Sea Breeze, I believe in
"supplemental" theology in the sense that the Israel concept was
enlarged to include the nations, i.e., Christians. There is a debate as to what
the trunk symbolizes. Jesus is the root, as many scriptures indicate (cf. Is.
11:10; 53:2; Rom. 15:12; Rev. 5:5; 22:6; cf. Rom. 11:17, 18). The wild olive
branches would be the people of the nations, i.e., Christians. Natural
branches, to be grafted in again, would be the Jewish remnant.
Originally, Israel was
in a privileged position: "who, as such, are Israelites, to whom belong
the adoption as sons and the glory and the covenants and the giving of the Law
and the sacred service and the promises; to whom the forefathers belong and
from whom the Christ [sprang] according to the flesh" (Rom. 9:4, 5 NWT). Now
they must share these privileges with the people of the nations: "For
there is no distinction between Jew and Greek, for there is the same Lord over
all, who is rich to all those calling upon him." (Rom. 10:12 NWT)
Israel would have been
the premier nation if they stayed the course. Now only a remnant will be saved
(Rom. 10:22, 23; cf. Is. 10:22, 23). While Jesus was on earth, they claimed their
superiority because of being offspring of Abraham (Luke 8:39, 44). But Paul
explained Abraham was righteous, not because of circumcision, but because of
his faith (Gal. 3:6, 7). On this basis Christians also become “offspring” of Abraham, because
of their faith (3:8, 9, 29).
