ISB ~ 1 Corinthians 6 v11

such were some of you:Once prisoners in sin (6:910), the Corinthians have been redeemed and renewed by the washing of Baptism. The point is that God’s grace and forgiveness can rescue even the worst sinners from their deadly habits. washed . . . sanctified . . .

justified:Three effects of Baptism, through which sinners are cleansed of guilt (Acts 22:16), made holy (Rom 6:22), and adopted as heirs of eternal life (Tit 3:57). The added mention of Christ’s name and the work of the Spirit makes it certain that Paul is alluding to Baptism as the sacramental context for the Corinthians’ conversion (Acts 2:38; CCC 1227, 2813).
