The episode of the young Jesus discussing theology at the temple is actually mentioned only in Luke. I don't remember other episodes in which he explicitly does that (so if someone could point them out, I'd appreciate it).Maaaaaaaarten said:The gospels.
And as for this one:
I'd feel it better to stick with the historical sources. If Jesus was illiterate and could not debate scripture or whatever, how do you explain that the account we have of his live all describe doing exactly that?
So yes, it may be remarkable for Jesus to have learned how to read, considering his background. But if all our historical sources portray him as discussing scripture as a fundamental part of his public ministry, then what's the more likely conclusion? That all of that stuff is just made up, or that he learned to read, because he wanted to read the scriptures?
Also I'd be hesitant to call the gospels "historical sources".
