Pictured above is my favorite meme of the season (HT: Mary Moerbe). The point is that the “real St. Nicholas” was said to be at the Council of Nicaea, where a major theme of the debate was whether Christ was “homoousios”–meaning “one substance”–with the Father, or “homoioousios”–of similar substance with the Father. In other words, is Christ truly God, as St. Nicholas and the other orthodox bishops believed, or is He just similar to God, a very special creation, but just Man and not God, as Arius and his faction believed.
St. Nicholas was so zealous for the deity of Christ that he actually is said to have assaulted Arius. (I wrote about this in a column for WORLD that keeps circulating on the internet. But read my updated, more historically-accurate version here.)
