It may, perhaps, be comforting to know that even one as holy and saintly as Santa Claus himself is not immune from wrath.
Saint Nicholas, upon him Santa Claus is based, lived in Anatolia around 300 CE. He became Bishop of Myra, and, it was said, led his flock capably, and successfully kept the heresy of Arianism at bay. In 325 CE, Constantine called together the First Council of Nicea, in order that the Chrstians might obtain a consensus on their religious beliefs and form a canon.
One of the largest disputes was over Arianism, the belief that Jesus Christ was created, rather than having existed forever with God. Allegedly, the debates over this matter became so heated that Nicholas punched Arius at the council, knocking him out.
In the end, Arianism was declared heretical, and its followers died out, its beliefs now almost entirely forgotten, remembered only by historians, theologians, and now, you.
