More than 200 people dressed in period clothes took part in the reenactment...
The pope greeted all of the participants and many of the parishioners who attended the lively event.
The live nativity is held annually to celebrate the day when the three kings, or Magi, arrived in Bethlehem to pay homage to the baby Jesus.
While visiting the "shepherds," the pope made friends with a lamb...
And carried the baby sheep on his shoulders.
Here's a video of the incredibly cute visit.
