Whether the fulness of grace is proper to Christ?

Objections

Objection 1 : It would seem that the fulness of grace is not proper to Christ. For what is proper to anyone belongs to him alone. But to be full of grace is attributed to some others; for it was said to the Blessed Virgin (Lk. 1:28): "Hail, full of grace"; and again it is written (Acts 6:8): "Stephen, full of grace and fortitude." Therefore the fulness of grace is not proper to Christ.
Objection 2 : Further, what can be communicated to others through Christ does not seem to be proper to Christ. But the fulness of grace can be communicated to others through Christ, since the Apostle says (Eph. 3:19): "That you may be filled unto all the fulness of God." Therefore the fulness of grace is not proper to Christ.
Objection 3 : Further, the state of the wayfarer seems to be proportioned to the state of the comprehensor. But in the state of the comprehensor there will be a certain fulness, since "in our heavenly country with its fulness of all good, although some things are bestowed in a pre-eminent way, yet nothing is possessed singularly," as is clear from Gregory (Hom. De Cent. Ovib.; xxxiv in Ev.). Therefore in the state of the comprehensor the fulness of grace is possessed by everyone, and hence the fulness of grace is not proper to Christ. on the contrary, The fulness of grace is attributed to Christ inasmuch as He is the only-begotten of the Father, according to Jn. 1:14: "We saw Him [Vulg.: 'His glory'] as it were . . . the Only-begotten of the Father, full of grace and truth." But to be the Only-begotten of the Father is proper to Christ. Therefore it is proper to Him to be full of grace and truth.
