Whether the Old Law should have been given to the Jews alone?

Objections

Objection 1 : It would seem that the Old Law should not have been given to the Jews alone. For the Old Law disposed men for the salvation which was to come through Christ, as stated above (Articles [2],3). But that salvation was to come not to the Jews alone but to all nations, according to Is. 49:6: "It is a small thing that thou shouldst be my servant to raise up the tribes of Jacob, and to convert the dregs of Israel. Behold I have given thee to be the light of the Gentiles, that thou mayest be My salvation, even to the farthest part of the earth." Therefore the Old Law should have been given to all nations, and not to one people only.
Objection 2 : Further, according to Acts 10:34,35, "God is not a respecter of persons: but in every nation, he that feareth Him, and worketh justice, is acceptable to Him." Therefore the way of salvation should not have been opened to one people more than to another.
Objection 3 : Further, the law was given through the angels, as stated above (Article [3]). But God always vouchsafed the ministrations of the angels not to the Jews alone, but to all nations: for it is written (Ecclus. 17:14): "Over every nation He set a ruler." Also on all nations He bestows temporal goods, which are of less account with God than spiritual goods. Therefore He should have given the Law also to all peoples.
