"Gift" as the Name of the Holy Ghost

The name gift in God is a personal name. A rational creature (man or angel) can possess God by or through a Person of the Trinity who is thus given to the creature.

This name gift in God is proper to the Third Person of the Trinity. A gift is the fruit of love. Love itself which dictates the giving is the first gift. Hence, as the Holy Ghost has the proper name of love, He is also properly called gift. St. Augustine (De Trin. vx) says,“By the gift which is the Holy Ghost, many particular gifts are bestowed on the members of Christ.”
