“Salute Herodion my kinsman. Greet them that be of the household of Narcissus, which are in the Lord.”
King James Version (KJV)
16:11 Those of the family of Aristobulus and Narcissus, who are in the Lord - It seems only part of their families were converted. Probably, some of them were not known to St. Paul by face, but only by character. Faith does not create moroseness, but courtesy, which even the gravity of an apostle did not hinder.
Ro 16:11 Of the [household] of Narcissus. At the time Paul wrote, a favorite of Nero, named Narcissus, was all powerful in Rome. He probably meant a number of his servants having accepted Christ.
