King James Bible
"For as many of you as have been baptized into Christ have put on Christ."
Paul addresses believers who have undergone baptism as a public identification with Christ's death and resurrection. The phrase 'into Christ' suggests immersion into a new sphere of existence—union with Christ himself. This baptismal language counters the Judaizers' emphasis on circumcision as the entry rite into God's people. Like putting on clothing, believers have 'clothed' themselves with Christ's character and status. In the Greco-Roman world, clothing signified social identity and position. This metaphor emphasizes that Christians now bear Christ's identity, making ethnic and social distinctions (which Paul addresses in verse 28) irrelevant for standing before God.
