Christmas supposedly commemorates the birth of Jesus Christ, and nearly every religion that claims to be Christian celebrates it, yet, there is no evidence that the first century disciples of Jesus observed such a holiday. "For two centuries after Christ's birth, no one knew, and few people cared, exactly when he was born."
Even if Jesus' disciples had known the exact date of his birth, they would not have celebrated it. why? Because, as The World Book Encyclopedia says, the early Christians "considered the celebration of anyone's birth to be a pagan custom."
Birthday celebration were associated with paganism, not with Christianity.
How did Christmas come to be celebrated by many people?
It was not until several hundred years after Jesus lived on the earth that people began to commemorate his birth on December 25. But that was not the date of Jesus birth, it evidently took place in October. So why was December 25 chosen? Some who later claimed to be Christian "wished the date to coincide with the pagan Roman festival, that marked the birthday of the unconquered sun."
In an effort to convert pagans, religious leaders adopted this festival and tried to make it seem "Christian."
The pagan roots to Christmas have long been recognized. Because of its unscriptural origin.
