Christmas on December 25th?
A rather interesting article can be found HERE, which is based on research which purports to show that the Christian celebration of December 25th as Christ's birthday does not neccesarily find its origin in the "conversion" of a pagan festival, but instead may more truthfully reflect ancient Judaic-Christian thought in regards to time. A thinking, which I believe the Orthodox Church has preserved in the use of her living Liturgical Calender.
Warning, the news reporter who wrote this article makes a huge factual error - albeit a very very common one. Let me, once again say very loudly: CONSTANTINE DID NOT MAKE CHRISTIANITY THE OFFICIAL RELIGION OF THE ROMAN EMPIRE! (sigh)
