Paul applied the bride metaphor to the church as well:
Husbands, love your wives, just as Christ also loved the church and gave Himself up for her, so that He might sanctify her, having cleansed her by the washing of water with the word, that He might present to Himself the church in all her glory, having no spot or wrinkle or any such thing; but that she would be holy and blameless.
For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. This is a great mystery, but I speak concerning Christ and the church.
2 Corinthians 11:2
For I have betrothed you to one husband, that I may present you as a chaste virgin to Christ.
