What then shall we say that Abraham, our earthly forefather, has gained?

For what says the Scripture? "And Abraham believed God, and this was placed to his credit as righteousness."

This declaration of blessedness, then, does it come simply to the circumcised, or to the uncircumcised as well? For Abraham's faith--so we affirm--was placed to his credit as righteousness.

and the forefather of the circumcised, namely of those who not merely are circumcised, but also walk in the steps of the faith which our forefather Abraham had while he was as yet uncircumcised.

Again, the promise that he should inherit the world did not come to Abraham or his posterity conditioned by Law, but by faith-righteousness.

so that the promise should be made sure to all Abraham's true descendants; not merely to those who are righteous through the Law, but to those who are righteous through a faith like that of Abraham. Thus in the sight of God in whom he believed, who gives life to the dead and makes reference to things that do not exist, as though they did, Abraham is the forefather of all of us. As it is written, "I have appointed you to be the forefather of many nations."

nor because they are Abraham's true children. But the promise was "Through Isaac shall your posterity be reckoned."

In other words, it is not the children by natural descent who count as God's children, but the children made such by the promise are regarded as Abraham's posterity.

I ask then, Has God cast off His People? No, indeed. Why, I myself am an Israelite, of the posterity of Abraham and of the tribe of Benjamin.
