I’m going to be working on a little informal piece on filial piety. Good thing to keep in mind when speaking of justice:
“Just as it belongs to religion [the greatest of moral virtues and the highest form of justice] to give worship to God, so does it belong to piety, in the second place, to give worship to one's parents and one's country.” (Aquinas, ST II-II, q. 101, a. 1).
