From the only reliable source of Catholic news on the net, Eye of the Tiber:
The brawl broke out just after Cardinal Erdo appeared to have concluded his four day opening address to the bishops before informing them that he would begin the second half of his address after a short restroom break.
Footage obtained by EOTT shows a tired and disgruntled Cardinal Walter Kasper screaming at Erdo to “shut up and get on with the communion divorce stuff” when Archbishop Charles Chaput picks up what looks to be a thurible, lights it on fire, swings it around a few times before finally launching at the head of the German Cardinal.
“It was amazing how quickly it all escalated,” one witness told EOTT. “Next thing you know, a German bishop comes in throwing copies of Laudato Si like ninja stars at people. Lot of people were hit. Blood everywhere.”
The video also shows Cardinal Robert Sarah being helped up on a horse before being handed a shield and sword, and is then heard trying to motivate his side of cardinals during a 15-minute hiatus in the brawl.
“I am Cardinal Sarah,” Sarah is seen shouting to a large number of cardinals in front of him. “And I see a whole army of my fellow bishops, here in defiance of sin! You have come to fight as orthodox men. And orthodox men you are! What will you do without orthodoxy? Will you fight?”
“Yes!” Sarah is heard shouting back. “Fight and you may die. Run and you will live and give communion to divorced and remarried couples at least awhile. And dying in your rectory many years from now, would you be willing to trade all the days from this day to that for one chance, just one chance, to come back here as aging and balding men and tell our enemies that they may take our lives, but they will never distort our doctrine! Oh, wait, they’re distorting our doctrine. Aren’t those German bishops a sneaky bunch. Everyone run.”
PopeWatch attempted to call the Vatican for comment but after a Swiss Guard answered the phone and began singing a Swiss military anthem, he decided to try again at a later time.
