Religious schism is a long and proud tradition. Just this week the United Methodists had to split into two. But schism is not limited to religion, it occurs in any kind of community of practice. No matter if they have been stated by a God or not, the rules are never quite clear, leaving room for edge cases that if pressed, can become wedges. Religious texts, like most others, are composed in natural language, and interpreted by the populations of the future: these are perfect conditions for textual disagreement. Consider the degree of controversy over the meaning of the Second Amendment of the U.S. Constitution, a very short text that is only two centuries old.
If a religious text can be written in a language of formal assertions that is meaningful now and into the future, I have yet to hear about it.
