How do we know that the truth of the gospel is more important than church leaders?

In his confrontation with Peter, Paul asserts the superiority of the truth of the gospel over the standing of prominent church leaders. He highlights that the gospel is ultimately about the person and work of Jesus Christ, and it must not be compromised for the sake of any individual, no matter how esteemed. Paul makes it clear that when Peter withdrew from fellowship with the Gentiles, he was not only acting hypocritically but also damaging the very essence of the gospel’s message of unity in Christ, which declares that in Christ, there is no Jew or Gentile. Thus, the truth of the gospel serves as a higher authority than even the revered figures within the church.
