Daniel 12
John Damascene
Daniel 12:2
"Many shall awake" means the resurrection of their bodies, for I do not suppose that anyone would speak of souls sleeping in the dust of the earth.… The Lord, too, has clearly shown in the holy Gospels that there is a resurrection of the body, for "they that are in the graves," he says, "shall hear the voice of the Son of God. And they that have done good things shall come forth to the resurrection of life; but they that have done evil, to the resurrection of judgment." Now, no person in his right mind would ever say that it was the souls that were in the graves. — ORTHODOX FAITH 4:27
Daniel 12:2
The dead shall rise again, and they that are in the graves shall awake. They that have kept the commandments of Christ and have departed this life in the true faith shall inherit eternal life; and they that have died in their sins and have turned aside from the right faith shall go away into eternal punishment. Do not believe that there is any true being or kingdom of evil or suppose that it is without beginning, or self-originated or born of God—forget such an absurdity! But believe rather that it is the work of us and the devil, come on us through our inattentiveness, because we were endowed with free will, and we made our choice, of deliberate purpose, whether it be good or evil. — BARLAAM AND JOSEPH 19:164-65
