Romans 2:28

28 After all, who is a real Jew, truly circumcised? It is not the man who is a Jew on the outside, whose circumcision is a physical thing.

Romans 2:28 Meaning and Commentary

Romans 2:28

For he is not a Jew which is one outwardly
The apostle removes the plea in favour of the Jews, taken from their name and privilege, by distinguishing between a Jew and a Jew, and between circumcision and circumcision: "he is not a Jew which is one outwardly"; by mere name, nature, nation, religion, and profession:

neither is that circumcision which is outward in the flesh;
which takes away the flesh of the foreskin, but not the carnality of the heart; leaves a mark upon the flesh, but no impression on the mind. This is nothing, is not the true, solid, substantial, spiritual circumcision, which only avails in the sight of God.

Romans 2:28 In-Context

26 If the Gentile, who is not circumcised, obeys the commands of the Law, will not God regard him as though he were circumcised?

27 And so you Jews will be condemned by the Gentiles because you break the Law, even though you have it written down and are circumcised; but they obey the Law, even though they are not physically circumcised.

28 After all, who is a real Jew, truly circumcised? It is not the man who is a Jew on the outside, whose circumcision is a physical thing.

29 Rather, the real Jew is the person who is a Jew on the inside, that is, whose heart has been circumcised, and this is the work of God's Spirit, not of the written Law. Such a person receives praise from God, not from human beings.
