Whether all men were bound to observe the Old Law?

❌ Objection 1 : It would seem that all men were bound to observe the Old Law. Because whoever is subject to the king, must needs be subject to his law. But the Old Law was given by God, Who is "King of all the earth" (Ps. 46:8). Therefore all the inhabitants of the earth were bound to observe the Law.

❌ Objection 2 : Further, the Jews could not be saved without observing the Old Law: for it is written (Dt. 27:26): "Cursed be he that abideth not in the words of this law, and fulfilleth them not in work." If therefore other men could be saved without the observance of the Old Law, the Jews would be in a worse plight than other men.

❌ Objection 3 : Further, the Gentiles were admitted to the Jewish ritual and to the observances of the Law: for it is written (Ex. 12:48): "If any stranger be willing to dwell among you, and to keep the Phase of the Lord, all his males shall first be circumcised, and then shall he celebrate it according to the manner; and he shall be as he that is born in the land." But it would have been useless to admit strangers to the legal observances according to Divine ordinance, if they could have been saved without the observance of the Law. Therefore none could be saved without observing the Law.
