Whether piety is a special virtue distinct from other virtues?

Objections

Objection 1 : It seems that piety is not a special virtue distinct from other virtues. For the giving of service and homage to anyone proceeds from love. But it belongs to piety. Therefore piety is not a distinct virtue from charity.
Objection 2 : Further, it is proper to religion to give worship to God. But piety also gives worship to God, according to Augustine (De Civ. Dei x). Therefore piety is not distinct from religion.
Objection 3 : Further, piety, whereby we give our country worship and duty, seems to be the same as legal justice, which looks to the common good. But legal justice is a general virtue, according to the Philosopher (Ethic. v, 1,2). Therefore piety is not a special virtue.
