Cultivated and wild olives, and grafting (11:16–24)

Says “If the root is holy, so are the branches” (11:16, BSB). Some branches “have been broken off,” and the Gentile reader, “a wild olive shoot,” has been “grafted in among the others to share in the nourishment of the olive root” (11:17), so “do not boast over those branches” (11:18). If “you were cut from a wild olive tree, and contrary to nature were grafted into one that is cultivated,” the natural branches will much more readily be grafted back (11:24).

Sanday and Headlam (ICC, p. 328) hold that olive grafts must be branches from a cultivated olive set into a wild stock, “the reverse process being one which would be valueless and is never performed,” and that Paul’s argument depends on the process being unnatural. They call it beside the point to quote classical writers who may seem to support Paul’s language, since such passages would describe a process that can never actually be used. They also cite Origen, who says that farmers usually graft the olive onto the wild olive, not the wild olive onto the olive, and that Paul, by apostolic authority, reversed the order, fitting the things to the causes rather than the causes to the things.

Uncertain Whether 11:24 assumes a grafting practice known in Paul’s day or describes a deliberately unnatural one is an open question; no lean is taken here. This background does not decide who the root is or whom the warning of 11:22 addresses; the exegetical notes take those up.
