It is said that Jesus was conceived by the Holy Spirit and was born of the Virgin Mary. God also sent an envoy Gabriel to speak to Yue Se in a dream, asking him not to reject Mary because she was unmarried and pregnant, but to marry her and call the child "Jesus", meaning that he would save the people from their sins.
When Mary was about to give birth, the Roman government ordered all the people to declare their household registration in Bethlehem.
Yue Se and Mary had to obey. When they arrived in Bethlehem, it was already dark, but the two were unable to find a hotel to spend the night, and there was only one stable to stay in.
Just then, Jesus was about to be born. So Mary only gave birth to Jesus in the manger. Later, to commemorate the birth of Jesus, December 25 was designated as Christmas and mass was held every year to commemorate the birth of Jesus.
