Your question is extremely vague, however, it is true that religion is often subject to disagreement.
Plato and Aristotle disagreed on various issues, including the nature of reality, the concept of forms, the role of reason, and the ideal state.

Plato also advocated for philosopher-kings ruling the ideal state, whereas Aristotle believed in a more democratic form of government.
