The Star of Bethlehem has become an indispensable part of the Christmas Crib. But, we do not see the star in Gospel narrations till the time Magi arrive :
In the time of King Herod, after Jesus was born in Bethlehem of Judea, wise men from the East came to Jerusalem, asking, “Where is the child who has been born king of the Jews? For we observed his star at its rising,...... Then Herod secretly called for the wise men and learned from them the exact time when the star had appeared. ................ When they had heard the king, they set out; and there, ahead of them, went the star that they had seen at its rising, until it stopped over the place where the child was.
It is possible that the Magi had set out from their homeland(s) on seeing the star, the rising of which coincided with the Nativity. But, it is strange that there is no mention of the star at the time of Nativity in the gospels. The star could be mentioned along with the celestial song of the angels , and could work as a sign for the shepherds(Lk 2: 8-16).
My question therefore, is: According to Catholic scholars, was the Star visible over Bethlehem on the day of Nativity ?
