Yes, the ekklesia appears in the OT (LXX) and NT, and yes, there has always been one people of God by faith, but that truth does not support your system — because the OT ekklesia was the assembly of Old‑Covenant Israel under Torah, while the NT ekklesia is the New‑Covenant Church (Jew + Gentile) in Christ, and Scripture explicitly distinguishes these two covenant communities rather than merging them: the OT assembly was a national, ethnic, covenant‑bound people (Exod 19; Deut 4), while the NT assembly is a transnational, Spirit‑born people (Eph 2:14–16; Gal 3:28), and the NT repeatedly says the Old Covenant is obsolete and vanished (Heb 8:13), the law‑nation is no longer the covenant people (Rom 10:4), and the Church is the new humanity created in Christ (Eph 2:15). So yes, there is one people of God by faith — but that one people is not “the modern nation of Israel,” and it is not “the biblical nation of Israel continued,” it is the New‑Covenant ekklesia formed by Christ, into which ethnic Israel will be grafted again by faith (Rom 11:23–27), not by pilgrimage, geography, or national sorting. Your claim that Malachi and Joel describe two Israels being sorted by a Jerusalem prayer‑call collapses because the prophets speak of the wicked vs. the righteous, not “modern Israel vs. biblical Israel,” and the NT defines the one people of God as those in Christ, not those in a political state
