Well, Paul DOES say that there is ONLY one body. I believe it is that ONE body that is being spoken about when "resurrection" of the "dead in Christ" is talked about. It is that "body" that will rise...not a physical "body".
Romans 12:5
so in Christ we who are many form
one body, and each member belongs to all the others.
1 Corinthians 12:12
The body is a unit, though it is made up of many parts; and though all its parts are many, they form
one body. So it is with Christ.
1 Corinthians 12:20
As it is, there are many parts, but
one body.
Ephesians 2:16
and in this
one body to reconcile both of them to God through the cross, by which he put to death their hostility.
Ephesians 3:6
This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of
one body, and sharers together in the promise in Christ Jesus.
Ephesians 4:4
There is
one body and one Spiritjust as you were called to one hope when you were called
Ephesians 4:25
Therefore each of you must put off falsehood and speak truthfully to his neighbor, for we are all members of
one body.
Colossians 3:15
Let the peace of Christ rule in your hearts, since as members of
one body you were called to peace. And be thankful.
It is the dead "body" of sin that has to be resurrected:
Romans 6:6
For we know that our old self was crucified with him so that the
body of sin might be done away with, that we should no longer be slaves to sin
We know our physical "body" isn't done away with when we are saved
Romans 8:10
But if Christ is in you,
your body is dead because of sin, yet your spirit is alive because of righteousness.
Is your PHYSICAL "body" dead because of your sin?
1 Corinthians 15:35
[
The Resurrection Body ] But someone may ask, "How are the dead raised? With what kind of
body will they come?"
Notice Paul says "body" and not "bodies" ONE body.
1 Corinthians 15:42
So will it be with the resurrection of the dead. The
body that is sown is perishable, it is raised imperishable.
Notice again the singular "body" and not "bodies".
1 Corinthians 15:44
it is sown a natural
body, it is raised a spiritual
body.If there is a natural
body, there is also a spiritual
body.
Again, Paul continues to use the singular "body" and not "bodies". He doesn't say "there are natural BODIES and there are also spiritual BODIES"
2 Corinthians 4:10
We always carry around in
our body the death of Jesus, so that the life of Jesus may also be revealed in
our body.
Paul says " OUR body"....why doesn't he say "OUR BODIES"...he's obviously talking about many people by using "OUR"....but he STILL uses the singular "BODY" and not "bodies". OUR ONE BODY.
2 Corinthians 4:11
For we who are alive are always being given over to death for Jesus' sake, so that his life may be revealed in
our mortal body.
Again, Paul says OUR mortal BODY (singular)...why not "bodies".
Then notice Paul's usage of of the term "body" when he's referring to his OWN PERSONAL PHYSICAL BODY as opposed to this OTHER "body" he's been talking about:
THE "body"
Philippians 1:24
but it is more necessary for you that I remain
in THE body.
His PERSONAL body
Galatians 6:17
Finally, let no one cause me trouble, for I bear on
MY body the marks of Jesus.
Philippians 1:20
I eagerly expect and hope that I will in no way be ashamed, but will have sufficient courage so that now as always Christ will be exalted
in MY body, whether by life or by death.
Paul referring to his listeners PHYSICAL "body" or "bodies"
1 Thessalonians 4:4
that each of you should learn to control
his OWN body in a way that is holy and honorable.
Romans 7:5
For when we were controlled by the sinful nature, the sinful passions aroused by the law were at work in
OUR bodies,(notice the plural) so that we bore fruit for death.
And we see in this next verse that Paul used the term "body" to refer to a GROUP of people
1 Timothy 4:14
Do not neglect your gift, which was given you through a prophetic message when the
body of elders laid their hands on you.
What do you think Peter means here by "judged according to men in regard to THE BODY"?
1 Peter 4:6
For this is the reason the gospel was preached even to those who are now dead, so that they might be
judged according to men in regard to the body, but live according to God in regard to the spirit.
Then let's look at the 3 scriptures where Paul talks about "bodies" where people say it is referring to the "resurrection"
Romans 8:11
And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal
bodies through his Spirit, who lives in you.
No mention of resurrection here. Paul is talking to his listeners about something that had already happened to them "if the spirit is living in you".
Romans 8:23
Not only so, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption as sons, the redemption of our
bodies.
Paul said this was something THEY were eagerly awaiting....and equates the "redemption of our bodies" with " our adoption as sons". We know this happened in 70AD when Jesus returned. That is when the "adoption" occurred and therefore that is ALSO when the "redemption of our bodies" occurred. THere is no resurrection mentioned here.
Philippians 3:21
who, by the power that enables him to bring everything under his control, will transform our lowly
bodies so that they will be like his glorious body.
Again, no mention of "resurrection" here. It's talking about "transformation" of their lowly bodies to be like Jesus "glorious BODY". Why doesn't Paul say " will RESURRECT our lowly bodies "? We've already seen over and over and over how Paul referred to Jesus' "BODY".....and it was NEVER in reference to His physical body....but always in reference to His SPIRITUAL body..or the "body" of believers. At Jesus return He was going to "transform" (not resurrect) the believer's "lowly bodies" into the true "body of Christ"......making them ALL into ONE eternally.
1 Corinthians 12:27
Now you ARE the body of Christ, and each one of you is a part of it.
Romans 12:5
so in Christ
we who are many form one body, and each member belongs to all the others
Ephesians 4:25
Therefore each of you must put off falsehood and speak truthfully to his neighbor,
for we are all members of one body.
