On Justice and Temperance

St. Gregory the Dialogist ca. 540-604

[V]ery often justice, if it knows no bounds, falls into cruelty. Therefore, justice itself is truly justice which restrains itself with the rein of temperance in order that every man may also be temperate in the zeal with which he burns: lest if he be more zealous he lose justice, the bounds of which he ignores. (Homilies on the Book of Ezekiel, Homily 3.8)
