So then (αρα ουν). Two inferential particles (accordingly therefore).

No more (ουκετ). No longer.

Sojourners (παροικο). Old word for dweller by (near by, but not in). So Acts 7:6; Acts 7:29; 1. Peter 2:11 (only other N.T. examples). Dwellers just outside the house or family of God.

Fellow-citizens (συνπολιτα, old, but rare word, here only in N.T.), members now of the πολιτεια of Israel (verse Ephesians 2:12), the opposite of ξενο κα παροικο.

Of the household of God (οικειο του θεου). Old word from οικος (house, household), but in N.T. only here, Galatians 6:10; 1. Timothy 5:8. Gentiles now in the family of God (Romans 8:29).
