Ephesians 5:27

he--The oldest manuscripts and authorities read, "That He might Himself present unto Himself the Church glorious," namely, as a bride (Co2 11:2). Holiness and glory are inseparable. "Cleansing" is the necessary preliminary to both. Holiness is glory internal; glory is holiness shining forth outwardly. The laver of baptism is the vehicle, but the word is the nobler and true instrument of the cleansing [BENGEL]. It is Christ that prepares the Church with the necessary ornaments of grace, for presentation to Himself, as the Bridegroom at His coming again (Mat 25:1, &c.; Rev 19:7; Rev 21:2). not having spot-- (Sol 4:7). The visible Church now contains clean and unclean together, like Noah's ark; like the wedding room which contained some that had, and others that had not, the wedding garment (Mat 22:10-14; compare Ti2 2:20); or as the good and bad fish are taken in the same net because it cannot discern the bad from the good, the fishermen being unable to know what kind of fish the nets have taken under the waves. Still the Church is termed "holy" in the creed, in reference to her ideal and ultimate destination. When the Bridegroom comes, the bride shall be presented to Him wholly without spot, the evil being cut off from the body for ever (Mat 13:47-50).
