Full Idea
There must be one supreme virtue essentially distinct from every other virtue, which directs all the virtues to the common good, and this virtue is legal justice.
Gist of Idea
Legal justice is supreme, because it directs the other virtues to the common good
Source
Thomas Aquinas (Summa Theologicae [1265], II-II Q58 6)
Book Reference

A Reaction
This concept of legal justice is underpinned, for Aquinas, by the concept of natural law, which has divine backing. Positive law could hardly fulfil such a major role, given that it could be corrupt.
