We should always be together as a church since we are the same religion
Well actually no because I don't like how you Romans think that icons can be represented as our religion, I hate that and I won't allow it!
Why? I thought we were on the same team, Well either way that's what we believe in so yeah, I'm the one who's ruling here so I get to pick what we allow here on this church and what we don't!
Well you know what, I decided to create my own side of this religion and I excommunicate you from mine. I don't want to argue with people who think they are the best so good bye.
Ok fine, good bye forever I guess. I guess we can call this a schism since we are still the same religion but different beliefs.
