What is Monotheism?Monotheism has been defined as the belief in the existence of only one god. A god that created the world, is all-powerful and intervenes in the world. A broader definition of monotheism is the belief in one god. A distinction may be made between exclusive monotheism, and both inclusive monotheism and pluriform (panentheistic) monotheism which, while recognising various distinct gods, postulate some underlying unity.
Who was Arius?Arius 256-336 AD, was a Christian presbyter and ascetic of Berber origin, and priest in Baucalis in Alexandria, Egypt. His teachings about the nature of the Godhead in Christianity, which emphasized the Father's divinity over the Son, and his opposition to what would become the dominant Christology, Homoousian Christology, made him a primary topic of the First Council of Nicaea, which was convened by Emperor Constantine in 325 AD.
