Once upon a time, long, long ago, a tiny little meeting was held, called the Council of Nicea. You may have heard of it. Among those who attended was one St. Nick, the man himself... known more properly as (Now- Saint) Bishop Nicholas of Myra.
The year was 325AD, and the holy men of the world set about nailing down what was believed, what was doctrine, once and for all.
One Arius, out of Egypt, argued that Jesus the Son was not equal to either Father or Spirit. He even came up with a catchy jingle, which had to irritate far worse than the old Round Up weed killer ads put out by Monsanto.
To wit: "If you want the Logos Doctrine, I can give it hot and hot. God begat him, and before he begat him, he was NOT."
Logos is Latin for "Word".
Along with assertions of doubt that Jesus was both divine and human. He was so nasty, so vehement, that the good Bishop lost his cool and punched Arius in the head. The Bishop was expelled, but forgiven and returned at the next session. At last, things were ironed out and the Nicean creed is now said to this day- "I believe in God the Father, God the Son, and God the Holy Spirit, as was in the beginning, is now, and shall ever be, world without end, amen."
Things did not end so well for Arius, who died of an intestinal prolapse, causing his former peers to say it was divine punishment. You see, in laymens' terms, Arius' butt fell out of itself. Ow.
Other than Arius, our heroes lived happily ever after. You know, until the sixteenth century or so- and that darned destructive Reformation.
Imagine if it had gone the other way. Arius Klaus. Shudder!
