How did St. Paul describe the relationship between Jewish and Gentile Christians?

St. Paul the Apostle described the relationship between Jewish and Gentile Christians as one of fundamental equality, rooted in the belief that both groups are justified by faith in Christ rather than by adherence to the Jewish law.12

Paul argued that because both Jews and Gentiles have fallen short of the glory of God, they are equally in need of salvation, which is made available to both through faith in Jesus. He maintained that Gentile converts did not need to become Jewish—by accepting circumcision or observing specific food laws—to participate in the people of God.213

In his view, the coming of Christ rendered the law obsolete as a requirement for righteousness, effectively breaking down the partitions between groups. Paul famously articulated this unity in his letter to the Galatians, stating that "there is no longer Jew or Greek... for all of you are one [person] in Christ Jesus". He envisioned the church as a single body of Christ, where members are transformed and united, transcending traditional social and religious distinctions.4215
