Thematic Bible: Whose circumcision is made uncircumcision

For circumcision indeed profits, if you do the law: but if you be a transgressor of the law, your circumcision has become uncircumcision. Then if uncircumcision may keep the righteousness of the law, will not his uncircumcision be counted for circumcision? and that which is uncircumcision by nature, perfecting the law, will judge you, who through the letter and circumcision are a transgressor of the law.
