(Part 1)
Around 200 A.D., Clément of Alexandria, a Gentile
Christian theologian in Egypt, made the first known reference to the date/s
Jesus Christ was born. About the same time, Clément's student, Origen (c.
165–264 A.D.), another Gentile Egyptian Christian, mocked as “pagan” the Roman
practice of celebrating birthdays. (Origen, Homily on Leviticus 8). Despite
Origen’s censure -- and according to Clément, Origen’s mentor -- a couple of
different days had been proposed at that time by various Christian groups.
Surprising as it may seem to Roman Catholics and Protestants, Clément doesn't
mention December 25 at all!
