Faith-confidence in what we hope for (Hebrews 11)
It still does not mean that Jesus could not read or write. I can go further, but the first three translations I read on this say:The Greek (original) text reads" Πῶς οὗτος γράμματα οἶδε, μὴ μεμαθηκώς?"
meaning literally: "How does he know the letters, since he hasn't learned them?"
In any case, I wrote this because of Jesus' answer in bold.
New International Version
The Jews there were amazed and asked, “How did this man get such learning without having been taught?”
New Living Translation
The people were surprised when they heard him. “How does he know so much when he hasn’t been trained?” they asked.
English Standard Version
The Jews therefore marveled, saying, “How is it that this man has learning, when he has never studied?”
(Nothing about being illiterate, plus we know he read from the scroll in the synagogue.) Paul had great learning but didn't mean much insofar as the resurrected Jesus was concerned. So Paul changed his viewpoint.
