Oh come on, Professor Scholar Man. Can you say "amanuensis"? I didn't think so.
Classic liberals. Sarah Palin and Peter are both God-fearing followers of Jesus, both fishermen, so they must both be illiterate. No doubt many fishermen of the time were illiterate, but a man was not automatically illiterate just because he had been a fisherman. He could, as you said have narrated his words to a scribe, or he could have learned to write while following Jesus or even before then. In a year, or three years, of following the son of God, he would have had both the time and the motivation to learn to read and write, particularly if Jesus had inside knowledge that reading and writing would become relevant later.
So very true...assuming Peter really WAS illiterate. He and his father seem to have OWNED the shipS and equipment, rather than being "simple fishermen", as in one who just cast nets.
Hard to run a comparatively expensive and complex business successfully without some acquaintance with "letters and numbers".
Matthew was a "publican", meaning a freelance tax collector & functionary, and so he also was not poor, and also probably not, out of necessity, illiterate.
Also, if one carefully looks at the Bible, Jesus's family, all the way back to Abraham, was NOT "poor and illiterate", as the poor of the times understood poor. Not all of the Apostles, and certainly a large number of (especially of the post-Resurrection) disciples, were decidedly far from poor and illiterate, also.
It is much easier to play to stereotypes and popular fancy, while stoking one's "superior knowlege" by writing such learned drivel as Ehrman and his ilk so love to do.
