Yes, the Colossians were primarily Gentiles. The city of Colossae, located in what is now western Turkey, was part of the Roman province of Phrygia. During the time the Apostle Paul wrote his letter to the Colossians, the majority of the inhabitants were not of Jewish descent. Instead, they were non-Jewish people who practiced various pagan religions and cultural influences.
This is reflected in Paul’s letter to the Colossians where he addresses them as a community that was once alienated from the promises made to Israel. In his writing, he emphasizes the transformation they undergo through faith in Christ, highlighting their inclusion into the body of believers, which was originally composed of Jews.
Furthermore, the message of the Gospel that Paul preached aimed at reaching all people, breaking the barriers between Jews and Gentiles. The Colossians’ Gentile identity serves to illustrate the broader theme of the early church’s mission to include all nations in the Christian faith.
