I would like to begin to give you my evidence on this debate. I hope the responses you can give are well thought out, honest, and backed by credible sources, as I hope you can see by my effort.
I want to start off by setting the landscape of what it was like in 1st century Jerusalem. The populous was almost all Jewish, and Jews who followed strict Jewish discipline and Jewish culture.
Religious wise, the teaching was done primarily through the Rabbi, who would recite the Old Testament to those who listened, largely because there were no books in the general population and virtually the entire population did not know how to read or write.
I am keeping this short because I do not like long posts that take me forever to read. If you desire further evaluation, feel free to instigate an internet search, or read some of the references provided.
Facts about 1st Century Jerusalem
1. Jerusalem was primarily Jewish in the 1st half of the 1st century 
2. The population of Jerusalem was 97% illiterate.
"Thus, it is no exaggeration to say that the total literacy rate in the Land of Israel at that time (of Jews only, of course), was probably less than 3%." 
3. Education was transmitted orally 
"Greco-Roman higher education, especially rhetoric and philosophical teaching, took place orally, without the assistance of texts of the necessity to fit arguments in writing. Loveday Alexander has shown that the rabbis did not stand alone in their "skepticism for the written word", but can be seen as representatives of a general opposition to the usage of the written word in certain contexts within Graeco-Roman society at large." Alexander refers to Galen (2nd. c. C.E.), who wrote:
"There may well be truth in saying current among most craftsmen, that reading out of a book is not the same thing as, or even comparable to, learning from the living voice" (Hezser, 2001. p. 99).
