Which concept signifies duty to the gods, family, and state in Roman thought?

• A. Arete
• B. Pietas
• C. Nostos
• D. Xenia

Answer: (B)

Pietas is the Roman virtue of dutiful respect and obligation to the gods, to family, and to the state. It isn’t just religious reverence; it covers performing the proper rites for the gods, honoring ancestors, caring for parents, and fulfilling one’s duties to Rome—even when it requires personal sacrifice. In Roman storytelling, Aeneas embodies pietas by obeying the gods’ commands, supporting his family, and pursuing the founding of a lineage that will become Rome, all at significant personal cost.

Arete is a general Greek idea of virtue or excellence; Nostos refers to the homeward journey or return, a concept from epic traditions; Xenia is the guest–host code of hospitality. None of these tie together the religious, familial, and civic obligations the way pietas does, which is why it’s the best fit for the described concept.
