Whether the grace of Christ is infinite?

Objections

Objection 1 : It would seem that Christ's grace is infinite. For everything immeasurable is infinite. But the grace of Christ is immeasurable; since it is written (Jn. 3:34): "For God doth not give the Spirit by measure to His Son [*'To His Son' is lacking in the Vulgate], namely Christ." Therefore the grace of Christ is infinite.
Objection 2 : Further, an infinite effect betokens an infinite power which can only spring from an infinite essence. But the effect of Christ's grace is infinite, since it extends to the salvation of the whole human race; for He is the propitiation for our sins . . . and for those of the whole world, as is said (1 Jn. 2:2). Therefore the grace of Christ is infinite.
Objection 3 : Further, every finite thing by addition can attain to the quantity of any other finite thing. Therefore if the grace of Christ is finite the grace of any other man could increase to such an extent as to reach to an equality with Christ's grace, against what is written (Job 28:17): "Gold nor crystal cannot equal it," as Gregory expounds it (Moral. xviii). Therefore the grace of Christ is infinite.
