It is notable that the ESV and NRSV translate politeia as “commonwealth,” which in the first-century Greco-Roman context could mean a community of nations or ethnic groups sharing a common allegiance to a monarch. This sense of the term “commonwealth” fits the Ephesians 2 context well in my opinion since Gentiles are “fellow citizens” (sum-polites) with Jews in the politeia of Israel (Eph 2:12, 19).1 The sum- prefix emphasizes the historical context that Gentiles (i.e. members of nations and ethnic groups other than Israel) have joined themselves to a pre-existing Jewish theocratic entity, the nation of Israel, without becoming Jews (cf. Eph 3:6). Paul may be underscoring in Ephesians 2:12 this Jew-Gentile differentiation by using the nuanced term “politeia of Israel” instead of the name “Israel,” a term that he (and the rest of the Jewish world!) reserved for the Jewish people (cf. Rom 9-11; 1 Cor 10:18; 2 Cor 3:7, 13; Phil 3:5). Stated differently, the term “politeia of Israel” may refer to a multinational expansion of Israel proper that has emerged in the form of the Church.2 If this is the case, “commonwealth of Israel” is a particularly appropriate translation of “politeia of Israel” in Ephesians 2:12 and a relatively simple way of describing the relationship between the Church and Israel.
- This is the “one . . . out of two” mentioned in Ephesians 2:14-15. Markus Barth rightly calls into question the NRSV translation of Ephesians 2:15 (“one new humanity in place of the two”): “The new man is ‘one . . . out of the two’ . . . the new creation is not an annihilation or replacement of the first creation but the glorification of God’s work . . . this man consists of two, that is, of Jews and Gentiles . . . Their historic distinction remains true and recognized even within their communion” (Markus Barth, Ephesians: Introduction, Translation, and Commentary on Chapters 1-3 [Garden City: Doubleday, 1974], 309-10). Israel and the nations—the corporate representation of Jew and Gentile—become “one” (a composite unity) as husband and wife are “one” (Eph 5:31; Gen 2:24).
- Viewed in this way, the “commonwealth of Israel” (the Church) may be the unfolding of God’s promise to Israel in Genesis 35:11, “A nation and a company of nations shall come from you.”
