And they did not understand the saying that he spoke to them. (Luke 2: 50)
Now his parents went to Jerusalem every year at the Feast of the Passover. And when Jesus was twelve years old, they went up according to custom. And when the feast was ended, as they were returning, the boy Jesus stayed behind in Jerusalem. His parents did not know it, but supposing him to be in the group they went a day's journey, but then they began to search for him among their relatives and acquaintances, and when they did not find him, they returned to Jerusalem, searching for him. After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. And all who heard him were amazed at his understanding and his answers. And when his parents saw him, they were astonished. And his mother said to him, “Son, why have you treated us so? Behold, your father and I have been searching for you in great distress.” And he said to them, “Why were you looking for me? Did you not know that I must be in my Father's house?” And they did not understand the saying that he spoke to them. And he went down with them and came to Nazareth and was submissive to them. And his mother treasured up all these things in her heart. (Luke 2: 41-51)
Jesus instructs the experts of faith of His time and they are astounded by His wisdom. In today's Gospel the events last for three days and suggest a prophetic significance. Jesus' parents, distressed and frightened after losing him, once they find him cannot understand the answer He gives them. But since they were persons of deep faith, they didn’t grumble but rather chose to love Him before understanding Him. May Mary and Joseph be models for us so as not to grumble to God when things do not go the way we wanted.
