For you are all sons of God through faith in Christ Jesus.  (27)For as many of you as were baptized into Christ have put on Christ.  (28)There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.  (29)And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.

The letter to the Galatians was written by the Apostle Paul and may be the earliest letter written by Paul.  He had spent some time with the Galatians and preached the gospel of faith in Jesus Christ which makes us right with God.  Justification and salvation follow.  After Paul had moved on certain men came out of Jerusalem ( legalizers) who  told the Galatians it was necessary to embrace the ceremonial aspects of Judaism – circumcision and acceptance of the law to be assured of salvation.  The letter to the Galatians is occasioned by this threat to gospel preached by Paul.

The promise of salvation was made by God to Abraham before the law was given to Moses 430 years later.  The law did not abrogate the Promise.  Christ, the  Messiah, was promised as Abraham’s seed.  The law was given to teach the Jews that sinfulness could not be defeated by works.  No man could keep the law.  Jesus is the Messiah and the end of the law.  Belief and faith in Jesus Christ is the path to salvation.  Faith in Jesus makes ALL who believe, heirs to the promise given by God to Abraham  – all, Jews or Gentiles, are on a level; all alike are children of God in the same manner and on the same terms that Abraham was.

Paul states a position unique in Christianity that all are sinners; all are on a level; all are saved in the same way and all are entitled to the same privileges as children of God.  This does not mean that ability or distinctions are ignored – it does not mean that all are on a level with talents, comforts or wealth.  It means that all are on a level with regard to salvation.  This is what Paul is discussing in these verses.  He is not trying to break down distinctions in society.  All are on a level before God.  All are equally accepted through faith in Jesus Christ.
