The Pope and the Patriarch had a big disagreement on Icons. The western half thought it was fine and the eastern half didn't.
You can’t worship an icon because it bring you away from God.
Here are some example of icon. The first one starting from the left is a gold statue that they would act as if it was God. The next one is a gold plate mosaic they would worship. The next one is a copper statue on a wood plat form.
The Pope and the Patriarch also disagreed on if they could marry or not. The western half though it was okay and the eastern half thought you wouldn't be able to focus on God enough.
You can't be married if your the Pope.
I'm sorry being a patriarch I can't marry because I need to focus on God!
The eastern half thought that marrying will bring you away from God and they also thought that the Pope should definitely not be married because is the one who teaches about God. But the western half thought the Pope deserved marrying as a privilege.
Will you marry me??
Another thing they disagreed about is how the Pope got paid and the Patriarch didn't. Also the eastern half wanted to live on the western half and the western half didn't want them there.
