There is absolutely nothing in scripture to support such a theory.
Not in the sense these people are trying prove.
Though
In scripture Jesus came to redeem a "bride" for Himself.
But this is a spiritual sense.
The marriage supper is still future.
Rev. 19:7 Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife has made herself ready.
19:8 And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.
19:9 And he said unto me, Write, Blessed are they which are called unto the marriage supper of the Lamb. And he said unto me, These are the true sayings of God.
To the church it is given "that she should be arrayed in fine linen, clean and white," "not having spot, or wrinkle, or any such thing." Revelation 19:8; Ephesians 5:27.
"Christ honored the marriage relation by making it also a symbol of the union between Him and His redeemed ones. He Himself is the Bridegroom; the bride is the church, of which, as His chosen one, He says, "Thou art all fair, My love; there is no spot in thee." Song of Solomon 4:7. {AH 26.2}
"The church is the bride, the Lamb's wife. Every true believer is a part of the body of Christ. Christ regards unfaithfulness shown to Him by His people as the unfaithfulness of a wife to her husband. We are to remember that we are members of Christ's body (Letter 39, 1902).
"The Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely" (Revelation 22:17). The church is to say, Come. Every power in the church is to be actively engaged on the side of truth. The followers of Christ are to combine in a strong effort to call the attention of the world to the fast-fulfilling prophecies of the Word of God. {HP 328.2}
