ISB ~ Revelation 19 v7 - 9
Christ and the Church are forever united in a covenant of marital love. In one sense, this is a present reality for the Church, who is joined to the Bridegroom by the grace of Baptism (Eph 5:22-32); but it is also a future hope, inasmuch as that union will reach perfection in the glory of heaven (Mt 25:1-13). John envisions the Church dressed in a bridal gown sewn by a life of purity and righteousness. Later, the Bride of the Lamb is described as the heavenly Jerusalem, the virgin city gilded with gold and adorned with precious stones (21:9-21) (CCC 757, 865).
• The marriage of the bridal city recalls Ezek 16:8-14, where the Lord joined himself in wedlock to ancient Jerusalem, having cleansed her in water and clothed her in gold, jewelry, and fine linen. Similar images of glorified Zion appear in Is 61:10 and 62:5.
