Christmas, also known as Christmas Day, is translated as "Christian Mass", which originated from the Saturnalia in ancient Rome to welcome the New Year, and has nothing to do with Christianity.

After Christianity prevailed in the Roman Empire, the Holy See drifted into the Christian system to celebrate the birth of Jesus.

But Christmas is not the birthday of Jesus, because the Bible does not record the specific date when Jesus was born, nor does it mention the existence of such a festival, which is the result of Christianity absorbing ancient Roman mythology.

It is said that Jesus was conceived by the Holy Spirit and was born of the Virgin Mary. God even sent an angel Gabriel to Yue Se in a dream, telling him not to abandon Mary because she was unmarried and pregnant, but to marry her and name the child "Jesus", which means to save the people from their sins.

When Mary was about to give birth, the Roman government issued an order that all people must declare their household registration when they went to Bethlehem. Yue Se and Mary had to obey. When they arrived in Bethlehem, it was already dark, but they couldn't find a hotel to spend the night, only a stable could stay. Just then, Jesus was born. So Mary gave birth to Jesus only in a manger. In order to commemorate the birth of Jesus, later generations designated December 25th as Christmas, and observed mass every year to commemorate the birth of Jesus.
