Narcissus
Narcissus appears once, in Paul's roll of greetings at the end of Romans. The text greets not Narcissus himself but believers among his household.
A Greeting at Rome
The verse pairs Narcissus with Herodion in two adjacent greetings: "Greet Herodion my kinsman. Greet those of the [household] of Narcissus, who are in the Lord" (Ro 16:11). Paul singles out the members of his household who belong to the Lord, distinguishing them from any who do not.
