We know where Jesus is from, and he cannot be the Christ. [For] when the Christ comes, no one will know where he is from. The Christ, or rather the Messiah, as the Christ figure was popularly known among the people of Jesus’ time, was an enigmatic figure. The prophets had foretold of his coming, and the people in almost every generation awaited his coming with eager expectation because the Christ is a bringer of good things. The Christ remained an enigmatic figure because although many had come out and claimed to be the one, none had lived to the expectations of the people and were consequently rejected. It is this very situation in which Jesus found himself. Despite situating his mission/ministry in the fulfillment of the prophecies of old (cf. Luke 4:18-19) and working mighty signs before their very eyes, the people were slow to accept him as the Christ Messiah for reasons that vary depending on where one is standing. In the Gospel reading for today, we see the crowds pointing to the fact that Jesus was one of their own and as such could not be the Christ. The Christ, they reasoned, would have to be and remain a mysterious (enigmatic) figure. 
The crowds who rejected Jesus were raising an issue that is not new to us: we don’t like the simple/easy/cheap/familiar. We are readily filled with awe at the complex and mysterious while remaining unmoved by the simple and that which is familiar to us. And we tend to apply this to our relationship with God as well. A God who is easy to access, one who is simple and easy to get along with loses our respect, so to speak. A God who assumed our nature and tends to get involved in our mundane affairs becomes suspect. It was not only the knowledge of where Jesus came from that made the people to reject him. It was also the fact that Jesus was just Jesus, a fellow human being with a name such as theirs. To the crowds, Jesus was merely a fellow human being who was subject to cosmic laws just as they were. They rejected Jesus as the Christ because he was just like them. How could he help them scale the heights while he himself was just as ordinary?
The Christ comes to us as one of our own to make it easy for us to attain salvation. God doesn’t want us to sweat or perform nearly impossible tasks in order to attain our salvation. Jesus comes to us as one of us to show us that salvation lies in living our lives without pretense. It is not in living extraordinary lives that we attain salvation but rather in remaining simple, easy, familiar sons and daughters, mothers and fathers. For Jesus has not come to show us how to become extraordinary or complex beings but rather how to become loving and kind children of the Father.
