Romans 2:25

2:25 For circumcision ¹  has its value if you practice the law, but ²  if you break the law, ³  your circumcision has become uncircumcision.

Romans 3:20

3:20 For no one is declared righteous before him ⁴  by the works of the law, ⁵  for through the law comes ⁶  the knowledge of sin.

[2:25]  ¹ sn Circumcision refers to male circumcision as prescribed in the OT, which was given as a covenant to Abraham in Gen 17:10-14. Its importance for Judaism can hardly be overstated: According to J. D. G. Dunn (Romans [WBC], 1:120) it was the “single clearest distinguishing feature of the covenant people.” J. Marcus has suggested that the terms used for circumcision (περιτομή, peritomh) and uncircumcision (ἀκροβυστία, akrobustia) were probably derogatory slogans used by Jews and Gentiles to describe their opponents (“The Circumcision and the Uncircumcision in Rome,” NTS 35 [1989]: 77-80).

[2:25]  ² tn This contrast is clearer and stronger in Greek than can be easily expressed in English.

[2:25]  ³ tn Grk “if you should be a transgressor of the law.”

[3:20]  ⁴ sn An allusion to Ps 143:2.

[3:20]  ⁵ tn Grk “because by the works of the law no flesh is justified before him.” Some recent scholars have understood the phrase ἒργα νόμου (erga nomou, “works of the law”) to refer not to obedience to the Mosaic law generally, but specifically to portions of the law that pertain to things like circumcision and dietary laws which set the Jewish people apart from the other nations (e.g., J. D. G. Dunn, Romans [WBC], 1:155). Other interpreters, like C. E. B. Cranfield (“‘The Works of the Law’ in the Epistle to the Romans,” JSNT 43 [1991]: 89-101) reject this narrow interpretation for a number of reasons, among which the most important are: (1) The second half of v. 20, “for through the law comes the knowledge of sin,” is hard to explain if the phrase “works of the law” is understood in a restricted sense; (2) the plural phrase “works of the law” would have to be understood in a different sense from the singular phrase “the work of the law” in 2:15; (3) similar phrases involving the law in Romans (2:13, 14; 2:25, 26, 27; 7:25; 8:4; and 13:8) which are naturally related to the phrase “works of the law” cannot be taken to refer to circumcision (in fact, in 2:25 circumcision is explicitly contrasted with keeping the law). Those interpreters who reject the “narrow” interpretation of “works of the law” understand the phrase to refer to obedience to the Mosaic law in general.

[3:20]  ⁶ tn Grk “is.”
