Pope Boniface II may be the only Anti-Pope that is officially a Pope. The previous Pope,Felix IV,was on his deathbed when he chose Boniface II to replace him as Pope. This is a major violation of the rules of electing a new Pope. Felix IV himself was appointed and not elected so I guess he thought this was just par for the course now. The Pope is supposed to be voted on and elected by the clergy,and the clergy promptly ignored Boniface II and got to work on electing a man named Dioscorus as their new “official” Pontiff. The dueling Popes were consecrated on the same day and the Church seemed destined for conflict,but poor Dioscorus only lived for about 20 days. Boniface II was now the official Pope and the clergy grudgingly accepted him. He did try to appoint his own successor,having not learned anything,and he was promptly shouted down. Rome would only have to put up with him for two years before he passes away from natual causes. Boniface’s only contribution,which is pretty major in the long term,is his changing the years in the Julian calendar from Ab Urbe Condita to Anno Domini. Anno Domini is the numbering we use now,but during the time of Pope Boniface II,it would still be about 300 more years before the rest of the world got on board with the new Christ-centered numbering system……..so Boniface probably only succeeded in just confusing the Hell out of everyone.
