Galatians says those who belong to Christ are heirs according to promise; Titus says those justified by grace become heirs according to the hope of eternal life. The technical inheritance vocabulary is the bridge: belonging to Christ and justification by grace both culminate in heirship grounded in divine promise/hope.

Galatians 3:28 and Colossians 3:11 both describe identity in Christ as more fundamental than ethnic and social status. Galatians names Jew/Greek and slave/free; Colossians likewise relativizes Greek/Jew and slave/free because Christ is all and in all.

Galatians declares slave and free one in Christ; 1 Timothy’s “they are brethren” applies that new identity inside an existing master-servant relation without claiming the social institution has vanished.

Both passages unite Jew and Greek and bond and free within a baptismal/Spirit-created identity in Christ.

Galatians 3:26–29 and Colossians 3:9–11 use closely related identity formulas in which ethnic, circumcision, and social distinctions no longer determine standing in Christ’s renewed people. Both passages center belonging in Christ rather than inherited boundary markers.

Ephesians develops the Jew-Gentile unity announced in Galatians by describing both groups as one new humanity and one household through Christ.

Genesis 17 joins covenant, Abraham’s seed, and inheritance; Galatians 3 says those who belong to Christ are Abraham’s seed and heirs according to promise. Paul develops Abrahamic inheritance around union with Christ while also transforming the role of circumcision.

Deuteronomy declares that YHWH shows no partiality, while Galatians announces a shared standing in Christ across Jew and Greek, slave and free, male and female. The link concerns divine impartiality, not identical covenant settings.
