Context: The Greek term Ἰουδαϊκός (Ioudaïkós) appears in the New Testament to denote aspects related to Jewish identity, culture, or religion. This term is used to describe practices, beliefs, or characteristics that are distinctly Jewish. In the context of the early Christian church, the term often appears in discussions about the relationship between Jewish traditions and the emerging Christian faith.

In the New Testament, the use of Ἰουδαϊκός can be seen in discussions about the adherence to Jewish laws and customs by early Christians. The term highlights the cultural and religious background from which Christianity emerged and the ongoing dialogue about the role of Jewish law in the life of Christian believers.

For example, in Galatians 2:14, Paul addresses Peter's behavior concerning Jewish customs: "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, being a Jew, live like the Gentiles and not like the Jews, how can you compel the Gentiles to live like Jews?'" (BSB). Here, the term underscores the tension between Jewish customs and the new covenant in Christ.

The term Ἰουδαϊκός serves as a reminder of the Jewish roots of Christianity and the complex relationship between the two faiths. It reflects the historical context of the early church, where Jewish and Gentile believers navigated their shared faith in Christ while respecting their diverse cultural backgrounds.
