Are there any precepts that relate to the virtue of justice and the virtues thereto annexed together with the gift of piety which crowns them?
Yes; they are the precepts of the Decalogue (CXXII. 1).
Do the precepts of the Decalogue relate only to these virtues?
Yes; for those precepts which relate to other virtues are of later origin and are determinations or unfoldings of the former precepts (CXXII. 1).
Why is this so?
This is so because the precepts of the Decalogue, in so far as they are the first precepts of the moral law, should refer to what for all and at first sight manifestly has the nature of a thing that is due; and further, this perception of a thing as due should include relations towards others such as the virtue of justice with its virtues annexed demand (ibid.).
