The 25th December was celebrated in ancient days as the birthday of the unconquerable SUN god, (variously know as Tammuz, Mithra, Saturn, Adonis or BAAL) centuries before Jesus Christ was born in Bethlehem.
Nowhere in the Bible are believers in the God of Abraham, Isaac and Jacob required to celebrate Christmas.
The early Christian church did not celebrate Christmas. Instead it celebrated the sacred festivals mentioned in the Bible, in Leviticus chapter 23.
In order to win Gentile converts to the Christian faith, the Roman Church, centuries after the apostolic era, adopted this ancient pagan winter festival of the SUN god and renamed it ‘Christmas’ mistakenly thinking that it would honour the SON of God.
Scholars have for centuries known these facts. They can be confirmed in any reference library.
