There is ample evidence to demonstrate that, even though the Christmas date was not made official until 354, clearly it was established long before Aurelian instituted his pagan feastday. John the Baptist is the historical anchor to know the date of Christmas, based on the detailed and careful calculations on dates made by first Fathers of the Church.
His birth would thus be in late December at the time of the winter solstice.Such assertions are blatantly absurd, given the countless source documents demonstrating the opposite.The two principal claims for Christmas having pagan origins pretend that the early Church chose December 25 in order to divert Catholics from Roman pagan festival days.They abhorred the feast days and in particular, they detested the Christmas feast with its joyous ceremonies, celebrations and customs.
Since the Bible gave no specific date of Christ’s birth, the Puritans argued that it was a sinful contrivance of the Roman Catholic Church that should be abolished.
(5) The Catholic Church determined March 25 as the date of Our Lord’s Conception long before Aurelian decided to make his solar feast.
