By the beginning of the 1st century ce, piety/godliness (Greek: εὐσέβεια; Latin: pietas) came to entail the dutiful fulfilment of one’s obligations to one’s household, homeland, and gods. It could also describe one’s respectful attitude toward and treatment of the dead, guests, hosts, and supplicants as well as describe keeping an oath. Numerous studies on the use of piety in the New Testament have been concerned about identifying the cultural backgrounds that influenced the biblical authors’ deployment of the term and whether such use retains its Greek and Roman meanings, derives from Hellenistic Judaism, or reflects a “Christianization” of the term to encapsulate the complete Christian life, including both proper belief and practice. Outside of the field of biblical studies, philologists in classics have studied the evolution and use of the term εὐσέβεια and its cognates in ancient Greek literature, where the term had significant purchase in philosophical literature. The Latin virtue of pietas gains significant prominence in political discourse near the dusk of the Roman Republic and at the dawn of the Roman Empire with the publication of Virgil’s Aeneid and Augustus’s restoration of priesthoods and temples. Although the term εὐσέβεια and its cognates occur in Acts and 2 Peter, the majority of attention to the significance of this term in early Christian literature has centered around its meaning and function in the canonical Letters to Timothy and Titus, also known as the Pastoral Epistles. In particular, scholars have been concerned about whether the use of the term in the Pastorals reflects the respective author’s accommodation to Greek society (and thus a further development away from the earliest/more authentic/Pauline articulations of the Christian faith) or rather reflects enculturation within Hellenistic Jewish thought. Neither the historical Jesus nor Paul in his undisputed letters describe the ideal Christian life in terms of piety—thus it remains a fascinating topic to consider the social and political implications of early Christians utilizing this terminology which held significant cultural capital and prestige in its Greek and Roman cultural contexts.
