One Powerful God, But Just One

"God must be strong:  his "eternal power" is manifest in creation (Rom 1:18-20).  God must also be one:  "If there were many gods, there ought to be many worlds" since "it would not be becoming that the many produced only one world nor that the one world were made by many gods" (Against the Pagans 39).  How can the world go in one direction without a single pilot?  How can creation produce its harmonious sound unless it is played by a single artist? (Against the Pagans 39).  In short, "because the world which has been made is one, one must also believe that its Maker is one" (Against the Pagans 39)." - Leithart, Athanasius, p98.
