Context: "For all of you who were baptized into Christ have clothed yourselves with Christ" (Galatians 3:27). The verse grounds (γάρ, "for") the preceding declaration that "you are all sons of God through faith in Christ Jesus" (3:26) and feeds the conclusion that in Christ "there is neither Jew nor Greek, slave nor free, male nor female" (3:28), so that believers are "Abraham's seed and heirs according to the promise" (3:29). Paul is arguing against the Judaizers that covenant identity comes by faith-union with Christ, not by law-keeping: the law was a guardian until faith came (3:23-25). Within that argument, v. 27 supplies the decisive image — baptism marks incorporation into Christ, and that incorporation is described as being clothed (ἐνεδύσασθε) with Christ Himself. The metaphor likely evokes the early baptismal practice of re-robing, but its theological freight is older: in Scripture, clothing given from outside confers identity, status, and acceptability. To "put on Christ" is to have one's standing before God constituted entirely by Him — His sonship, His righteousness — which is precisely why all ethnic, social, and gender distinctions cease to define covenant membership (v. 28).
Greek Key Terms:
OT-to-OT Development (OT background): The clothing-grammar Paul deploys was built across the canon. God Himself clothed the naked and ashamed in Genesis 3:21 — covering as divine gift, not human achievement. The vestment-institution of Exodus 28:2 made clothing the bearer of priestly identity and acceptability. Psalm 132:9, 16 internalized the vestments — priests clothed with righteousness and salvation (Psalm 132:9) — and Isaiah 61:10 cast the same triad as Messianic gift: "He has clothed me with garments of salvation." Zechariah 3:4-5 supplied the dramatic form — filthy garments removed, pure vestments conferred by divine initiative alone (Zechariah 3:4). Galatians 3:27 announces that this whole development has reached its object: the clothing God always promised to provide is Christ Himself.
Connections:
Christological Connection: In its own context the verse teaches that covenant standing is worn, not woven: the baptized do not assemble a righteousness out of works of law but receive an identity from outside themselves, by incorporation into another. Paul's logic is participatory — sons of God (v. 26) because clothed with the Son (v. 27); Abraham's seed (v. 29) because united to the Seed (v. 16). The clothing image carries the entire anti-legalist argument: what you wear is what God sees, and what the believer wears is Christ.
This is the already-pole of the garment trajectory's fulfillment. Aaron's vestments conferred a representative, external, removable glory on one man, once a year, before God; Christ confers Himself on all His people, permanently, as their standing before God. The escalation runs along every axis the institution established: from garments about holiness to the Holy One Himself as garment; from one high priest clothed on behalf of twelve tribes to every member of the people — Jew or Greek, slave or free, male or female — personally vested; from fabric that was stripped off each evening (Lev 16:23) to a union nothing can dissolve. The Great Exchange stands beneath the metaphor: He was stripped (Matt 27:28, 35) that we might be clothed; He who knew no sin was made sin "so that in Him we might become the righteousness of God" (2 Cor 5:21).
Already/not-yet: Galatians 3:27 is emphatically already — aorist indicative, an accomplished vesting at union with Christ. The same union generates the imperative ("clothe yourselves with the Lord Jesus Christ," Romans 13:14; Colossians 3:12) — live out what you wear — and awaits its public consummation when the Bride is arrayed in fine linen, bright and pure (Rev 19:8). What is now true by faith will then be true by sight.
Connection Method(s): Promise-Fulfillment (primary) — the verse announces the performance of the OT's verbalized clothing-promises (Ps 132:16 "I will clothe her priests with salvation"; Isa 61:10), now realized in union with Christ; the NT text is itself the fulfillment-pole, so the relation is promise reaching performance rather than type meeting antitype. Also Typology (as the antitype's application) — within TT 073 this verse is where the institutional type (Ex 28's external, representative vesting) is answered and surpassed: correspondence (identity conferred by God-given clothing), historicity (real institution, real baptism), escalation (one priest/fabric/removable → all believers/Christ Himself/permanent), pointing-forwardness (Ex 28's borrowed holiness and Ezra 2:63's suspended institution), retrospective interpretation (Paul's ἐνδύω consciously inhabits the LXX vesting vocabulary). Also Corporate Solidarity as the operative principle: the many wear the One, and so become in Him the priestly people the garments prefigured (1 Pet 2:9).

This Foundation Text treats v. 27 specifically under the vestment angle — clothed with Christ as the fulfillment of the priestly garment-institution.
