Whether piety extends to particular human individuals?

Objections

Objection 1 : It seems that piety does not extend to particular human individuals. For Augustine says (De Civ. Dei x) that piety denotes, properly speaking, the worship of God, which the Greeks designate by the term {eusebeia}. But the worship of God does not denote relation to man, but only to God. Therefore piety does not extend definitely to certain human individuals.
Objection 2 : Further, Gregory says (Moral. i): "Piety, on her day, provides a banquet, because she fills the inmost recesses of the heart with works of mercy." Now the works of mercy are to be done to all, according to Augustine (De Doctr. Christ. i). Therefore piety does not extend definitely to certain special persons.
Objection 3 : Further, in human affairs there are many other mutual relations besides those of kindred and citizenship, as the Philosopher states (Ethic. viii, 11,12), and on each of them is founded a kind of friendship, which would seem to be the virtue of piety, according to a gloss on 2 Tim. 3:5, "Having an appearance indeed of piety [Douay: 'godliness']." Therefore piety extends not only to one's kindred and fellow-citizens.
