Sorry for waiting so long to write back. It has been busy and this question can take a long answer. However, for the sake of getting back to you I am going to make it short.
The doctrine concerning the bride is found in the parables of Jesus Christ concerning His second coming to the nation of Israel (as in Matthew 25), as in the prophecy of Isaiah 61:10-11 and Isaiah 62:1-5, and the future fulfillment of Revelation 19:7-9 and Revelation 21:1-10. The Lord Jesus shall return and join Himself to (or marry) the nation of Israel. That is a future marriage in which the Lord Jesus shall be joined to the remnant who has kept themselves pure from the Anti-Christ. It is the time also in which Jesus Christ will join Himself to the land also, which shall then be called: “Beulah” (meaning: married) – Isaiah 62:4.
Paul never wrote to the Corinthians or anyone else telling them that they are “a virgin bride.” Paul never used the word “bride” in any of his epistles. That alone should inform us that we are not the bride of Christ.
Paul did however tell the Corinthians that he had “espoused” them “to one husband” (II Corinthians 11:2). Espoused: means joined. Notice it is past tense. It is already done! As in Ephesians 5:30-32 “For we are members of his body, of his flesh, and of his bones. For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church.” The great mystery is that we ARE bone of his bone and flesh of his flesh. We ARE one with Him. We ARE joined with Him. We ARE the Body of Christ!
So the “Body of Christ” (US) is not the future “Bride.” We are one with the Groom!
