They have been made partakers with those who were near to God, becoming fellow citizens of the sons of God." The Apostle uses three comparisons to explain how near they have become. They have become near as citizens are near to one another and to their prince.
They are near as members of one household are near to one another and to its head. They are near as parts of a building are near to each other and to the one who dwells in it. These comparisons correspond to the earlier stages of estrangement from God and from His people (12).
"There he says, ‘strangers from the covenants of promise,’ and ‘alienated from the commonwealth of Israel.’ Here, against the first, he says, ‘you are no longer strangers and sojourners.’ Against the second, he says, ‘but fellow citizens with the saints and members of the household of God’" (blessed Jerome).
You were like foreigners living far away in other places. Or, though living there, you did not possess the right of citizenship, being παροικοι, residents, temporary and accidental dwellers. Now you have become fellow citizens, συμπολιται. "Now you have the same city as the saints, the heavenly Jerusalem" (Oecumenius).
"You have been enrolled in the same city, which exists in heaven and abides forever, and which they also ardently desired" (Theophylact). "Do you see? We have been enrolled and made fellow citizens, not simply of the Jews, but of men great in holiness, such as Abraham, Moses, and Elijah.
See into what city we have been enrolled. See where we shall one day appear" (Saint Chrysostom). The gracious Kingdom of Christ was depicted as a city "whose builder and maker is God" (Heb 11:10).
The Old Testament saints knew that they were citizens foreordained for this city. Yet they did not see the city itself, but ardently desired to see it and greeted it from afar. In this respect they too were strangers and sojourners, seeking their own city and fatherland, as they themselves confessed (Heb 11:13).
From this Saint Chrysostom draws the following conclusion: "Those who say such things, that is, who called themselves strangers and sojourners, show that they seek a fatherland (Heb 11:14). But you are already fellow citizens of the saints, and not strangers and sojourners."
"You have been counted worthy of very high dignity by becoming fellow citizens with the saints" (Theodoret). Fellow citizens with the saints means members of one gracious kingdom, all of whom are holy. Indeed, they are members because they are holy.
Here one must understand not only those who came after Christ, but also those who came before Christ, for both are in Christ. The Kingdom of God is the Kingdom of all ages. As the saints of old were holy by faith in the coming Christ, so the new saints are holy by the same faith in Christ who has come.
This faith united them both with Christ and with one another. Believers have one Master, and wherever they live, they are all fellow citizens. Those who wished to acquire Roman citizenship made a payment and bought it. In the gracious Kingdom of Christ, men bring faith in the Lord and are numbered among His fellow citizens (Ambrosiaster).
The Apostle’s second comparison, explaining the nearness into which the Ephesians and all the Gentiles have come by grace, is taken from the closeness of members of one family. "Members of the household of God" means God’s own. This is still nearer.
Fellow citizens are of one spirit and share one love for their fatherland, but they are not children of one father. In a family all are kin and relations. So too all believers have one Father, God. They have been begotten "not of corruptible seed but of incorruptible, through the word of the living God which abides forever" (1 Pet 1:23).
Whatever tribe a man may belong to, grace makes all God’s own. Thus by faith in the Lord, those who receive Him receive the power to become children of God. They are not merely reckoned among children, but truly are children, being born of God.
Therefore they are God’s own, and they bear this kinship in the feeling of the heart, as the reflection of all that grace accomplishes in them. God’s own! What a lofty title. What a consoling and sweet side of Christianity.
This is not a dream of self-deception, but the very essence of the matter. One must note that, although in comparison, conceptually, citizenship and kinship can be distinguished as degrees of nearness, in the gracious kingdom the two converge in reality.
Spiritual citizenship comes from unity of spirit. This unity is produced by the same Spirit through whom all receive the same birth. Through Him they are placed into kinship with one another and with God. All fellow citizens of Christ’s Kingdom are also kinsmen. Such they hold themselves to be in heart and in mutual relations.
