How does the leader of a theocracy get power?

In a theocracy, the leader typically derives power from religious authority, claiming to be divinely appointed or guided by a higher spiritual force. This leader often holds a significant position within a religious institution, such as a clergy member or religious scholar, and their legitimacy is reinforced by the belief of the population in their spiritual role. Governance is intertwined with religious doctrine, and laws are often based on religious texts, further consolidating the leader's power through both spiritual and political means.
