Arianism
God's communication with the world is known as the "Son of God" or the "Christ". The Son of God existed before he helped his Father make man.  He is the perfect image of God the Father. There is one exception though: Unlike God the Father, he was created (from nothing) by the will of the Father. This happened at the beginning of time. Therefore, he is not eternal. There was a time when he was not there. In the same way, his power, his wisdom and his knowledge are limited.
