By the end of the third century, most Christian leaders adhered to the paradoxical belief that the Creator is God, Christ is God, and the Spirit is God, whiles also insisting that there is only one God. However, they continued to be bitterly divided about how to explain the paradox. While some insisted that the one God simply appeared in three different forms (Modalism), an Alexandrian theologian named Arius articulated a different formula, by which the Creator was the sole uncreated eternal God, and Christ (while divine and unique as God’s Son) was nevertheless subordinate to the Creator. John Hamer of Toronto Centre Place will look at Arius’ understanding of the Godhead and the legacy of Arianism.
