This glory of the body, however, does not belong only to the End but is foreshadowed at various moments throughout salvation history. Before the fall the bodies of Adam and Eve shone with light in Paradise , and they were “covered with God’s glory in place of clothing” (Homilies 12:8).
Once they had fallen into sin, this robe of glory was taken away from them and they were left naked (cf. Genesis 3:7). Then at Moses’ descent from Mount Sinai, after the giving of the Law, the final restoration of our bodily glory was briefly anticipated when his face shone so brightly that he had to cover it with a veil (cf. Exodus 34:29–35): “He went up as a mere man; he descended, carrying God with him….The Word of God was his food and he had a glory shining on his countenance” (H. 12:14). A far more significant foretaste of the eschatological glory came at Christ’s own transfiguration: “As the body of the Lord was glorified when he climbed the mount and was transfigured into the divine glory and into infinite light, so also the bodies of the saints are glorified and shine like lightning” (H. 15:38). What happened then to the Savior will happen to all true Christians in the age to come.
In so far as anyone, through faith and zeal, has been deemed worthy to receive the Holy Spirit, to that degree his body also will be glorified in that day. What the soul now stores up within shall then be revealed as a treasure and displayed externally in the body…. The glory of the Holy Spirit rises up from within, covering and warming the bodies of the saints. This is the glory they interiorly had before, hidden in their souls. For what they now have, that same then pours out externally into the body (H. 5:8–9).
