Reply Obj. 1: Faith and hope signify effects of grace with certain defects on the part of the recipient of grace, inasmuch as faith is of the unseen, and hope of what is not yet possessed. Hence it was not necessary that in Christ, Who is the author of grace, there should be any defects such as faith and hope imply; but whatever perfection is in faith and hope was in Christ most perfectly; as in fire there are not all the modes of heat which are defective by the subject's defect, but whatever belongs to the perfection of heat.
Reply Obj. 2: It pertains essentially to operating grace to justify; but that it makes the ungodly to be just is accidental to it on the part of the subject, in which sin is found. Therefore the soul of Christ was justified by operating grace, inasmuch as it was rendered just and holy by it from the beginning of His conception; not that it was until then sinful, or even not just.
Reply Obj. 3: The fulness of grace is attributed to the soul of Christ according to the capacity of the creature and not by comparison with the infinite fulness of the Divine goodness. _______________________
TENTH ARTICLE [III, Q. 7, Art. 10]
Whether the Fulness of Grace Is Proper to Christ?
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 (Luke 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.
Obj. 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.
Obj. 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 John 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.
I answer that, The fulness of grace may be taken in two ways: First, on the part of grace itself, or secondly on the part of the one who has grace. Now on the part of grace itself there is said to be the fulness of grace when the limit of grace is attained, as to essence and power, inasmuch as grace is possessed in its highest possible excellence and in its greatest possible extension to all its effects. And this fulness of grace is proper to Christ. But on the part of the subject there is said to be the fulness of grace when anyone fully possesses grace according to his condition—whether as regards intensity, by reason of grace being intense in him, to the limit assigned by God, according to Eph. 4:1: "But to every one of us is given grace according to the measure of the giving of Christ"—or "as regards power," by reason of a man having the help of grace for all that belongs to his office or state, as the Apostle says (Eph. 3:8): "To me, the least of all the saints, is given this grace . . . to enlighten all men." And this fulness of grace is not proper to Christ, but is communicated to others by Christ.
Reply Obj. 1: The Blessed Virgin is said to be full of grace, not on the part of grace itself—since she had not grace in its greatest possible excellence—nor for all the effects of grace; but she is said to be full of grace in reference to herself, i.e. inasmuch as she had sufficient grace for the state to which God had chosen her, i.e. to be the mother of His Only-begotten. So, too, Stephen is said to be full of grace, since he had sufficient grace to be a fit minister and witness of God, to which office he had been called. And the same must be said of others. Of these fulnesses one is greater than another, according as one is divinely pre-ordained to a higher or lower state.
