or even the apostles/disciples.
