Augustine of Hippo
"The rest of the dead," he says, "did not live" (Rev 20:5). For now is the hour when the dead hear the voice of the Son of God, and those who hear shall live (Jn 5:25). But the rest of them do not live.
The addition, "until the thousand years were ended," must be understood to mean that they did not live at the time when they ought to have lived, passing from death to life.
Therefore, when the day comes on which the resurrection of bodies will take place, they will come out of the graves not unto life, but unto judgment. That is, they will come unto condemnation, which is called the second death.

For whoever did not live before the thousand years were ended, that is, throughout the whole period in which the first resurrection takes place, did not hear the voice of the Son of God and pass from death to life.
At the second resurrection, which will be the resurrection of the flesh, he will finally pass with that flesh into the second death.
Then it is said: "This is the first resurrection. Blessed and holy is he who has part in the first resurrection" (Rev 20:5-6). That means the one who is a participant in it.
A participant in it is one who not only returned to life from the death that consists in sins, but also remained steadfast in the life to which he returned.
"Over them," he says, "the second death has no power." Therefore it has this power over those others of whom he said above: "The rest of the dead did not live until the thousand years were ended."
For however long each of them lived in the body during that whole interval called a thousand years, none returned to life from the death in which ungodliness held him.
Had he thus come to life, he would have become a participant in the first resurrection, and the second death would have had no power over him.
All who have not been freed by the one Mediator of God and men from that mass of perdition which came from the first man will indeed rise, each with his own flesh. But they will rise for punishment with the devil and his angels.
Whether they will rise with the defects and deformities of their bodies, whatever corrupted and misshapen members they once had, is not a question with which we need weary ourselves.
The uncertain outward form or beauty of those whose portion will be certain and eternal condemnation should be of no concern to us.
Nor can it interest us how something in them will be incorruptible if it suffers pain, or how something is corruptible if it cannot die.

For true life exists only where there is blessed life. True incorruption exists only where well-being is disturbed by no suffering.
Where the wretched are not permitted to die, death itself does not die. Where unceasing grief does not cease, corruption itself does not end. In Holy Scripture this is called the second death.
This is certainly not said only of bishops and presbyters, who at present alone are called priests in the Church. Just as we call all Christians by reason of the mystical anointing, so we also call all priests, because they are members of the one Priest.
Concerning them the Apostle Peter says: "You are a chosen race, a royal priesthood" (1 Pet 2:9).
Briefly and in passing, yet aptly, the thought is inserted that Christ is God through the expression "priests of God and of Christ," that is, of the Father and the Son.
For Christ became the Son of Man in the form of a servant, and was also appointed priest forever according to the order of Melchizedek (cf. Ps 109:4).
