Like many children, I drove my parents crazy by asking questions. One question I always had was, “Where did God come from?” Later I discovered how the question “Where did God come from?” differs from the question, “Where did the universe come from?” In an earlier post, I mentioned Aquinas’ Third Way to prove God’s existence, a version of the Cosmological Argument. Now if the universe is contingent, that is, it does not have the source of its existence within itself, then it must have a cause. Without the possibility of an infinity of contingent causes (for the infinity of contingent causes are still contingent), there must exist a Necessary Being that creates and sustains the universe. Now a necessary being cannot pass out of existence–so there is no issue of where a Necessary Being come from; God, the Necessary Being, just IS, ipsum esse, existence itself. Thus, the childhood question of “Where did God come from?” is an inappropriate question, a “category mistake,” to use Gilbert Ryle’s term.
But there is a psychological reason that we ask the question. When we see the world, the only conscious beings we know are humans and many animals. But humans and animals all die. Yet if we see a mountain in the distance or look up at the moon at night, psychologically it seems that they have existed forever and will exist forever. This is an illusion of our short life span as human beings. We do not have time to see massive geological and astronomical changes. But we do have time to observe the deaths of family members, beloved friends, and beloved pets. But there is no necessity that every conscious being be finite and contingent like us. I could not understand, as a child, how God could be conscious forever, past and future. Now I accept the Classical notion that God transcends time, but my mind cannot wrap itself around that concept–and why should it? For a species that cannot exhaustively understand finite things, it makes no sense that it could exhaustively understand God–such understand that we have is more at the level of an ant trying to comprehend human beings. It is still hard to grasp, having lost my best friend to cancer at the end of May, how a mind could exist eternally. But that is not a philosophical difficulty. The solution to the psychological difficulty is to accept that God, a Necessary Being who cannot not-be is required philosophically, and to realize that something can be true without our understanding it. Intellectual humility is a virtue.

I’ve always hated change. Perhaps that is part of being an Aspie (having been diagnosed with Asperger’s Syndrome), or perhaps it is that longing for something permanent lodged in the human soul. As a small child, I cried when my parents replaced my old bed with a new one. But more important losses came–my dog Fuzzy was killed by a car, my Uncle died suddenly when I was in my junior year of high school, my Granddaddy in my senior year of college, Granny while I was in graduate school. I remember the Sunday dinners at Granddaddy’s and Granny’s with all the great aunts and great uncles and my aunt and uncle. Meatloaf, black eye peas, lima beans, salad with rich French dressing, pecan pie, Coca-Cola cake, strong but good iced tea. Outside was a world of wonder under twin maples, and I’d swing across the gravel drive, lost in the moment. All those moments live only in memory–every moment is, as the philosopher Alfred North Whitehead (1869-1947) said, is “perpetually perishing.”
What does this have to do with Aquinas’ third argument in his Summa Theologica for God’s existence? The Third Way has to do with contingent beings and necessary beings. A contingent being is anything that is possible both to exist and not to exist. For example, you and I are contingent, as well as trees, dogs, cats, the earth, the moon, the stars, galaxies, and even the entire universe. It is possible for all things to pass out of existence. But if everything were contingent, if the universe has existed forever, then all would have passed out of existence (or at least the universe might “exist” as ruined husks of old stars and dead dark matter) by now. But things do exist now, so there must exist a necessary being, one that cannot pass out of existence, and this necessary being is God. Given the radical contingency of everything in our lives–we ourselves will lose all, literally, at death, it is comforting to realize that a necessary being must exist–a being who can never change, who is all-loving and all-powerful, who will restore everything that is good at the end of time. Aquinas’ Third Way speaks to me because my greatest fear has been to lose all in annihilation. It is not just my own annihilation that matters, but that of all those people (and animals) who loved me and whom I have loved–and I’ll even include some of the inanimate objects. A necessary being cannot let us down. He keeps contingent things in existence constantly–creation is not a point act but continues throughout time. If God were to (metaphorically speaking) remove His creative glance from the universe for one microsecond, everything would immediately pass into nothingness. Aquinas’ argument speaks to all of us who have suffered loss, who have felt the contingency of all finite things (especially the very old, who lose so many loved ones as they age). And we all suffer loss. But since God, the Permanent Thing, lives and creates the universe by His power and His love, we have a door that opens beyond the multitude of life’s changes. As the old hymn, “Abide with Me” says,
Change and decay in all around I see;
O Thou who changest not, abide with me.
