God the Son
In Latin "God the Son" is Deus (nominative) Filius (nominative). The term "deus filius" is found in the Athanasian Creed: "Et tamen non tres omnipotentes, sed unus omnipotens. Ita Deus Pater, Deus Filius, Deus [et] Spiritus Sanctus." (distinct from "filius Dei" genitive "son of God"), but this phrase is also translated "So the Father is God: the Son is God: and the Holy Ghost is God".
