What motivated the Corinthian “wise” to participate in cultic acts involving idol-food (1 Corinthians 8, 10)? Viewing the wise through an Epicurean lens fruitfully highlights their possible motives and theology. Previous comparison has misunderstood Epicurean perspectives on cultic participation. Some view participation in traditional cult as “religiously insignificant” for Epicureans (see Graham Tomlin, “Christians and Epicureans in 1 Corinthians” in JSNT 68, 1997). Through an examination of Philodemus’ work On Piety, this paper will argue that participation in wider society’s cultic acts was not an adiaphoron for Epicureans, but a constitutive part of Epicurean piety. For Philodemus, Epicureans participated because (1) it maintained natural social customs and laws, (2) it enabled Epicureans to account for non-Epicurean cult within their own system, (3) it formed their understanding of the gods, and (4) it was pleasurable. This paper will utilize this model to explore the motivations and theology of the Corinthian wise.
