It has been a while since I studied this but as I recall a “bride” of Christ in only mentioned twice in the NT and both times it refers to the New Jerusalem.
The Church as the Bride in Ephesians 5:22-33:
The Church is called the Bride of Christ and Christ is declared the Head of the Church, His Bride.
From the NIV TRANSLATION : 👇👇
22 Wives, submit yourselves to your own husbands as you do to the Lord. 23 For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior. 24 Now as the church submits to Christ, so also wives should submit to their husbands in everything.
25 Husbands, love your wives, just as Christ loved the church and gave himself up for her 26 to make her holy, cleansing[a] her by the washing with water through the word, 27 and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. 28 In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. 29 After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— 30 for we are members of his body. 31 “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.”[b] 32 This is a profound mystery—but I am talking about Christ and the church. 33 However, each one of you also must love his wife as he loves himself, and the wife must respect her husband.
Also in Isaiah 54:5 ( Old Testament ), the Husband and Wife metaphor is used for Israel :
For your Maker is your husband, the Lord of hosts is his name; and the Holy One of Israel is your Redeemer, the God of the whole earth he is called
Also, In the Gospel of John, John the Baptist speaks of Jesus Christ as the bridegroom and mentions the bride.
He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom’s voice: thus my joy therefore is fulfilled.[John 3:29 ]
In the Gospels, when Jesus is asked why his disciples do not fast, but the followers of John the Baptist and the Pharisees do, Jesus answers with this metaphor:
And Jesus said unto them, Can the friends of the bridegroom fast, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast.[Mark 2:19]
True, but Christ is elsewhere referred as a "Bridegroom," such as in John 3:29, Matthew 9:15; Mark 2:19-20; Luke 5:34-35) and it is implied in Matthew 25:1-13.
