Christmas is just around the corner, which means it’s time for another Christmas tradition: articles start appearing on the Internet explaining how 1.) Jesus wasn’t actually born on December 25th, 2.) December 25th was actually the time of some pagan holidays, which means that the Christians picked the 25th to suborn paganism and 3.) this is some sort of earth-shattering revelation that disproves Christianity.
Two sorts of people seem to write these articles. One, of course, is your garden-variety Angry Internet Atheist, one much the same as the other. The other sort, oddly enough, is a Christian, though of a more Calvinistic strain, the “comfortable clothing is of the devil” school.
“Do you know,” they’ll say, solemnly, “that the word ‘Christmas’ never appears in the Bible?”
“Yeah,” I’ll say, “but technically there are no English words in the Bible. So why aren’t you talking at me in koine Greek?”
Anyway. Here is a point by point reasoning for why Christmas isn’t just a Christian rebranding of the Roman Festival of Sol Invictus or something like that:
“1.) Jesus wasn’t actually born on December 25th.”
No one actually knows when Jesus was born. The ancient Romans had a mania for order, but even they did not keep records on the scale of a modern bureaucracy, and certainly they didn’t bother to record the births of provincials. So if you want to celebrate Christ’s birth, you’re basically going to have to pick a day for it.
Now, why did the ancient Christians pick December 25th? It turns out that the ancient Christians were much more interested in the date of Jesus’s death than his birth, since the Resurrection was a bigger deal than the Nativity. Eventually, they settled on March 25th on the date of the Crucifixion.
(An aside: that’s the reason J.R.R. Tolkien picked March 25th as the day of the destruction of the Ring and the defeat of Sauron in “The Lord of the Rings”.)
A second tradition came into play. Ancient Judaism had this idea of the “integral age” of their prophets, that a Jewish prophet always died on the same day of his conception. So, if you assume that the date of Jesus’s conception and death were both March 25th, and you add nine months to that…ta-da! You’ve got December 25th.
(In Eastern Christianity, the tradition held that Jesus died on April 6th, which is why Eastern churches usually celebrate the Nativity on January 6th/7th.)
“2.) December 25th was actually the time of some pagan holidays, which means that the Christians picked the 25th to suborn paganism.”
Actually, it’s funny. It turns out the reverse is true.
A guy named Aurelian was Roman Emperor from 270-275, and he was a seriously competent general; he hammered the Roman Empire back into once piece after it split into three fragments during the preceding fifteen years of civil war, and curbstomped a barbarian invasion that almost got to Rome itself. However, the Roman Empire was still a wreck, and Aurelian really did not like Christians. So in 274 he instituted the cult of Sol Invictus, the unconquered sun, as the state cult, in hopes of giving the Empire something to rally around. Just as the sun would rise from the winter solstice, so too would the Empire arise anew out of its present troubles, or so Aurelian hoped. Aurelian probably picked December 25th to suborn the Christians (who he did not like, remember) who were already celebrating December 25th as the birth of Christ.
And how do we know that the Western Christians had already chosen December 25th? By the life of Tertullian, Western Christians had concluded that Jesus died on March 25th, 29 AD, and Tertullian died fifty years before Aurelian even became Emperor.
Another common trope is that December 25th was originally the birth of the pagan god Mithras, who like Jesus was allegedly born of a virgin. However, there is not a lick of evidence that December 25th was a big deal for Mithraism. For that matter, Mithras was not born of a virgin. According to his cult, he sprang full-grown out of a rock, like Athena bursting full-grown (and armed to the teeth) from the brow of Zeus. There’s bit of a difference between some full-grown dude stepping out of a rock and a woman who has never had sexual intercourse giving birth to an infant son.
“3.) This is some sort of earth-shattering revelation that disproves Christianity.”
How, precisely? The gist of Christianity is that Jesus was the Son of God who died and rose again from the dead to redeem humanity from its willfully corrupted state. The fact that we celebrate the date of his birth on December 25th out of long-standing tradition does not invalidate that, let alone disprove it.
