1 Corinthians 6:11

ye are washed--The Greek middle voice expresses, "Ye have had yourselves washed." This washing implies the admission to the benefits of Christ's salvation generally; of which the parts are; (1) Sanctification, or the setting apart from the world, and adoption into the Church: so "sanctified" is used Co1 7:14; Joh 17:19. Compare Pe1 1:2, where it rather seems to mean the setting apart of one as consecrated by the Spirit in the eternal purpose God. (2) Justification from condemnation through the righteousness of God in Christ by faith (Rom 1:17). So PARÆUS. The order of sanctification before justification shows that it must be so taken, and not in the sense of progressive sanctification. "Washed" precedes both, and so must refer to the Christian's outward new birth of water, the sign of the inward setting apart to the Lord by the inspiration of the Spirit as the seed of new life (Joh 3:5; Eph 5:26; Tit 3:5; Heb 10:22). Paul (compare the Church of England Baptismal Service), in charity, and faith in the ideal of the Church, presumes that baptism realizes its original design, and that those outwardly baptized inwardly enter into vital communion with Christ (Gal 3:27). He presents the grand ideal which those alone realized in whom the inward and the outward baptism coalesced.
