Galatians 3

Paul argues that justification is received solely through faith in Jesus Christ, contrasting this with the impossibility of being justified by the works of the Law. He demonstrates through the Abrahamic covenant that the promise of blessing preceded the Law and is fulfilled only in Christ, the promised Seed.

• Paul rebukes the Galatians for abandoning the clear gospel of Christ for the works of the Law.
• Paul appeals to the example of Abraham to prove that faith, not works, is the basis of righteousness.
• Paul argues that the Law brings a curse, from which Christ redeemed his people by becoming a curse himself.
• Paul defines the Law as a temporary guardian ('schoolmaster') that served to restrain and reveal sin until the coming of the promised Seed, Christ.
• Paul concludes by affirming that believers are now children of God, united in Christ and heirs according to the promise, regardless of social or ethnic distinction.

• Abraham (justified by faith)
• The curse (Deuteronomy 21:23)
• The Promise (given to the Seed, Christ)
• The Schoolmaster (paidagōgos, the custodian/tutor)
• 430 years (the interval between the promise to Abraham and the Law)

This chapter establishes the definitive relationship between the Law and the Gospel, asserting that the Law cannot save but was a divine tutor leading humanity to its need for Christ.

Justification before God is attained exclusively through faith in Jesus Christ, just as it was for Abraham, liberating believers from the curse of the Law.

The chapter flows from a sharp personal rebuke of the Galatians' spiritual inconsistency to a dense, legal, and historical defense of justification by faith, culminating in a declaration of the believer's new identity in Christ.

• In thee shall all nations be blessed (Galatians 3:8)
• We might receive the promise of the Spirit through faith (Galatians 3:14)
• If ye be Christ's, then are ye Abraham's seed, and heirs according to the promise (Galatians 3:29)

• Know ye therefore that they which are of faith, the same are the children of Abraham (Galatians 3:7)

• Cursed is every one that continueth not in all things which are written in the book of the law to do them (Galatians 3:10)
• If the inheritance be of the law, it is no more of promise (Galatians 3:18)

• The Galatian churches were being infiltrated by 'Judaizers' who taught that Gentile converts must be circumcised and follow the Mosaic Law to be truly righteous.
• The 'schoolmaster' (paidagōgos) in the Roman world was a household slave charged with guarding a child and escorting him to his tutor, a role Paul uses to illustrate the Law's limited, non-saving function.

• Paul's argument regarding inheritance and testaments (v15-17) reflects the Greco-Roman understanding that a man's confirmed will or covenant could not be changed.

• Chapter 3 shifts from the personal narrative of Chapter 2 (the confrontation at Antioch) to a formal, rigorous theological proof of the gospel.

• Paul links the Abrahamic covenant (Genesis 12, 15) with the Mosaic covenant to show that the later Law cannot void the earlier Promise. Matthew Henry observes that the heavy sufferings of the Son of God, who was made a curse for us, more loudly warn sinners to flee from the wrath to come than all the curses of the law.

• Genesis 15:6: 'accounted to him for righteousness' (v6)
• Genesis 12:3: 'In thee shall all nations be blessed' (v8)
• Deuteronomy 27:26: 'Cursed is every one that continueth not...' (v10)
• Habakkuk 2:4: 'The just shall live by faith' (v11)
• Deuteronomy 21:23: 'Cursed is every one that hangeth on a tree' (v13)

• 'Foolish' (ἀνόητος [G453]) carries the sense of acting without perception or thought.
• 'Bewitched' (βασκαίνω [G940]) refers to malignant fascination, often implying a spell or evil eye.
• 'Schoolmaster' (paidagōgos) is not a teacher, but a custodian or guardian slave who supervised children.

• Paul's careful use of the singular 'Seed' (sperma) in v16 to argue that the covenant promise was specifically directed at Christ, rather than Abraham's descendants in general.

• There is ongoing historical debate concerning whether 'the curse of the law' refers exclusively to the failure to keep the Mosaic ceremonial statutes or the universal moral failure of mankind. Interpretive traditions differ between those who view the Law as a covenant of works (Reformed/Covenantal) and those who emphasize the Law's function as a national boundary marker (New Perspective on Paul).
