" The Word bestows adoption on us when he grants us that birth and deification which, transcending nature, come by grace from above through the Spirit. The guarding and preservation of this in God depends on the resolve of those thus born: on their sincere acceptance of the grace bestowed on them and, through the practice of the commandments, on their cultivation of the beauty given to them by grace. Moreover, by emptying themselves of the passions they lay hold of the divine to the same degree as that to which, deliberately emptying himself of his own sublime glory, the Word of God truly became man.
