Actually, no... different people understand God in different ways. It all depends on someone's point of view, since every person perceives reality differently than everyone else.
It depends... if different denominations coexist together peacefully and realize that they all perceive the truth about God in different ways, then it's not a "broken body". I think it only becomes broken when denominations start fighting with each other and claiming that they are right about everything and all other denominations are wrong.
Yes, some people do that...
What one person believes to be the "word of God" can be different than what another person believes to be the "word of God". In reality, everyone depends on their own understanding, because that's all each person has... everything you know, and everything you see, is in your own, imperfect mind... no person has perfect, absolute knowledge.
