Whether a man can merit the first grace for another?

Objections

Objection 1 : It would seem that a man can merit the first grace for another. Because on Mt. 9:2: "Jesus seeing their faith," etc. a gloss says: "How much is our personal faith worth with God, Who set such a price on another's faith, as to heal the man both inwardly and outwardly!" Now inward healing is brought about by grace. Hence a man can merit the first grace for another.
Objection 2 : Further, the prayers of the just are not void, but efficacious, according to James 5:16: "The continued prayer of a just man availeth much." Now he had previously said: "Pray one for another, that you may be saved." Hence, since man's salvation can only be brought about by grace, it seems that one man may merit for another his first grace.
Objection 3 : Further, it is written (Lk. 16:9): "Make unto you friends of the mammon of iniquity, that when you shall fail they may receive you into everlasting dwellings." Now it is through grace alone that anyone is received into everlasting dwellings, for by it alone does anyone merit everlasting life as stated above (Article [2]; Question [109], Article [5]). Hence one man may by merit obtain for another his first grace.
