Final answer:
In Christian theology, God, through Christ, removed barriers, creating a unified people, with salvation accessible to all, exceeding the traditional Jewish messianic expectations of a political liberator.
Step-by-step explanation:
In the person and work of Christ, God has broken down the barrier between Jew and Gentile and is creating for himself one renewed people in Christ Jesus, saved by grace through faith. The liberation that Jesus offered, as understood by early Christians, was a spiritual one, surpassing the physical and political expectations of the messianic ideal within Jewish doctrine. Jesus' characterization as the Messiah expanded the scope beyond just the liberation of Jews, to the idea of a universal salvation accessible to all, and this perspective was heavily influenced by the efforts of St. Paul. Furthermore, the distinct social inclusiveness of early Christian teachings, the idea that all human beings are spiritually equal with no consideration of social class, was contrary to the Roman hierarchical norms and signaled a significant shift towards universalism within the Christian faith.
