One of the earliest protesters in Christianity was Arius (256-336 CE), the fourth century priest in Alexandria, Egypt. He believed that God the Father created the universe through the divinely created Christ, but that Jesus was a creature. Athanasius, the Bishop of Alexandria disagreed. The Roman Emperor Constantine called a general council at Nicaea in 325 to settle this dispute. The result was the definition that Christ was the Son of the Father begotten of the same substance – homousious. Jesus was truly divine.
The Christian tradition believes in a monotheistic personal God who has had a unique presence in Jesus Christ. We truly care to live with the mysterious life of God who has an impact on our lives. The God of Israel was Yahweh, whom the Christians consider God the Father. There is also the presence of the Holy Spirit, the Spirit of Yahweh, that is present in our lives. Jesus is the Son of God, the Father.
