Εὐσέβεια

[Meaning] a knowledge of the service of a god.¹ Therefore excellent people, in being pure, are fitting to offer sacrifice to a god; for they avoid the sins concerning a god, and god is delighted with them; for they are both pious and just. They are priests as well; for they carefully consider what is related to sacrifices, foundations,² purifications, and the other matters appropriate to the divine.
"Piety is an easy thing and quite full of temperance and in no way burdensome."³
"For piety does [not] expire with mortals; whether they live, whether they die, it is not destroyed."⁴
