Romans 4:1
1What then will we say that Abraham, our forefather, has found according to the flesh?
What then will we say that Abraham, our forefather, has found according to the flesh? Paul does not disown Abraham; he asks whether flesh—descent, circumcision, works—explains the father’s standing. The next word will send us to Genesis 15:6, not to the family tree.
Arminian readers find a sincere appeal to Israel’s father. If Abraham himself did not gain righteousness by the flesh, neither do his children. The question is pastoral: stop measuring gain by blood and start listening to Scripture.
Calvin already hears the trap: if Abraham was justified because he embraced mercy by faith, he had nothing to glory in. “According to the flesh” names the boast that would rest on lineage or works. Paul will not let the patriarch become a wage-earner at God’s bar.
The apostle is dismantling glorying before he quotes Moses. Abraham’s gain is not in the flesh. The courtroom is God’s; the next verses will prove that the father’s righteousness was imputed, not achieved.
