From the thread Bro Burk referenced, these thoughts show a physical resurrection.
1) The personal plural pronouns in Phil 3:20 are limited to the church, showing that the same must be held for that used in verse 21. This in turn shows that our vile body refers to the physical body of arms and legs. etc., that shall be fashioned like Jesus' body. It is not a different sort of "body" of covenant people, for example. The church is not vile nor ever has nor will be.
2) The BODY is a container in
2 Cor 5, showing that the idea of a spiritual body being not physical loses its "containing" function Paul required by his words.
3) We can be absent from the body with the Lord when we physically die, showing we have NO BODY at all in such a period -- not even spiritual.
3)
Romans 8 mentions the creation groans waiting for the redemption of our bodies when sons of God are manifested.
4) Jesus is said to have experienced "dieth no more, death has no more dominion over Him," in
Romans 6, indicating He has a physical body that cannot die. Otherwise, the point is moot since spirits do not die, anyway. The DIETH NO MORE must relate to what actually did die. Since we know Jesus' Spirit did not die, but only His body did, then that which DIETH NO MORE must also refer to the body that ONCE DIED.
5)
Romans 6 answers the issue of death in
Romans 5 that Adam brought into the world by His sin by having Jesus physically die.
