And it came to pass that there went out a decree from Caesar Augustus, that all the world should be taxed.
 --Bible, Luke 2:1

(122:7.1) In the month of March, 8 B.C. (the month Joseph and Mary were married), Caesar Augustus decreed that all inhabitants of the Roman Empire should be numbered, that a census should be made which could be used for effecting better taxation.

And suddenly there was with the angel a multitude of the heavenly host praising God and saying, Glory to God in the highest, and on earth peace, good will toward men.  And it came to pass, as the angels were gone away from them into heaven, the shepherds said one to another, Let us now go even unto Bethlehem, and see this thing which is come to pass, which the Lord hath made known unto us.
 --Bible, Luke 2:9-15

(122:8.5) At the noontide birth of Jesus the seraphim of Urantia, assembled under their directors, did sing anthems of glory over the Bethlehem manger, but these utterances of praise were not heard by human ears. No shepherds nor any other mortal creatures came to pay homage to the babe of Bethlehem until the day of the arrival of certain priests from Ur, who were sent down from Jerusalem by Zacharias.

(122:8.1) All that night Mary was restless so that neither of them slept much. By the break of day the pangs of childbirth were well in evidence, and at noon, August 21, 7 B.C., with the help and kind ministrations of women fellow travelers, Mary was delivered of a male child. Jesus of Nazareth was born into the world, was wrapped in the clothes which Mary had brought along for such a possible contingency, and laid in a near-by manger.

    After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem  and asked, “Where is the one who has been born king of the Jews? We saw his star when it rose and have come to worship him.”
    When King Herod heard this he was disturbed, and all Jerusalem with him. 4 When he had called together all the people’s chief priests and teachers of the law, he asked them where the Messiah was to be born. 5 “In Bethlehem in Judea,” they replied, “for this is what the prophet has written:
“‘But you, Bethlehem, in the land of Judah,
    are by no means least among the rulers of Judah;
for out of you will come a ruler
    who will shepherd my people Israel.’” 
    Then Herod called the Magi secretly and found out from them the exact time the star had appeared. He sent them to Bethlehem and said, “Go and search carefully for the child. As soon as you find him, report to me, so that I too may go and worship him.”
  --Matthew 2:1-12 

(122:8.7) These wise men saw no star to guide them to Bethlehem. The beautiful legend of the star of Bethlehem originated in this way: Jesus was born August 21 at noon, 7 B.C. On May 29, 7 B.C., there occurred an extraordinary conjunction of Jupiter and Saturn in the constellation of Pisces. And it is a remarkable astronomic fact that similar conjunctions occurred on September 29 and December 5 of the same year. Upon the basis of these extraordinary but wholly natural events the well-meaning zealots of the succeeding generation constructed the appealing legend of the star of Bethlehem and the adoring Magi led thereby to the manger, where they beheld and worshiped the newborn babe. Oriental and near-Oriental minds delight in fairy stories, and they are continually spinning such beautiful myths about the lives of their religious leaders and political heroes. In the absence of printing, when most human knowledge was passed by word of mouth from one generation to another, it was very easy for myths to become traditions and for traditions eventually to become accepted as facts.
