If Jesus is God, Luke 2:40-56 could (should?) be read as,
"Now the parents of God went to Jerusalem every year at the feast of the Passover. And when God was twelve years old, they went up according to custom and when the feast was ended, as they were returning, God stayed behind in Jerusalem. The parents of God did not know it, but supposing God to be in their company they went a day's journey, and they sought God among their kinsfolk and acquaintances and when they did not find God, they returned to Jerusalem, seeking God. After three days they found God in the temple, sitting among the teachers, listening to them and asking them questions and all who heard God were amazed at the understanding of God and His answers. And when they saw God they were astonished and the mother of God said to him, "God, why have you treated us so? Behold, your father and I have been looking for you anxiously." And God said to them, "How is it that you sought me? Did you not know that I must be in the house of my Father?" And they did not understand the saying which God spoke to them. And God went down with them and came to Nazareth and God was obedient to them and the mother of God kept all these things in her heart. And God increased in wisdom and in stature and in favor with God and man."
