Sometimes it is good to meditate on the goal- in this case, on the body we hope to receive in the resurrection.
From Fr. John Hardonās Pocket CCC:
Qualities of the Risen Body
Special Qualities of the Glorified Body.
Since the first century, the Church has developed this revealed doctrine about the qualities of the risen bodies of the just. These qualities have been given technical names: impassibility, brightness, agility, and subtility. Each deserves some explanation.
Impassibility means that the risen body will no longer be subject to pain, or even inconvenience of any kind. Piercing cold will not affect the glorified body, nor will the glaring intensity of heat, nor can anything like the forces of nature hurt it. Since there will be no more death, neither will there be the earthly prelude to death, which is sickness and disease.
Brightness describes that property of the glorified bodies that will make them shine like the sun. In Christās own words, āThen the virtuous will shine like the sun in the kingdom of the Fatherā (Matthew 13:43). The Savior briefly manifested what this brightness is like in his transfiguration on āa high mountain.ā There in the presence of Peter, James, and John, āHe was transfigured. His face shone like the sun and His clothes became as white as lightā (Matthew 17:1-2).
This brightness is not common to all glorified bodies in the same degree. All the bodies after the resurrection will be impassible, but their splendor will differ for each person. As explained by St.Paul, āThe sun has its brightness, and the moon a different brightness, and the stars a different brightness, and the stars differ from each other in brightness. It is the same with the resurrection from the deadā (I Corinthians 15:41-42).
Agility is that quality of the risen body that frees it from the material burden that now presses it down. It will be able to move about with the greatest of ease and with a swiftness that depends only on the will. This is what the apostle meant when he said that our bodies are now sown in weakness, but on the last day they will be raised in power.
Subtility corresponds to what St. Paul calls āa spiritual body.ā Without ceasing to be material, that is extended in space and perceptible to the senses. The glorified body will be completely under the control of the spirit. It will be fully obedient to the soul.
If we look more closely at the foundation for these marvelous qualities of the risen body, we find them resulting from the soulās face-to-face vision of God. The beatific vision means just that. It beatifies; that is, makes the human soul perfectly happy in seeing the Holy Trinity. But it also beatifies the body with the soul in the indescribable joy of directly beholding the three Persons of the infinite Deity.
One closing observation on the state of the glorified body may answer some questions that come to mind. How will our bodies after the last day compare with the bodies we had on earth? The most detailed answer in Christian tradition is given in three whole chapters of St. Augustineās City of God. Only a few passages will be quoted here.
Code:
It is understood that no part of the body shall so perish as to produce deformity of the bodyā¦.
For all bodily beauty consists in the proportion of the parts; together, with a certain agreeableness of color. Where there is no proportion the eye is offended, either because there is something wanting, or too small, or too large. Consequently, there shall be no deformity resulting from want of proportion in that state in which all that is wrong is corrected, and all that is defective supplied from the resources which the Creator provides. All that is excessive will be removed without destroying the integrity of the substance.
In the resurrection of the flesh, the body shall be of that size which it either had attained or should have attained in the flower of its youth, and shall enjoy the beauty that arises from symmetry and proportion in all its members (The City of God, III, 19-21).
**
There is great value in these reflections on the resurrection of the body. They help to sustain us as we go through life, by assuring us that our efforts are not in vain. Above all, they offer the promise of being glorified like Christ, provided we have endured like Him.** In this we are encouraged by the first Bishop of Rome: āIf you can have some share in the sufferings of Christ, ā he says, ābe glad, because you will enjoy a much greater gladness when His glory is revealedā (I Peter 4:13).
The secret is to believe this and to act on what we believe.
All of this is consistent with the whole tenor of divine revelation. It is the individual person, each with his own unique body united with his own unique soul who will rise on the last day to receive the just recompense for his individual human conduct, in body and soul, during his mortal stay on earth.
