We read in Luke 2: 43-46, the incident relating to the visit of child Jesus and his parents to the Temple and his `getting lost' at Jerusalem:
After the festival was over, while his parents were returning home, the boy Jesus stayed behind in Jerusalem, but they were unaware of it. Thinking he was in their company, they traveled on for a day. Then they began looking for him among their relatives and friends. When they did not find him, they went back to Jerusalem to look for him.
The distance they would have to cover from Jerusalem to Nazareth was 65 miles and it would take them days together to complete the journey. Some traditions say (sorry, I am not able to quote any reference) that in those days, men and women took separate routes because of which each of the parents was unable to communicate with the other, the presence of children with either of them. One is, however, unable to know why it took one day for Jesus'parents to realize that he had been left behind. My question therefore, is: who does the Catholic Church explain the time of one day that Jesus' parents took to conclude that boy Jesus had been left behind at the Temple in Jerusalem.
