Orthodox Study Bible

I was at a retreat once which was led by Archbishop Demetrios, a noted scholar and well respected in Biblical Studies... especially the Old Testament. He made it clear that although the disciples were not all employed in scholarly professions, they were well versed in the OT enough to recognize who Jesus was, enough so to leave every thing and one behind. To say they were unlearned would imply they were irresponsible or careless. They may have not learned Economics but they definitely knew Judaism.
