Gentiles Grafted into Israel and Made Jewish Theologically
Paul's metaphor of Gentiles being grafted into Israel (Romans 11:17-24) describes a theological transformation in which non-Jews enter the covenant people of God through faith in Christ. The apostle depicts Israel as a cultivated olive tree, with some natural branches broken off due to unbelief, and wild olive branches—Gentiles—grafted in contrary to nature [4]. This imagery conveys that Gentiles do not replace Israel but are incorporated into the existing root and structure of God's covenant people.
Biblical Foundation and Early Practice
The term "Gentiles" (nations) designated all peoples outside Israel, those "aliens from the worship, rites and privileges of Israel" [1]. Before Christ, Gentiles could join Israel's covenant community as proselytes, "foreigners who adopted the Jewish religion," with varying degrees of adherence to Jewish law and practice [2]. The New Testament extends this pattern dramatically: Gentiles now receive full covenant membership through faith in the Jewish Messiah, without requiring circumcision or full Torah observance.
Paul's argument in Romans 11 emphasizes both continuity and transformation. Gentiles become partakers of Israel's "spiritual things"—the promises, the covenants, the messianic hope [8]. They are no longer "strangers" but fellow heirs, grafted into the same olive tree that sustained Abraham, Moses, and David [3, 7]. This incorporation is theological rather than ethnic: Gentiles remain Gentiles by birth but are joined to Israel's covenant identity through union with Christ.
Patristic and Reformed Interpretation
Early Christian interpreters understood this grafting as the fulfillment of prophetic expectation. Augustine described the apostolic mission as Israel "passing over into Babylon by Christ and the Apostles," bringing Gentiles into the covenant community [5]. The pattern was established in Christ's own ministry: initially sent "only to the lost sheep of the house of Israel," he later commissioned the apostles to all nations after his resurrection [6].
The grafting metaphor preserves Israel's priority while affirming Gentile inclusion. As one commentator notes, Gentiles "by nature were sinners of the Gentiles, children of wrath," bearing no covenant fruit until grafted in [4]. The wild olive receives life from the cultivated root, not vice versa. This theological incorporation means Gentiles share in Israel's inheritance—the kingdom, the Spirit, the resurrection hope—while Israel's own restoration remains part of God's unfinished purpose (Romans 11:25-26).

The word was used contemptuously by them. In the New Testament it is used as equivalent to Greek. This use of the word seems to have arisen from the almost universal adaption of the Greek language.”
