What does Galatians 3:28 mean?
Paul has been making the case to the Gentile (non-Jewish) Christians in Galatia that they don't need to listen to the Judaizers. They don't need to follow the law in order to be saved (Galatians 2:4). By faith in Christ, and by faith alone, they are already full children of God Almighty (Galatians 3:7–9). They have been baptized into God's Spirit (who is in them). They have put on Christ like a robe and are covered by Him. What would they gain by trying to follow the law again?Now Paul assures these believers that, in Christ, they have been fully united with everyone else who is in Christ. There are no lesser Christians in the family of God. Our earthly identifiers create no value distinction between us in our Father's eyes. Jews do not carry a higher rank than Greeks (non-Jews). Free people hold no greater honor than slaves. Men are not superior to women. No race is a "master race," nor any ethnicity inferior.
How is this possible? Christ holds the most honored position in the family of God, and all Christians are "in Christ." In that way, we are one, we are united. Since none can be higher and none can be lower, we are equal in the eyes of God.
It's important to note that this teaching is not based on the current climate of the culture. It is not liberal, conservative, or political. It is the direct result of the gospel. It is not a statement about the various roles any Christian may be called to fill in this life or the honor we may or may not be given on this side of eternity. It is a statement about our equal value in the eyes of God, and how we should learn to view each other. Since all Christians are in Christ, all of us are one.
