The Philosophical Basics of the Resurrection

Probably of all my classes at Our Lady’s University, none had me more attentive than my course on St. Thomas Aquinas’ account of human nature, taught by Dr. John O’Callaghan. Unfortunately, this was my first formal exposure to the philosophy of St. Thomas, and as a 4000 level course, I do not think I got the most out of it. I had taken a course on Aristotle’s ethical theory the semester before, but though these two great minds were similar in worldview, Aristotle’s pagan terminology and approach was nowhere near a proper introduction to Thomas’ intellectually mammoth rational constructions.

Despite this, I did benefit from this study, and as I have only and always been interested in acquiring the truth and never in spouting off any philosopher’s theories word-for-word, this was not an insignificant benefit. One thing that really fascinated me during my study of Aquinas’ philosophy of human nature was in terms of the resurrection.

As is the relationship between theology and philosophy, divine revelation can invariably be confirmed by human reason. The saying, “philosophy is the handmaiden of theology” springs to mind. Basically, if our understanding were to be laid out on a line spectrum with things we know from human reason and things we know from divine revelation, each would generally lie on either side of the spectrum and there would be a gap in between. This gap represents our lack of full understanding of the higher bits of knowledge, specifically those things divinely revealed to us, creating what we call “mysteries”. Divine revelation gives us those truths that would otherwise be impossible to reach solely with our own reason, though these truths are coherent with our own human reason. Everything divinely revealed can be confirmed with the same human reason that we use to work a math problem or organize a closet or make a gourmet meal.

The resurrection of the body promised by Christ at his Second Coming is just one of those things that, with a little Thomistic ontology, is completely reasonable to believe, though the particulars certainly remain a mystery. First, it is important to remember that we are human beings (don’t forget that definition), and “human being” is defined as a living body animated by a rational, immortal soul. Therefore, it is accurate to say that when John dies, John (the unified human being) ceases to exist because his soul is separated from his body. However, John’s essence, his soul, is immortal and survives the body.

So our soul lives on, separated from our body which decays and fades away with time. At this point, do our souls just remain in Heaven? It is eternal beatitude, after all, so what more could we want or need? Why does Christ promise that our souls will be reunited with our bodies in the Resurrection? Is that really necessary after achieving eternal beatitude?

I certainly cannot say what is divinely necessary, but I can definitely say that it’s perfectly reasonable that I should be reunited with my body after I die. In the state after death, our human nature is divided: our soul is in Heaven and our decomposing body remains on earth. But since we were created as human beings (body and soul) and not as angels who are purely spiritual and incorporeal beings, it would seem a little odd that we should spend eternity in such a divided state, especially when our bodies are an intrinsic part of our own creation and being. (if they were not, why should we bother caring for them in this life?)

As an analogy to illustrate this, a free-floating balloon is caught by a child and tied down. The balloon’s natural destiny is to float away into the sky, but here, it is separated from that destination and tied to the ground. If the balloon was meant to remain close to earth, why was it filled with a lighter-than-air gas to begin with? Similarly, it is our natural destiny to be unified, soul and body. When we die, our soul is separated from our body and allowed to take root in Heaven. If this were the end of the story, then why did God create us with bodies in the first place? It seems perfectly natural to believe, then, that the destiny of our human nature is to be unified, body and soul, in eternal beatitude with God after the Resurrection.

So our use of human reason confirms the revelation of the Resurrection. I am not suggesting that while in Heaven after death, we will in some way miss our physical bodies or feel uncomfortable without them. This would suggest that eternal beatitude is deficient in some way. But as it has been revealed to the human race, Divine Justice promises to return us to our bodies at the end of time, and this is at the very least is something we can partially understand.
