There is a famous oil painting called "Christ Teaching In The Temple." The painting gets it wrong. It comes from an era when religious people were still uneasy with the notion that Jesus was like the rest of us. In this picture he is standing in the midst of the elders looking very wise, obviously delivering a lecture. He is talking and pointing and they are listening. He had, no doubt, appeared to instruct them in the law, as if he knew what they didn't. But that's not what the text says. They found him, says Luke, "listening to (the teachers) and asking them questions." He was not the authority; he was the student. He was there to listen and learn. Now it is true that the religious leaders were impressed by how much he knew, and by how he answered their questions. But there is nothing in this text which indicates he was a precocious know it all.
