That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
Read Chapter 5
Augustine of Hippo
AD 430
By the same bath of regeneration and water of sanctification all sins of the redeemed are cleansed and healed, not only those which are pardoned at this time in baptism but also those that are subsequently contracted by human infirmity or ignorance.
What Christ is accomplishing [in baptism] is that the church should be “holy and spotless.” It is “holy” in that it has been cleansed by the washing of water by the Word. It is “spotless” in that it is without spot or wrinkle. .
Not having spot or wrinkle. St. Augustine and others expound it of the glorious Church of Christ, in heaven: others even of the Church of Christ in this world, as to its doctrine, sacraments, and discipline, or practices approved by the Catholic Church. (Witham)
By the washing or laver He washes her uncleanness. By the word, says he. What word? In the Name of the Father, and of the Son, and of the Holy Ghost. Matthew 28:19 And not simply has He adorned her, but has made her glorious, not having spot, or wrinkle, or any such thing. Let us then also seek after this beauty ourselves, and we shall be able to create it. Seek not thou at your wife's hand, things which she is not able to possess. Do you see that the Church had all things at her Lord's hands? By Him was made glorious, by Him was made pure, by Him made without blemish? Turn not your back on your wife because of her deformity.

Thou reproachest not her, but Him that made her; what can the woman do? Praise her not for her beauty. Praise and hatred and love based on personal beauty belong to unchastened souls.

By what “word is she washed”? “In the name of the Father, and of the Son and of the Holy Spirit.” He did not simply bathe her; he adorned her, making her glorious, having no spot or wrinkle or anything lacking. Let us too seek that sort of beauty, and grace will make us able to refract it. The husband does not seek from the wife something she does not have to give. For you see the pattern: the church has received everything from Christ. .
For this Church is the daughter of the Highest, which has been in travail of you by the word of grace, and has "formed Christ in you "of whom you are made partakers, and thereby become His holy and chosen members, "not having spot or wrinkle, or any such thing; but as being holy and unspotted in the faith, ye are complete in Him, after the image of God that created you."
