Here's the guy who was really born on December 25th, the day after the third day that the sun seems to hover moribund on the horizon.
In the early history of the Catholic Church, Christianity struggled against a religion called Mithraism. A huge number of Romans were followers of Mithras at the time when the Christian religion was developing.
The central figure of Mithraism was Mithras, a sun god, and he was born on December 25th. He promised eternal life. His followers ate bread and drank wine in their services. Every reputable scholar points out that, yes, Mithras' birthday was December 25th, well before the Church declared Jesus's birthday to be December 25th.
Why December 25th? December 22,23,24 are the shortest days of the year with the sun just hovering weakly over the horizon, looking dead. On December 25th, it is as if the sun is born again as the days begin to lengthen and the sun seems to move higher in the sky each day.
Apparently the Church declared that Jesus's birthday was on December 25th in order to effectively compete with Mithraism. This sounds strange? Yes! It is strange, but it is supported by scholarship.
It turns out that every major Christian holiday - especially Easter and Christmas - was established on a big "pagan" or pre-Christian holiday. Scholars believe this was a deliberate act by the Church to compete with the non-Christian religions and to replace those religions. Merry Mithramas.
Don't believe me? Here is the ground-breaking research by an amazing scholar:
Merry Mithrasmas!!!!!!!! Happy Birthday Baby Mithras!!!!!
