The toddler Jesus
Sir: Glad tidings! Miles Kington has taken up New Testament studies (16 December). But he is way off-target in suggesting that Mary’s Boy Child would have made grown-up remarks at the age of six months. Luke’s Gospel (2:46,52) makes it quite clear that Jesus was a normal child who “grew both in body and wisdom” and asked questions rather than giving answers.
The passage in question recounts the story of Jesus going to the temple as a young boy/man and simultaneously learning and debating Jewish theology in an extraordinarily gifted manner. This is weird, because where is that skill coming from? The fact he is God? Then why does he need to learn anything at all?
That is a reason that a baby Jesus is absurd. What was God thinking as he waved his little hands and soiled himself?
