Hey DATA-DOG,
Having read your opening post, I see that you are burdened with some mistaken impressions.
#1) You have assumed that Joseph, Mary and Jesus went back to Nazareth directly after they had completed their business at the Temple (done everything the Law required). You assume that Luke 2:39 supports that conclusion.
#2) You have assumed that the "house" in which the Family lived when the Magi found them was in the town of Nazareth.
In regards to #1: You are failing to take into account that Luke leaves out some of the story that Matthew includes, just as Matthew leaves out some of the story that Luke includes. The verse you reference at Luke 2:39 doesn't represent a full picture of where the Family went after they completed their business at the Temple and eventually wound up back in Nazareth. Yes, in that verse Luke left out the part in which Matthew described their sojourn into Egypt. So you are quite mistaken in thinking that the Family returned to Nazareth immediately after they finished their business at the Temple. The fact is they remained in Bethlehem for a while. And they were still in Bethlehem when the Magi came to Jerusalem inquiring about the one born that was destined to become the king of the Jews. After the Magi had left, Joseph was told to flee into Egypt because Herod was going to kill Jesus. Joseph took his family and went to Egypt, and then after Herod had died he was told to be on his way back to the land of Israel. Joseph did as he was instructed, and he went to the town of Nazareth - the same town where he and Mary lived before going to Bethlehem in order to be registered. So these are the facts with regards to their line of travel: They first lived in Nazareth. Then they went to Bethlehem to be registered. Mary gave birth to Jesus while there, in a stable, and they continued to live in Bethlehem for a time. While living in Bethlehem the Magi came. After the Magi left, they themselves left Bethlehem and went to Egypt. After Herod died they returned to Nazareth.
In regards to #2: The "house" in which the Family lived when the Magi found them was in Bethlehem, not Nazareth. Matthew 2:8 says that Herod sent the Magi to Bethlehem, not to Nazareth. The Magi didn't see the "star" sitting above a house in Nazareth. No, it was sitting above a house in Bethlehem.
According to your way of thinking: Joseph and Mary went from Nazareth to Bethlehem, then back to Nazareth. Then, after seeing the Magi, they left Nazareth again and went to Egypt, and then back to Nazareth again after Herod died.
But the correct way of thinking is like this: Joseph and Mary went from Nazareth to Bethlehem. Then, after seeing the Magi, they left Bethlehem and went to Egypt, and after Herod died they went back to their point of origin, namely Nazareth.
It's obvious that you are in need of getting important details straight in your mind, DATA-DOG.
