The four wonderful characteristics of a resurrected body

 So it is with the resurrection of the dead. What is sown is perishable, what is raised is imperishable. ⁴³ It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power. ⁴⁴ It is sown a physical body, it is raised a spiritual body. If there is a physical body, there is also a spiritual body.

1 Corinthians 15:42-44

Based on this Scripture passage, Saint Thomas Aquinas defines four characteristics of what our bodies will be like in heaven; impassibility, subtlety, agility, and clarity.   I came across recently an article by a man named John Johnson for the Catholic blog Veritas.  He does a good explaining what they are, so I will let him speak:

First, Impassibility (“It is sown in corruption, it rises in incorruption…”). Not only will you live forever in heaven but the gift of impassibility means that the glorified body can suffer no corruption or pain, and it will not be subject to carnal passions. You won’t need any physical food and you won’t age. Your bodies will be animated, in a sense, by God, who is Life itself. You will have spiritual bodies – or, should we say, spiritualized bodies. No longer, tied to the dust of the earth from which you came, you will be totally aimed at God.

Next, the blessed will have subtlety. (“It is sown a natural body, it shall rise a spiritual body…”). By subtlety, we do not mean underratedness. Because our bodies will not be subject to any laws of material nature, nothing will stand in our way. The prime example of subtlety in Scripture is John 20:19 when Jesus walks through the walls of a locked room to get to the disciples. By the gift of subtlety, our bodies shall be able to freely penetrate other bodies (walk through walls). Interestingly, our bodies will even be subtle with respect to one another. Totally sharable, we will be able to completely communicate, through our bodies, our joys to our neighbor. Though I do not know of one that has been done, a further study on the connection to the gift of Beatific subtlety and the sexual urge to share a body in this life would be worthwhile.

Thirdly, you bodies will have what St. Thomas calls agility. (“It is sown in weakness, it shall rise in power…”). This is a good one. Because, in Heaven, your body will be so unified and obedient to your soul, it will do whatever you can think of. Think about how incredible this is: if you can think it, your body can do it. Yes, I will be able to dunk. This actually explains why every human longs to do things like fly and have super speed. God gave us an appetite for these actions because we are actually meant to be able to do them. And we do see agility, in its seminal form, in the natural order. Isn’t it true that everything we see well trained athletes doing on ESPN’s Top Ten Plays of the Week is due to nothing more than a body which is well trained and habitually obedient to the rational soul of the athlete? So the Blessed, with their agile bodies will be able to fly, float, have super strength and be able to move faster than a speeding bullet.

Lastly, our resurrected bodies will possess the gift of clarity. (“It is sown in dishonor, it rises in glory…”). This clarity, or “brightness,” will be the glory of the blessed soul which overflows through the head and the rest of the body. It is the light of glory which Jesus gives us a glimpse of at the transfiguration. We will possess the very intellectual light of God (lumen gloreae) by which we will see him in his light that is otherwise unapproachable. As crystalline, the heavenly glory of our bodies will present to all; their very organization and internal structure will be immediately visible. And yes, we will actually have halos - these will be a sign of our kingly reign with Christ. The means by which our glory was accomplished will also be visible to all. The doctors will have the crowns of doctors and the martyrs that of martyrs. The particular means will also be evident: John the Baptist might have some sort of scar around his neck. The statues of the apostles in Rome usually portray them holding the instrument of their martyrdom – this is not just a good means of catechesis, but an insight into the nature of their to-be glorified state. Our crosses, everything painful in this life, will be, one day, transformed into something glorious. There is a story St. Augustine tells of a man who was burdened by uncontrollable flatulence - in Heaven, he was blessed with the gift of wondrous musicality. 

A few words of my own to end this:

Let’s do everything we need to ensure we get to heaven by living and dying in a state of grace.  What glories await us!
