Thoughts on Luke 2:41-45...
Dr. Luke's reference to Mary and Joseph's attendance at the Passover festival throws a light upon their habits. The Law required that the men appear before God three times in the year.
Mary didn't lack female companions who were taking advantage of the festival period to accompany their husbands and older sons to Jerusalem.
☆ Attendance's regularity's emphasized by Dr. Luke; an example for parents today. ☆
When the boy Jesus was 12, his parents followed the rule laid down that the sons must be trained in religious duties and must take part in the festivals with their elders.
The trip to Jerusalem upon the festivals' occasion was in itself a festival. The people of the remote parts of Palestine formed caravans for traveling together. At times the older members would chant. As they neared the city, and the festival spirit seized them, they'd wave flowers and tree branches in unison' with their song.
In this case, Jesus had participated in the festival week. But when the festival closed and the pilgrims went home, Jesus stayed behind without his parent's knowledge. They thought him to be with some of their caravan and spent a day in inquiring for Him in the caravan.
But when there was no sign of Jesus, Mary was filled with fearful feelings. They rushed back to the capital city and searched it for three days.
