Praescriptio (1:1-5): 

    Superscriptio (1:1-2a) 
      1Paul an apostle -- sent neither by human commission nor from human authorities, but through Jesus Christ and God the Father, who raised him from the dead -- 2and all the members of God's family who are with me
    Adscriptio (1:2b): 
      To the churches of Galatia: 
    Salutatio (1:3-5): 
      3Grace to you and peace from God our Father and the Lord Jesus Christ, 4who gave himself for our sins to set us free from the present evil age, according to the will of our God and Father, 5to whom be the glory forever and ever. Amen. 
Proem [Exordium] (1:6-10): 
         6I am astonished that you are so quickly deserting the one who called you in the grace of Christ and are turning to a different gospel -- 7not that there is another gospel, but there are some who are confusing you and want to pervert the gospel of Christ. 8But even if we or an angel from heaven should proclaim to you a gospel contrary to what we proclaimed to you, let that one be accursed! 9As we have said before, so now I repeat, if anyone proclaims to you a gospel contrary to what you received, let that one be accursed! 
         10Am I now seeking human approval, or God's approval? Or am I trying to please people? If I were still pleasing people, I would not be a servant of Christ. 
Body (1:11-6:10): 
    Basic Divisions (by chapters): 
      I. (1-2) Paul's defense of his apostleship 
      II. (3-4) Paul's defense of his Gospel message 
      III. (5-6) Implications of the Gospel for daily living 
    Designated Text (5:13-24): 
           13For you were called to freedom, brothers and sisters; only do not use your freedom as an opportunity for self-indulgence, but through love become slaves to one another.** 14For the whole law is summed up in a single commandment, "You shall love your neighbor as yourself." 15If, however, you bite and devour one another, take care that you are not consumed by one another. 
           16Live by the Spirit, I say, and do not gratify the desires of the flesh. 17For what the flesh desires is opposed to each other, to prevent you from doing what you want. 18But if you are led by the Spirit, you are not subject to the law. 19Now the works of the flesh are obvious: fornication, impurity, licentiousness, 20idolatry, sorcery, enmities, strife, jealousy, anger, quarrels, dissensions, factions, 21envy, drunkenness, carousing, and things like these. I am warning you, as I warned you before: those who do such things will not inherit the kingdom of God.
           22By contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness, 23gentleness, and self-control. There is no law against such things. 24And those who belong to Christ Jesus have crucified the flesh with its passions and desires. 

Conclusio (6:11-18): 
         11See what large letter I make when I am writing in my own hand! 12It is those who want to make a good showing in the flesh that try to compel you to be circumcised -- only that they may not be persecuted for the cross of Christ. 13Even the circumcised to not themselves obey the law, but they want you to be circumcised so that they may boast about your flesh. 14May I never boast of anything except the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. 15For neither circumcision nor uncircumcision is anything; but a new creation is everything! 16As for those who will follow this rule -- peace be upon them, and mercy, and upon the Israel of God. 
         17From now on, let no one make trouble for me; for I carry the marks of Jesus branded on my body. 
         18May the grace of our Lord Jesus Christ be with your spirit, brothers and sisters. Amen.

 **Compare this foundational statement to the first expression of it in 5:1. 
"For freedom Christ has set us free. Stand firm, therefore, and do not submit again to a yoke of slavery.

     Also note the third expression of this foundational principle in 5:25. 
"If we live by the Spirit, let us also be guided by the Spirit.

     In the paranetical section (5:1-6:10), the principle of freedom leading to the Holy Spirit's guidance is stated as a foundation principle for each of the three subsections: 5:1,2-12; 5:13,14-24; 5:25,26-6:10. Each section advances the issue from freedom from legalism (5:1-12), to genuine servanthood through the Holy Spirit (5:13-24), to how the Spirit's help is implemented in interpersonal relations and self-awareness (5:25-6:10). This section (5:1-6:10) answers the Judaizers charge that a gospel of grace leads to an immoral lifestyle, and constitutes Paul's third argument in the body of the letter.
