Romans 3:1
Romans 3:11What, then, is the advantage of being a Jew? Or what is the value of circumcision?
Watchtower commentary takes as Paul's transition question after his prosecution of Jewish hypocrisy in chapter 2. "What, then, is the advantage of the Jew?" is read as affirming the Jewish covenantal heritage while preparing to show that even the Jew stands under the same judgment. The Watchtower applies the principle to itself: covenantal identity (Jewish then, JW now) is no insulation from obedience requirements.
is the diatribe pivot. Paul has just argued that Jewish identity does not exempt anyone from judgment (2:1-29). His imagined interlocutor objects: "If circumcision is no advantage, what is left for the Jew?" Paul's answer threads through 3:1-9 and lands at v9: "Jews as well as Greeks are all under sin." The answer is: Jewish heritage was a real advantage (entrusted with God's word, v2), but it does not produce justification. Universal need (3:9-20), universal rescue (3:21-26). The Watchtower applies "covenantal identity is no insulation" to the wrong target — first-century Judaism, not the JW organisation — but the principle Paul establishes cuts both ways: organisational membership in the right community is not a substitute for justifying faith in Christ.
