Look… Im sure this is not the first time the pope has been called the antichrist. It likely happened in 884, 964, 997, 1012, 1378, 1409, or 1418 to just name a few.
(This is not be taken seriously, I grabbed a bunch of years from the Wikipedia list of antipoes to make a point when the role was contested. In the case of the ones between 1378-1418, where a bloody mess is an understatement (I would rather read history on the war of the roses), there have been significantly fewer violent disagreements regarding the title/position since then)

Hell I’m sure you could probably throw a bunch of even earlier dates in from back when the Catholics and Orthodox were united under the Chalcedonian Roman Church.
