Romans 2:23-27

You who boast in the Law, through your breaking the Law, do you dishonor God?

For “the name of God is blasphemed among the Gentiles because of you,” just as it is written.

For indeed circumcision is of value if you practice the Law; but if you are a violator of the Law, your circumcision has turned into uncircumcision.

So if the uncircumcised man keeps the requirements of the Law, will his uncircumcision not be regarded as circumcision?

And he who is physically uncircumcised, if he keeps the Law, will he not judge you who though having the letter of the Law and circumcision are a violator of the Law?
