Sure, why not? Again, John saw their souls. Why would you try to say he saw them with bodies when he said he saw their souls? Why would he say that he saw their souls if they had bodies?
So now there is no symbolism with these souls, but a literal view of heaven?
This scene is symbolic of humans covered by the Atonement Covenant of the Lamb slain from the foundation of the world. These souls are as literal as viewing Jesus as a physical Lamb.
You have turned a symbolic reference into a literal event. These are not even martyrs. These represent the entire church from Abel until the rapture. All are souls slain under the alter.
The 5th Seal is not about naked souls without bodies in heaven.
The 5th Seal is the church glorified as symbolized by the putting on of white robes. These white robes are not symbolic of physical bodies.
This is the final completion of being a son of God. You are a soul, that has never changed. The body you have returns to dust. God places you in a new body in heaven. The only part lacking is the spirit. Those robes of white symbolize putting on the spirit which then completes the restoration of a son of God.
John did not see their souls. He saw the redeemed as being covered by the blood of the Lamb. They were not literally under an alter either.
If I had posted what you did, you would accuse me of being carnally minded without spiritual discernment.
Adam and Eve had physical bodies prior to Adam's disobedience. I am not sure why you think having a physical body from God is being carnally minded? Having a physical body is part of a trinity in the direct image of God, Jesus, and the Holy Spirit.
Jesus is not the carnal aspect of God, as He never had a mortal body of sin and death, as you put it. They all have physical bodies of God (spiritual) in Paradise. Not the dead flesh from Adam (natural). 2 Corinthians 5:1.
You literally claim the OT redeemed had to physically die twice just so they would not have a physical body, but a naked soul walking around in Paradise serving God day and night in that heavenly temple. Or just "trapped" under the alter?
When Jesus led captivity captive per Paul, Jesus did not leave the OT redeemed without life as a naked soul. Jesus escorted them physically all the way to God and presented them as the firstfruits of the church covered by the Atonement Covenant, via a physical Cross, symbolic of a Lamb slain from the foundation of the world. But the OT redeemed had to wait for the Cross to receive their last day resurrection. They are not waiting for another resurrection. They already were given the first resurrection. The first resurrection is the physical body they came out of their graves in per Matthew 27:52-53. That was permanent, not a half hazard accomplishment by Jesus. They were made alive and no longer physically dead. They would never taste death again. Physical death being a soul without a physical body.
