In the summer 0f 2016, I went to Portland, Oregon to attend the General Assembly of the Presbyterian Church USA. At the convention center, just outside of the exhibition hall, was an installation of Foucault’s Pendulum. Foucault’s Pendulum is a large leaded ball hanging from a cable, swinging slowly and tantalizingly back and forth. Just watching it swing is captivating and soothing. But it’s not a meditation device and it does not just swing back and forth. Its pattern changes ever-so-slightly with each swing, so that the ball will eventually knock down one of the many pegs that encircle the top of the pendulum. Foucault’s Pendulum is an experiment that uses gravity to demonstrate the earth’s rotation. Unlike the pendulum on a grandfather clock, it does not simply swing back and forth and it does not require someone to go in and reposition the weights occasionally for it to continue swinging. Foucault’s Pendulum is driven by the unseen power of the earth’s spinning axis, so the back-and-forth movements of the pendulum do not end up back where it started. Over 24 hours, the pendulum will knock down every peg along the top.
I think and speak of this pendulum often, so you’ve heard this description already. Beyond its brilliance as a scientific demonstration, I find Foucault’s Pendulum an apt metaphor for how God often works among us.
We often say, “The more things change, the more they remain the same.” That may be a modern version of Ecclesiastes 1:9, “There is nothing new under the sun.” In fact, the whole opening portion of the book of Ecclesiastes seems to lay the groundwork for what some call “the Myth of Eternal Return.” There is something comforting about this rhythm – knowing the “the sun will come out … tomorrow” can bring us calm in a turbulent night. But the Myth of Eternal Return can also lead to despair. If there is nothing new under the sun, we seem to be in a cycle of repetition, leading nowhere in particular. “Nations rise, nations fall”; “the rich get richer, the poor get poorer”; and other anecdotes try to capture the futility we often feel with “one step forward; two steps back.”
The Modern temper has often been convinced that the future can be different from the past. Whether we think of the science of evolution or the power of revolution, the one thing we take for granted is that an outcome can be substantially different from its origin. In that sense, we have embraced “the Myth of Progress.” Christianity has been partly responsible for giving us this temper with our belief that, “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (II Corinthians 5:17) (At the same time, the possibility of a different future often scares us, whether we think of a looming environmental disaster or unleashing a kind of AI-generated world that surpasses our control. In those moments we may echo some of the difficult language from the book of Revelation and wonder if doom is at hand. We might call that dystopian view, “the Myth of Regress.”)
Instead of seeing the Myth of Eternal Return and the Myth of Progress as either/or possibilities, I think Foucault’s Pendulum offers a way of gathering our different experiences within the promise of the resurrection. We really do rely on the sun coming out tomorrow. We really do look in the mirror and find ourselves becoming our parents. In that moment, we might agree with the writer of Ecclesiastes that there is nothing new under the sun. That part of our experience is like the giant ball swinging slowly back and forth on Foucault’s pendulum. At the same time, we really do make and keep disciplines that enable us to overcome addictions or learn new skills. We really do live in a world that is experiencing Climate Change, calling us to live differently than our trajectory suggests. At that moment, we echo the Apostle Paul that, in Christ’s resurrection, God is doing a new thing. That part of our experience is often like the barely noticeable change in the course of the pendulum, as it actually does knock down one peg and then another, demonstrating that there is more to its movement than a simple back and forth like the grandfather clock.
My hope here is to offer a metaphor of hope in times when it seems that our work is in vain and even when all we see are setbacks. I guess that’s just another way of repeating, “We have the resurrection, Chappies!”
