“Grace joins the creature so closely to God that the soul, while it is in the state of grace, cannot be separated from God by any barrier of guilt. Grace, which bridges the infinite gap yawning between the creature and the divine nature, spans the still greater fissure caused by the upheaval of sin. By transforming man from a bondsman to a child of God, grace makes him also a friend of God, since God cannot but stand in a relation of friendship with His children as long as they remain His children. For this reason grace is called both gratia sanctificans (sanctifying grace) because it completely does away with all sinful disorder, and gratia gratum faciens (grace which renders one pleasing) because it makes the creature so pleasing in God’s sight that God myst deal with him as His friend and child.”
-Matthias Scheeben in The Mysteries of Christianity.
