Whether the New Law should have been given from the beginning of the world?

Objections

Objection 1 : It would seem that the New Law should have been given from the beginning of the world. "For there is no respect of persons with God" (Rm. 2:11). But "all" men "have sinned and do need the glory of God" (Rm. 3:23). Therefore the Law of the Gospel should have been given from the beginning of the world, in order that it might bring succor to all.
Objection 2 : Further, as men dwell in various places, so do they live in various times. But God, "Who will have all men to be saved" (1 Tim. 2:4), commanded the Gospel to be preached in all places, as may be seen in the last chapters of Matthew and Mark. Therefore the Law of the Gospel should have been at hand for all times, so as to be given from the beginning of the world.
Objection 3 : Further, man needs to save his soul, which is for all eternity, more than to save his body, which is a temporal matter. But God provided man from the beginning of the world with things that are necessary for the health of his body, by subjecting to his power whatever was created for the sake of man (Gn. 1:26-29). Therefore the New Law also, which is very necessary for the health of the soul, should have been given to man from the beginning of the world.
