Thayer's Greek Lexicon STRONGS NT 2452: ἸουδαϊκῶςἸουδαϊκῶς, adverb, Jewishly, after the manner of the Jews: Galatians 2:14. ((Josephus, b. j. 6, 1, 3.)) Topical Lexicon Biblical Occurrence Galatians 2:14 records the single New Testament appearance of the adverb Ἰουδαϊκῶς: “When I saw that they were not walking in line with the truth of the gospel, I said to Cephas in front of them all, ‘If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?’” Historical Setting • Location: Syrian Antioch, a mixed congregation where Jewish and Gentile believers regularly shared table fellowship (Acts 11:19–26). Paul’s Use of the Term • Contrast of Lifestyles: Paul juxtaposes Peter’s earlier freedom (“live like a Gentile”) with his present retreat to a distinctly Jewish mode of life (“live like a Jew”). Jew–Gentile Relations in the Early Church • Table Fellowship: Shared meals symbolized spiritual equality (Acts 10:28; 11:3). Reintroducing ritual separation threatened gospel-centered unity. Theological Significance • Justification: Galatians 2:16 insists, “A man is not justified by works of the law, but by faith in Jesus Christ.” The adverb marks the law-keeping lifestyle that cannot justify. Practical Ministry Implications • Consistency with the Gospel: Leaders must ensure that personal choices—dietary, cultural, or otherwise—do not imply a two-tiered church. Related Biblical Themes • “Living under the Law” versus “walking by the Spirit” (Galatians 5:16–18). Strong’s Greek 2452 therefore serves as a linguistic pivot in Galatians, spotlighting the early church’s defining struggle over the place of Jewish customs in the multi-ethnic body of Christ and affirming the unchanging gospel of grace for every believer.
