Religious doctrines are the official beliefs and teachings of a particular faith or religion. They provide guidelines for followers on how to live their lives, understand the nature of the divine, and interact with others. Doctrines can include sacred texts, rituals, and moral principles that shape the community's values and practices. Different religions have their own unique doctrines. For example, in Christianity, the doctrine of the Trinity explains the nature of God as three persons in one. In Islam, the Five Pillars outline essential practices that every Muslim should follow. These doctrines help maintain the identity and unity of religious communities.
