Whether the precepts of the decalogue are dispensable?

❌ Objection 1 : It would seem that the precepts of the decalogue are dispensable. For the precepts of the decalogue belong to the natural law. But the natural law fails in some cases and is changeable, like human nature, as the Philosopher says (Ethic. v, 7). Now the failure of law to apply in certain particular cases is a reason for dispensation, as stated above (Question [96], Article [6]; Question [97], Article [4]). Therefore a dispensation can be granted in the precepts of the decalogue.

❌ Objection 2 : Further, man stands in the same relation to human law as God does to Divine law. But man can dispense with the precepts of a law made by man. Therefore, since the precepts of the decalogue are ordained by God, it seems that God can dispense with them. Now our superiors are God's viceregents on earth; for the Apostle says (2 Cor. 2:10): "For what I have pardoned, if I have pardoned anything, for your sakes have I done it in the person of Christ." Therefore superiors can dispense with the precepts of the decalogue.

❌ Objection 3 : Further, among the precepts of the decalogue is one forbidding murder. But it seems that a dispensation is given by men in this precept: for instance, when according to the prescription of human law, such as evil-doers or enemies are lawfully slain. Therefore the precepts of the decalogue are dispensable.

❌ Objection 4 : Further, the observance of the Sabbath is ordained by a precept of the decalogue. But a dispensation was granted in this precept; for it is written (1 Macc. 2:4): "And they determined in that day, saying: Whosoever shall come up to fight against us on the Sabbath-day, we will fight against him." Therefore the precepts of the decalogue are dispensable.
