I can't find a source to reference, but if I recall correctly, different sects of christianity even disagree about the books that make up the bible. The catholic bible has different books than the lutheran bible which has different books than the protestant bible, etc.
It would take a while but yes historical accounts of splits are documented. Take your council for example. They were split on Jesus' relationship with the father, issued clarification and modified the word. The great Martin Luther is another example. And let me tell ya, the Mormons see Christ in a WHOLE different way. In fact he visited them here in the USA and hung out for a while after his Crucifiction. Proably had some Merlot and crackers.
