5. The Unity of all believers Vv. 26-29
Because Paul was addressing all the differences the Galatians were hearing from the Judaizers, Paul spoke to the ONENESS in Christ. Those in Christ are the sons and daughters of God. Because of that (being the sons of God) you who have been baptized into Christ are one together and are clothed in Christ.
Baptism demonstrated their faith—people “believed and were baptized”—not the other way around. It also demonstrated identification with the body of believers, the Christian church.
Paul may have been referring to the baptism of the Holy Spirit. When a person believes, the Holy Spirit comes to dwell within. Jesus promised this (John 14:16-17). The Holy Spirit also supernaturally makes us a part of the body of Christ (1 Corinthians 12:12-13). (Life Application New Testament Commentary.)
Verse 28 speaks of one of the most important parts of what Christianity is all about. There are no racial, social or ethnic barriers when one becomes a Christian. When you are a part of Christ nothing else matters, you are first of all a Christ follower. In the days of Paul, Jews and Gentiles (Greek) were never mixed as far as the Jews were concerned. In the Roman society there were great divisions as well. But when a Jew, a Roman or a Greek became a Christian, then all separatism was destroyed. A new believer was a Christian before all else. It was something that had to be learned and as one matured one understood the family of God. Sometimes we might also have problems with other races, or ethnic or social groups. If we could just see each other as God sees us, in Christ, then we would never have those prejudices that come to us through our old way of believing or thinking. Today, God is calling us to see all people as one in Christ no matter the color of our skin or the look of our face or where we came from, we are the ones who can break down those differences by allowing Christ to live freely and fully in us.
Social barriers were broken down as people became Christians. There were many people who were slaves that became Christians and they were considered the same before Christ as someone who was a free person. (See the book of Philemon regarding the way Paul handle a slave becoming a Christian and how the master and slave were to relate to one another.) Such distinctions were important to break down if the church of Jesus Christ was to be one body.
When you are introduced to someone else wouldn’t it be great to say that you are a believer or a Christian who happens to be a … Christian lawyer or Christian doctor or Christian teacher, etc... We have created barriers for our lives too and if we would but be identified as a believer rather than by our occupation first then some of those barriers would fall.
As for the distinctions of male or female, Paul said that they were the same in Christ. Men and women are not the same but in Christ there is no difference, one is not more important than the other for we are all “one” in Christ.
Paul who preached that all are one in Christ also taught about the different roles of men and women in the church of Jesus Christ but clearly said that before the Lord there is not difference in importance or privilege. The social, racial and ethnic difference were extremely important to the Romans and Jews as well as others throughout the civilized land, but in Christ all that was changed. All these barriers were broken down. All are one in Christ! All are equally valuable to God. Differences arise in gifts, in function, in abilities, but all are one in Christ (Ephesians 2:15).
Paul then, at the end of this discourse brings us back to the beginning and says that all who belong to Christ are Abraham’s seed and therefore are heirs to the promise given to Abraham. The promise to be loved of God and found faithful and righteous in Christ through our faith. The grace of God is given to us through faith in the death, burial and resurrection of the Son of God. I am a child of God with heaven as my home!
