At the end of 2022, I learned a new definition for a word I already knew. I knew “ignition” was the act of setting something on fire. More specifically, like everyone else, I mostly associate the word with the process of starting a car powered by an internal combustion engine. The ignition used to be the place my key went - signaling the process that turning the key initiated. Now it’s just a button I press. And if you drive an electric car I guess you don’t need ignition at all, since, without internal combustion, there is nothing to ignite.
But last month I learned about the specific meaning of “ignition” in the field of nuclear fusion. On December 5th, scientists at the Nuclear Ignition Facility, using 192 lasers focused on a pea-sized pellet of hydrogen isotopes, caused a nuclear reaction that generated more energy than it consumed. It was the first time this feat has ever been accomplished by human agency, and it lasted for less than a hundred trillionths of a second.
I am told that this accomplishment was not a violation of the first law of thermodynamics, which states that, as a rule, energy cannot be created or destroyed. The details of nuclear ignition I will not get into, not only because they are beyond my ken, but also since the nay-sayers point out that the achievement of ignition on December 5th did not take into account all the substantial energy that was required just to run the facility, all of which actually matters in the equation. But people get excited at the prospect of a powerful and plentiful source of renewable energy.
The question that I’ve been asking myself since the announcement of successful nuclear ignition just twenty days before Christmas, is this: Was the birth of Jesus a kind of ignition that generated more energy than it consumed? Nuclear fusion, after all, is the process that powers the sun and the stars, which sounds an awful lot like the power of God to me, when I consider the heavens, the work of God’s fingers, the moon and the stars that he set in their courses (to borrow a phrase from the Psalmist).
Normally on the Sunday after Christmas we would be reading again the prologue to St. John’s Gospel which is at pains to remind us that the mystery of the Incarnation is the en-flesh-ment of the eternal Word of God, who was, and is, and is to be. We have a different reading because today is the Feast of the Holy Name. Although St. John didn’t have the language for it, I suspect that he would say that the fact of the Incarnation of the divine Word of God is not a violation of the first law of thermodynamics, since “he was in the beginning with God, [and] all things came into being through him, and without him not one thing came into being.”
It’s not just a coincidence, is it, that a star figures in the story of the Nativity? A twinkling, distant ball of nuclear fusion that generates more energy than is consumed (for a long, long time). It’s almost like it’s a sign, or a symbol. It’s almost like these guys knew what they were talking about.
I am not qualified to make any definitive statements about the first law of thermodynamics. Or about ignition. Or about nuclear fusion. Here’s what I have to say: Jesus is ignition. Jesus generates more energy than he consumes. He is the power of the sun and of the stars. And we know him by name. Scientists spent something like 70 years trying generate this kind of power, and they were able to do so (sort of) for less than a hundred trillionths of a second. But Jesus is the power of the sun and the stars, and he came to be with us.
There’s an interesting detail that St. Luke reminds us of in his account of the circumcision of Jesus, since that occasion, eight days after his birth, is the time that a boy-child would have been given his name. But the evangelist reports to us that Jesus was not given his name that day. St. Luke tells us that “he was called Jesus, the name given by the angel before he was conceived in the womb.” Jesus’ name was given to him before he was conceived, since Jesus was before, as he always has been and he always will be. Jesus is ignition: he is the power of the sun and the stars, and he is the power that called them into being with whatever sized bang was appropriate or required.
If the birth of Jesus was a kind of ignition, generating more power than it consumes, what does that power look like in the world? For some time now, I have been asserting four attributes of Jesus that the world is in desperate need of. Now that I know about ignition, I can see how these four attributes generate more energy than they consume.
First, Jesus is the Prince of Peace, against whom are arrayed enormous arsenals of energy to prevent him from establishing his kingdom. Warfare consumes vast amounts of energy and leaves everyone and everything around it depleted. But peace - which is the natural state of God, and the aim of the divine will - generates vastly more energy than it consumes.
Second, Jesus (with the Father and with the Spirit) is the maker of all human persons, each of whom is the work of his fingers, and each of whom shares in his holiness. This means that each of us carries something of the potential energy of the sun and the stars with us, just as we bear something of the divine imprint within us. We are much more than the sum of our physical parts.
Third, Jesus is the source and origin of all forgiveness, and forgiveness, since it is a function of profound grace, generates more energy than it consumes, and restores all the energy that we use up when we are at odds with God and with one another.
Fourth, Jesus is the chief minister of the divine economy of giftedness. He gives himself as a pattern of giving that all people, made in his image, and whose humanity he shares, are invited to imitate in some small measure. Whenever we give we are entering a state in which we may generate more energy than we consume: it is the nature of giving, which is a process born in the heart of God, that is not described by the laws of thermodynamics
These four attributes are not laws of thermodynamics or any other aspect of physics: they are characteristics of the One who was born in a stable; who was, and is, and is-to-be; who is himself ignition: the power of the sun and the stars; who was sent to us as the perfect manifestation of God’s love; and whose holy Name we know because he is not only our God and our Savior, our Light and our Life: he is also our friend, and our love; he generates more energy by far than he consumes; and his Name is Jesus.
