...Do you really think that the Protestant Reformation was the first major schism in the Christian Church?
If so, you really need to read up more on things like Oriental Orthodoxy and Eastern Orthodoxy.
I never said I thought it was a first, I was responding to someone else's example.
And again, those were not "friendly" separations. The catholic church was in no way consenting to or even recognizing the creation of the orthodox church. What's more, the amount of heresies squashed out by the church outnumbers the few times where (major) opposing churches were successfully established.
