Context

“Hence Christ cannot be said to be the servant of Himself, and consequently to be subject to Himself. Obj. 3: Further, "as the rational soul and flesh are one man; so God and man are one Christ," as Athanasius says (Symb. Fid.) . Now man is not said to be subject to himself or servant to himself or greater than himself because his body is subject to his soul. Therefore, Christ is not said to be subject to Himself because His Manhood is subject to His Godhead. On the contrary, Augustine says (De Trin. i, 7) : "Truth shows in this way" (i.e. whereby the Father is greater than Christ in human nature)” source
