Yes I believe that The Church is the Bride of Christ. Here is Matthew Henry’s Commentary.
His repeated commendation of the beauty of the spouse (Song of Solomon 4:7): Thou art all fair, my love. He had said (Song of Solomon 4:1), Thou art fair; but here he goes further, and, in review of the particulars, as of those of the creation, he pronounces all very good: “Thou art all fair, my love; thou art all over beautiful, and there is nothing amiss in thee, and thou hast all beauties in thee; thou art sanctified wholly in every part; all things have become new (2 Corinthians 5:17); there is not only a new face and a new name, but a new man, a new nature; there is no spot in thee, as far as thou art renewed.” The spiritual sacrifices must be without blemish. There is no spot but such as is often the spot of God’s children, none of the leopard’s spots. The church, when Christ shall present it to himself a glorious church, will be altogether without spot or wrinkle, Ephesians 5:27. God bless you dear one!!! :):)
