"...a begotten Son inherent in the Father's nature is a single Son, the unique and utterly final Word of the Father. Creatures become "sons," not the Son. They are "gods" (Psalm 82:6), not God as the Father is God." - Leithart, Athanasius, p69.
This, in response to the Arians' desire to make Jesus one of many sons of God. Jesus is the final word. Our words are fragmentary, partial, and temporary. The Son, Who is the Word, is a Word which is stable, single, and final. There is no fragmentation of God or His Word. This is part of the great Creature/creation divide.
