Galatians 3:19

Analysis

Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator. Paul anticipates an objection: 'Wherefore then serveth the law?' (ti oun ho nomos, τί οὖν ὁ νόμος)—if the Law cannot justify or inherit, what's its purpose? The answer: 'It was added because of transgressions' (tōn parabaseōn charin prosetethē, τῶν παραβάσεων χάριν προσετέθη). The phrase 'because of' (charin, χάριν) is ambiguous: 'for the sake of' could mean

1. to reveal/increase transgressions (Romans 5:20, 7:7-13) or
2. to restrain transgressions (1 Timothy 1:9-10).

Both are true—the Law exposes sin and temporarily governs conduct.

The clause 'till the seed should come to whom the promise was made' (achris hou elthē to sperma hō epēngeltai, ἄχρις οὗ ἔλθῃ τὸ σπέρμα ᾧ ἐπήγγελται) reveals the Law's temporary nature. The conjunction achris hou (ἄχρις οὗ)—'until'—indicates the Law's time-limited function, ending when the Seed (Christ, v. 16) came. The promise was made to Christ; the Law was a temporary addendum until Christ arrived.

The phrase 'ordained by angels in the hand of a mediator' (diatageis di' angelōn en cheiri mesitou, διαταγεὶς δι' ἀγγέλων ἐν χειρὶ μεσίτου) indicates the Law's inferior mediation—given through angels (Acts 7:53, Hebrews 2:2) and a human mediator (Moses), unlike the Abrahamic promise spoken directly by God. The Law's indirect, temporary, inferior status contrasts with the promise's direct, permanent, superior status.

Historical Context

Jewish tradition (reflected in Deuteronomy 33:2 LXX, Jubilees, Josephus, Acts 7:53, Hebrews 2:2) held that angels mediated the Law at Sinai, with Moses as the human mediator between God and Israel. Paul uses this tradition to argue the Law's inferiority: the promise came directly from God to Abraham; the Law came indirectly through angelic and human mediation. The Law's purpose was temporary and preparatory—revealing sin and restraining evil until Christ came. Once Christ arrived, the Law's custodial function ended (v. 24-25).

Reflection

• How does the Law's purpose ('added because of transgressions') differ from justification? What does the Law reveal about sin and human inability?
• What is the significance of the Law being 'until the seed should come'? How does Christ's arrival fulfill and end the Law's custodial function?
• Why does Paul emphasize the Law's indirect mediation (angels, Moses) compared to the promise's direct communication from God? What does this reveal about their relative importance?
