Very good. We are not replacements for Israel, in spite of the nuts and crazies and lunatics that accuse us of claiming that. We have been offered the New Covenant and for that we are eternally grateful. But we do not supplant Israel and we are adopted sons, not the original sons.
I've been curious about this statement, annalex. I'm not sure what you mean by this. Please explain further.
St. Paul speaks in stronger terms, speaking of "grafting" replacing the old branches broken off. Further, the genetic Israel itself is broken off and in need of re-grafting:
[16] For if the firstfruit be holy, so is the lump also: and if the root be holy, so are the branches. [17] And if some of the branches be broken, and thou, being a wild olive, art ingrafted in them, and art made partaker of the root, and of the fatness of the olive tree, [18] Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee. [19] Thou wilt say then: The branches were broken off, that I might be grafted in. [20] Well: because of unbelief they were broken off. But thou standest by faith: be not highminded, but fear.When a branch is broken off and another grafted in, that is replacement, even though every connotation that the Replacement theology has accrued may not be there. To wit, the genetical Israel is prophesied to be regrafted in a more natural way.[21] For if God hath not spared the natural branches, fear lest perhaps he also spare not thee. [22] See then the goodness and the severity of God: towards them indeed that are fallen, the severity; but towards thee, the goodness of God, if thou abide in goodness, otherwise thou also shalt be cut off. [23] And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again. [24] For if thou wert cut out of the wild olive tree, which is natural to thee; and, contrary to nature, were grafted into the good olive tree; how much more shall they that are the natural branches, be grafted into their own olive tree?
(Romans 11)
