Isaiah 54:5
Your Maker is your husband— the Lord Almighty is his name.
Isaiah 62:3-5
You will be a crown of splendor in the Lord's hand, a royal diadem in the hand of your God. No longer will they call you Deserted, or name your land Desolate. But you will be called Hephzibah, and your land Beulah [which means married], for the Lord will take delight in you, and your land will be married. As a young man marries a maiden, so will your sons marry you; as a bridegroom rejoices over his bride, so will your God rejoice over you.
Hosea 2:19-20, God speaking to his people:
I will betroth you to me forever; I will betroth you in righteousness and justice, in love and compassion. I will betroth you in faithfulness, and you will acknowledge the Lord.
Jesus speaks of himself as the bridegroom.
Mark 2:18-20
Some people came and asked Jesus, "How is it that John's disciples and the disciples of the Pharisees are fasting, but yours are not?" Jesus answered, "How can the guests of the bridegroom fast while he is with them? They cannot, so long as they have him with them. But the time will come when the bridegroom will be taken from them, and on that day they will fast."
John the Baptist spoke of Jesus as the bridegroom.
John 3:28-30
"You yourselves can testify that I said, 'I am not the Christ but am sent ahead of him.' The bride belongs to the bridegroom. The friend who attends the bridegroom waits and listens for him, and is full of joy when he hears the bridegroom's voice. That joy is mine, and is now complete. He [Jesus] must become greater; I must become less."
The church is betrothed, espoused and promised as the intended bride of her husband, Jesus Christ. The marriage is not consummated. That is yet to come.
2 Corinthians 11:2
I am jealous for you with a godly jealousy. I promised you to one husband, to Christ, so that I might present you as a pure virgin to him.
At the end, we see the bride married to Jesus.
Revelation. 19:6-8
"Hallelujah! For our Lord God Almighty reigns. Let us rejoice and be glad and give him glory! For the wedding of the Lamb has come, and his bride has made herself ready. Fine linen, bright and clean, was given her to wear." (Fine linen stands for the righteous acts of the saints.)
Revelation 21:2,9-11
I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband.... One of the seven angels... said to me, "Come, I will show you the bride, the wife of the Lamb." And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God. It shone with the glory of God.
And yet, none of the parables Christ gave about the Marriage Supper and Wedding used the idea of the bride as Christ's Church.
