We don't celebrate Christmas in our Church, as December the 25th is not when Jesus was born. The exact month or day of His birth is unknown. Dec 25th is believed to be a pagan Roman feast day, when they used to pay homage to one of their gods.
Most people are happy to give gifts and be kind on Christmas day but they always go back to hatred for the other 364 days of the year. Even unbelievers can go along with the crowd for a day, but we need people to be loving and peaceful all year round.
