MNT(i)
17 Now if you bear the name of a Jew, and rely upon law, and boast yourself in God,
18 and know his will, and can test the things that differ; if you are instructed out of the Law,
19 and are confident that you yourself are a darkness,
20 an instructor of the foolish, a teacher of the young, because you have in the Law the form of knowledge and of the truth—well then, you who are teaching others, do you ever teach yourself?
21 You who are preaching that a man should not steal, do you practise theft?
22 You who keep saying that a man should not commit adultery, do you commit adultery? You who hold idols in abhorrence, are you plundering their temples?
23 You who are making your boast in the Law, do you habitually dishonor God through your transgressions of the Law?
24 For the name of God is continually blasphemed among the Gentiles because of you, even as the Scripture itself says.
25 Circumcision does indeed profit, if you are obedient to the Law; but if you habitually break the Law, your circumcision is become uncircumcision.
26 So if the uncircumcised keeps the ordinance of the Law, shall not his uncircumcision be reckoned equivalent to circumcision.
27 And shall not those who are physically uncircumcised, but who keep the Law, condemn you who are a breaker of the Law, although you have a written law and circumcision?
28 For the real Jew is not the man who is one outwardly, and the real circumcision is not outward in the flesh;
29 but the real Jew is one inwardly, and real circumcision is heart—circumcision, spiritual, not literal, praised not by men, but by God.
