Reply Obj. 2: Powers and habits are diversified by comparison with their objects. Hence in this way the diversity of operations corresponds to the divers powers and habits, as likewise to the divers objects. Now we do not wish to exclude this diversity of operations from Christ's humanity, nor that which springs from a diversity of time, but only that which regards the first active principle, as was said above.
(St. Thomas gives no reply to Obj. 3; some codices add: Hence may be gathered the reply to the third objection.) _______________________
THIRD ARTICLE [III, Q. 19, Art. 3]
Whether the Human Action of Christ Could Be Meritorious to Him?
Objection 1: It would seem that the human action of Christ could not be meritorious to Him. For before His death Christ was a comprehensor even as He is now. But comprehensors do not merit: because the charity of the comprehensor belongs to the reward of beatitude, since fruition depends upon it. Hence it does not seem to be the principle of merit, since merit and reward are not the same. Therefore Christ before His passion did not merit, even as He does not merit now.
Obj. 2: Further, no one merits what is due to him. But because Christ is the Son of God by nature, the eternal inheritance is due to Him, which other men merit by their works. And hence Christ Who, from the beginning, was the Word of God, could not merit anything for Himself.
Obj. 3: Further, whoever has the principle does not properly merit what flows from its possession. But Christ has the glory of the soul, whence, in the natural course, flowed the glory of the body, as Augustine says (Ep. ad Dios cxviii); though by a dispensation it was brought about that in Christ the glory of the soul should not overflow to the body. Hence Christ did not merit the glory of the body.
Obj. 4: Further, the manifestation of Christ's excellence is a good, not of Christ Himself, but of those who know Him. Hence it is promised as a reward to such as love Christ that He will be manifested to them, according to John 14:21: "He that loveth Me, shall be loved of My Father, and I will love him and will manifest Myself to him." Therefore Christ did not merit the manifestation of His greatness.
On the contrary, The Apostle says (Phil. 2:8, 9): "Becoming obedient unto death . . . For which cause God also hath exalted Him." Therefore by obeying He merited His exaltation and thus He merited something for Himself.
I answer that, To have any good thing of oneself is more excellent than to have it from another, for "what is of itself a cause is always more excellent than what is a cause through another," as is said Phys. viii, 5. Now a thing is said to have, of itself, that of which it is to some extent the cause. But of whatever good we possess the first cause by authority is God; and in this way no creature has any good of itself, according to 1 Cor. 4:7: "What hast thou that thou hast not received?" Nevertheless, in a secondary manner anyone may be a cause, to himself, of having certain good things, inasmuch as he cooperates with God in the matter, and thus whoever has anything by his own merit has it, in a manner, of himself. Hence it is better to have a thing by merit than without merit.
