Not if you deny the divinity of Jesus. Then St. Nick is less than jolly.
According to tradition, at the Council of Nicea, Nicholas, then Bishop of Myra, dealt with the heretic Arius by crossing the room and striking him in the face.

No, you're not free to believe about Jesus whatever you want, not if you value your salvation or your pretty-boy complexion.
