Whether observance is a greater virtue than piety?

Objections

Objection 1 : It seems that observance is a greater virtue than piety. For the prince to whom worship is paid by observance is compared to a father who is worshiped by piety, as a universal to a particular governor; because the household which a father governs is part of the state which is governed by the prince. Now a universal power is greater, and inferiors are more subject thereto. Therefore observance is a greater virtue than piety.
Objection 2 : Further, persons in positions of dignity take care of the common good. Now our kindred pertain to the private good, which we ought to set aside for the common good: wherefore it is praiseworthy to expose oneself to the danger of death for the sake of the common good. Therefore observance, whereby worship is paid to persons in positions of dignity, is a greater virtue than piety, which pays worship to one's kindred.
Objection 3 : Further honor and reverence are due to the virtuous in the first place after God. Now honor and reverence are paid to the virtuous by the virtue of observance, as stated above (Article [1], ad 3). Therefore observance takes the first place after religion.
