The Patriarch stated he would rather be under Islam occupation than get the Latins to come help! That’s how terrible it was. It was a completely messed up thing going in there and destroying everything and sending stuff back to Venice as booty. The city never recovered from that. It would still be Constantinople if the Venicians hadn’t done that. Maybe not for sure but it really messed stuff up. And not to mention there were talks prior to this of reunification.
I am Catholic but I also studied history and I’m tired of Catholics blaming the schism on the east as if they had no part in it. The fact is both sides are to blame. It was ignored for centuries, officially happened in 1054 but was utterly certain in 1204. So complicated. The papal supremacy part really was not nearly as much to do with it as people make it out. Nor was papal supremacy as big of a deal until the schism. Before that the bishop of Rome was the first among equals. Which now the patriarch of Constantinople holds the title being new Rome. I am not going to get much into it but it was both sides fault.
