Whether there is but one Divine law?

Objections

Objection 1 : It would seem that there is but one Divine law. Because, where there is one king in one kingdom there is but one law. Now the whole of mankind is compared to God as to one king, according to Ps. 46:8: "God is the King of all the earth." Therefore there is but one Divine law.
Objection 2 : Further, every law is directed to the end which the lawgiver intends for those for whom he makes the law. But God intends one and the same thing for all men; since according to 1 Tim. 2:4: "He will have all men to be saved, and to come to the knowledge of the truth." Therefore there is but one Divine law.
Objection 3 : Further, the Divine law seems to be more akin to the eternal law, which is one, than the natural law, according as the revelation of grace is of a higher order than natural knowledge. Therefore much more is the Divine law but one.
