Reply Obj. 2: The precepts of the decalogue held the first place in the moral order, as stated above (Q. 100, A. 3): and consequently it is fitting that other moral precepts should be distinguished in relation to them. But the judicial and ceremonial precepts have a different binding force, derived, not from natural reason, but from their institution alone. Hence there is a distinct reason for distinguishing them.
Reply Obj. 3: The Law alludes to the division of the judicial precepts in the very things themselves which are prescribed by the judicial precepts of the Law. ________________________
