John of Damascus — on Dan 12:2 (ORTHODOX FAITH 4:27)

“"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.”
