Monotheistic refers to the belief in a single, all-powerful deity. This concept is central to several major religions, including Christianity, Islam, and Judaism. In monotheistic faiths, followers worship one God who is often seen as the creator and sustainer of the universe. In contrast to polytheism, which involves the worship of multiple gods, monotheism emphasizes the oneness and uniqueness of God. This belief shapes the moral and ethical guidelines of its adherents, influencing their practices, rituals, and worldview. Monotheistic religions often have sacred texts that outline their teachings and beliefs.
