Romans 2:24-26

New Revised Standard Version, Anglicised

²⁴ For, as it is written, ‘The name of God is blasphemed among the Gentiles because of you.’

²⁵ Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision has become uncircumcision. ²⁶ So, if those who are uncircumcised keep the requirements of the law, will not their uncircumcision be regarded as circumcision?
