And so all Israel shall be saved: as it is written,
There shall come out of Zion the Deliverer, and shall turn away ungodliness from Jacob:
Read Chapter 11
Ambrosiaster
AD 400
God will give them back the free exercise of their will so that, because their unbelief did not spring from malice but from error, they may be put right and afterward be saved…. Paul quotes Isaiah in order to prove that God has reserved a gift for them, in order to teach that they can be set free by the same grace by which the believing Jews have already been set free, because he is not empty but always full of grace. Commentary on Paul’s Epistles.
Not all the Jews were blind; some of them recognized Christ. But the fullness of the Gentiles comes in among those who have been called according to the plan, and there arises a truer Israel of God … the elect from both the Jews and the Gentiles.
Although it was rejected, Israel will also be saved eventually, a hope which Paul confirms by quoting this text of Scripture. For indeed, Israel will be saved in its own time and will be called at the end, after the calling of the Gentiles. .
What does it mean to say that “all Israel will be saved?” Just as we say that the whole world and all the nations are being saved because everywhere and among all nations there are those who are coming to faith, so also “all Israel will be saved” does not mean that every one of them will be but that either those who were understood by Elijah or those who are scattered all over the world will one day come to faith. .
