There is one reference to "bride" in chapter 21, but it is referring to the new Jerusalem, which is not "the Church".
2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. (Revelation 21:2)
It is a simile, using "like" or "as". Whatever attributes the new Jerusalem possesses, it is adorned in a similar fashion. It doesn't say new Jerusalem is a bride. No where does it mention the "Church".
I guess we have a difference of opinion. Have a blessed day.
