Whether the New Law justifies?

Objections

Objection 1 : It would seem that the New Law does not justify. For no man is justified unless he obeys God's law, according to Heb. 5:9: "He," i.e. Christ, "became to all that obey Him the cause of eternal salvation." But the Gospel does not always cause men to believe in it: for it is written (Rm. 10:16): "All do not obey the Gospel." Therefore the New Law does not justify.
Objection 2 : Further, the Apostle proves in his epistle to the Romans that the Old Law did not justify, because transgression increased at its advent: for it is stated (Rm. 4:15): "The Law worketh wrath: for where there is no law, neither is there transgression." But much more did the New Law increase transgression: since he who sins after the giving of the New Law deserves greater punishment, according to Heb. 10:28,29: "A man making void the Law of Moses dieth without any mercy under two or three witnesses. How much more, do you think, he deserveth worse punishments, who hath trodden underfoot the Son of God," etc.? Therefore the New Law, like the Old Law, does not justify.
Objection 3 : Further, justification is an effect proper to God, according to Rm. 8:33: "God that justifieth." But the Old Law was from God just as the New Law. Therefore the New Law does not justify any more than the Old Law.
