What is the primary characteristic of monotheism?

The primary characteristic of monotheism is the belief in a single all-powerful deity. This definition clearly distinguishes monotheism from polytheism, which involves the worship of multiple gods, as well as animism, which focuses on spirits in nature. Monotheistic faiths emphasize the existence and singularity of one ultimate divine being who is often regarded as the creator and sustainer of the universe. This unique belief system shapes the theological, moral, and philosophical frameworks within various religious traditions, influencing practices and community life. Monotheism is a foundational aspect of religions such as Judaism, Christianity, and Islam, all of which affirm the unity and supremacy of one God, making it a central tenet of those faiths.
