What would compel one Apostle to publicly oppose and rebuke another Apostle? Doesn't that kind of confrontational activity and spirit hinder our missionary efforts and tarnish the church's reputation? Paul doesn't think so. Faithful servants of Jesus Christ must be diligent to build walls and bridges and to correct those who build them in the wrong places. This famous confrontation serves as a teaching moment for the church, showing us what's needed if we're going to have a healthy gospel culture that bears witness to the truth of the gospel.
