Thematic Bible: Whose circumcision is made uncircumcision

For circumcision indeed is profitable if you perform the law, but if you are a transgressor of the law, your circumcision becomes uncircumcision. If therefore the uncircumcision keeps the ordinances of the law, shall not its uncircumcision be accounted for circumcision? And the uncircumcision by nature which keeps the law shall judge you who with the written law and circumcision are a transgressor of the law.
