Colossians 4:15

Nymphas (Numpan). That is masculine, if autou (his) is genuine (D E K L) after kat oikon, but Numpa (feminine) if auth (her) is read (B 67). Aleph A C P read autwn (their), perhaps including adelpou (brethren) and so locating this church (ekklhsia) in Laodicea. It was not till the third century that separate buildings were used for church worship. See Romans 16:5 for Prisca and Aquila. It is not possible to tell whether it is "her" or "his" house here.
