How does the New Testament affirm the inclusion of Gentiles in the Church?

The inclusion of Gentiles within the Church is a major theme in the New Testament, signifying a radical shift in God's salvific plan. Scriptures such as Galatians 3:28 affirm that in Christ, there is neither Jew nor Gentile, for all are one in Him. The Apostle Paul, in his letters, frequently emphasizes that the Gospel is for all people, as seen in Romans 1:16, where he declares it is the power of God for salvation to everyone who believes. This radical inclusion embodies God's purpose for a diverse and multifaceted Church, reflecting His glory and mercy extended toward all nations, tribes, and tongues.
