Romans 11:16

And if the firstfruit is holy, so is the lump: and if the root is holy, so are the branches. [Another parallelism. The apostle demonstrates the same truth, first, from the standpoint of the law of God in the Bible (firstfruit and lump); second, from the law of God in nature (root and tree). As the harvest or raw material of the Jew was regarded as unclean, or ceremonially unholy, and not to be eaten till it was cleansed by the waving of a first-portion, or firstfruit, of it as a heave-offering before the Lord (Leviticus 23:9-14; Exodus 34:26); so the meal or prepared material was likewise prescribed until a portion of the first dough was offered as a heave-offering. This offered "firstfruit," or, better, "first-portion" (aparche), made the whole lump (phurama) from which it was taken holy, and thus sanctified all the future meal, of which it was the representative or symbol, so that it could now be used by the owner (Numbers 15:19-21; Nehemiah 10:37). The apostle, then, means that as the patriarchs, Abraham, Isaac and Jacob (called fathers in verse 28), the firstfruit by the revealed law, and the root by the natural law, were holy, so all their descendants as lump and tree were likewise holy. But holiness has two distinct meanings: (1) Purity, moral and spiritual perfection, absolute righteousness--a holiness unto salvation; (2) that which is consecrated or set apart for divine use--a holiness short of salvation. The second meaning is the one intended here. The Jews, being out of Christ, are certainly not holy or righteous unto salvation, Paul being witness; but they have what Gifford styles "this legal and relative holiness of that which has been consecrated to God." In this respect they are still "the holy people" (Daniel 12:7), "the chosen people" (Daniel 11:15), preserved from fusion with the Gentiles, and ultimately to be restored to their original pre-eminence as leaders in the worship of Jehovah. In short, then, there is no divinely erected barrier rendering them irrevocably unholy, and preventing their conversion. On the contrary, they are pre-eminently susceptible to conversion both by law divine and natural, and only their persistent unbelief prevents their Christianization.]
