The Great Schism
Differences between the West and East
No Marriage Here
The West said that their clergy were not allowed to marry.
Sure, Start a Family
In the East, however, the clergy were allowed to marry.
The Roman Catholic Church allowed the veneration of icons, because they helped people.
The Eastern Orthodox Church said it was considered worshipping idols, and did not allow it. They did accept icons later, however.

The Pope was the ruler in the West...
Pope, no thanks!
The East rejected supremacy of the Pope ruling all, and had a Patriarch as head instead.
