Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; Ye are no more strangers - In this chapter the Church of God is compared to a city, which, has a variety of privileges, rights, etc., founded on regular charters and grants. The Gentiles, having believed in Christ, are all incorporated with the believing Jews in this holy city. Formerly, when any of them came to Jerusalem, being ξενοι, strangers, they had no kind of rights whatever; nor could they, as mere heathens, settle among them. Again, if any of them, convinced of the errors of the Gentiles, acknowledged the God of Israel, but did not receive circumcision, he might dwell in the land, but he had no right to the blessings of the covenant; such might be called παροικοι, sojourners - persons who have no property in the land, and may only rent a house for the time being.
Fellow citizens with the saints - Called to the enjoyment of equal privileges with the Jews themselves, who, by profession, were a holy people; who were bound to be holy, and therefore are often called saints, or holy persons, when both their hearts and conduct were far from being right in the sight of God. But the saints spoken of here are the converted or Christianized Jews.
Of the household of God - The house of God is the temple; the temple was a type of the Christian Church; this is now become God's house; all genuine believers are considered as being οικειοι, domestics, of this house, the children and servants of God Almighty, having all equal rights, privileges, and advantages; as all, through one Spirit, by the sacred head of the family, had equal access to God, and each might receive as much grace and as much glory as his soul could possibly contain.
