Most educated people--those who specialize in biblical scholarship in particular--understand that no one was ordained at the last supper, nor was Jesus himself ordained in the Roman sense of the word. Anyone who teaches such nonsense could be (and should be) labeled a heretic, and that might account for some of the superfluous dogma and doctrine that certain self-serving prelates have enshrined over the centuries.  

Incidentally, I would venture a guess that you're not a big fan of papal infallibility right about now... but since you have surrendered your will and intellect to the "holy" Roman See I guess you are stuck with it now.
