I believe that, in your zeal to get to to the crux (as you see it) you make hasty comments. Are you really sure about your last statement? And to call it "false" (with all that word implies)? Are you thus lumping scholars like Hodge with the JWs? He certainly (to name one of many) believed in spiritual resurrection as well as physical. A quick check found also writings by Ryle and Vos along the same lines.
I must say I was surprised that you had written that.
In my study of the resurrection I have come to the conclusion that the resurrection can refer only to the body. That is what makes the J.W. position so ridiculous. It is a non-resurrection.
Here is the definition of death:
James 2:26 For
as the body without the spirit is dead, so faith without works is dead also.
--The spirit is separated from the body at death. It either goes to heaven or hell. Is the term "resurrection" ever applied to this situation? Not that I know of. It only applies to the body. This is why we are able to attack the RCC doctrine of Mariolatry effectively. Mary is dead. She is still in the grave, along with everyone else who has died. We don't pray to the dead. Mary, along with all the apostles, and other saints of God that have died, are awaiting a physical resurrection, where their bodies will be raised from the dust of this earth. Their spirits may already be in heaven. But someday they will be united together again as one person.
1 John 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
--Some of those that John wrote to probably saw the resurrected Lord. Now they were waiting for him to come again. When he would appear the second time they would see him, and they too would be changed in their physical appearance. They would receive glorified bodies as Christ has. They would see Christ and would be like him. They would see him as he is. They would be like him as he is.
This is one of Paul's greatest arguments:
1 Corinthians 15:13 But if there be no resurrection of the dead, then is Christ not risen:
14 And if Christ be not risen, then
is our preaching vain, and your faith
is also vain.
15 Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not.
--In verse 13 he speaks of the resurrection of the dead in general--our physical resurrection which is yet to come. Christ was the first one, and is the only one to have risen from the dead. If there is no "resurrection" then our preaching is vain; our faith is vain; and we are found false witnesses. What an indictment!!
1 Corinthians 15:16 For if the dead rise not, then is not Christ raised:
--The conclusion of that passage. If there is no physical resurrection to look forward to, then Christ himself is not raised. There is a resurrection. Inasmuch as Christ is raised from the dead it is a sure thing that we also will be raised from the dead.
1 Corinthians 15:19 If in this life only we have hope in Christ, we are of all men most miserable.
--If there is no physical resurrection then we of all people are most miserable. What have we to look forward to?
There is a kingdom coming. Then after that: a new earth and a new heaven. These are not to be inhabited just by spirits.
1 Corinthians 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
--There is an order to everything.
First Christ was physically raised from the dead.
Then we will follow in that same kind of resurrection. We will be raised "at his coming."
Paul goes on from verse 49ff to describe the nature of our body, what type it will be. The word "resurrection" always refers to the resurrection of the body. No other religion claims to have a resurrected prophet. They know the word refers to the body. Muslims cannot claim that Mohammed arose from the dead. He didn't. His body is in the grave. "Resurrection" applies only to the body.
