YES that is exactly what I am saying.
Who do you think the captives were that were set free by Jesus after He died on the cross?
They were saved Old Testament Saints, not Church age saints.
You say there is only one body, which is correct, but then you refer to another body which is merely a "friend" of the bride?
That is not a 'body' it is a group of other believers.
Only the church is ever called a Body in the Bible and that is the mystery revealed to Paul (Eph.3)
Saved Jews of the Old Testament (and Tribulation) are friends of the bride, not the bride.(Jn.3:29) Actually, you have mis-quoted John 3:29. Here, followers of John the baptist approach him with concerns that he is being upstaged by Jesus. John's response was that he (John) is a "friend of the BrideGROOM" John is referring to himself... not others. Friends of the Bridegroom is another reference to believers.
The verse states that he that hath the bride is the Bridegroom, but the friend of the bridegroom which standeth and heareth, rejoiceth greatly because of the bridegroom's voice this my joy therefore is fulfilled.
Now, what John the Baptist is saying is that he is neither the Bridegroom (Christ) nor the Bride since he is a friend of the Bridegroom and thus cannot be the Bride.
Who is the Bride, the Church (Eph.5).
John the Baptist is a saved Old Testament saint and not part of the church, but is a friend of the Bridegroom.
By the way... what is your denomination?
