So let me get this straight: you believe the first eleven chapters of Genesis are mythology . . . but that J*sus was literally born on the 25th of December?
::Facepalm::
You folks are getting desperate.
Relax ZC. I do not believe Genesis 1-11 are mythology.
As for Jesus being born on the 25th of December, you show me some contrary evidence. Like I said, Hippolytus mentions it specifically around 200. Chrysostom calls it an immemorial tradition of the Roman Church based on the census records.
Actually, if I had to guess I’d say there was an underlying Hebrew date (25 Kislev?), which was conflated with the Incarnation and rendered into the local calendars haphazardly (25 Pachon, 25 Pharmuthi, January 6th).
