Write As A Sermon for the MIT Chapel, in the Voice of John Polkinghorne

1. Opening: The World as Physicists Know It
Beloved friends,
Standing here in the MIT Chapel—this quiet center at the heart of an institution driven by inquiry—I feel the deep privilege of speaking as both a physicist and a priest. Many of you spend your days wrestling with the equations that probe nature’s foundations. You know well that beneath the reassuring veneer of classical intuition lies a world more surprising, more subtle, and more wondrous than we ever imagined.
Quantum theory tells us something startling: the most fundamental observables do not commute. You cannot measure them together without one disturbing the other. At the heart of physical reality is a refusal to allow safe neutrality. The universe itself insists upon choice, context, and transformation.
And it is here, in this unexpected place, that the Gospel speaks with uncanny resonance.
2. Bonhoeffer’s Challenge: The Christ Who Calls Us Out
Dietrich Bonhoeffer —whose courage still shames our timidity—reminded the Church that Christ is never a comfortable accessory to life. He does not sit quietly alongside our ambitions, values, and loyalties. He breaks them open. He demands that we stand either with him or against him. His presence forbids the luxury of moral indifference.
Bonhoeffer called this costly grace, the grace that dissolves all pretension.
And here, dear friends, is where science becomes a parable.
3. Christ as the Non-Commuting Operator
If I may borrow from the language of physics:
Jesus is the operator with whom nothing else in our lives commutes.
When you bring him into the system of your priorities, your identity, your desires—you cannot expect everything to remain unchanged. He is not a variable you add to stabilize the equation. He is the one who redefines the basis entirely.
Try to hold on to power while bringing Christ into view, and power collapses into service.
Hold tightly to resentment, and it collapses into forgiveness.
Hold autonomy as your highest value, and it collapses into a calling deeper than self-will.
Whenever we “measure” our lives against him—truly, honestly, without evasion—the act is transformative. Just as quantum observation reshapes the system it encounters, the presence of Christ reshapes the one who encounters him.
This is not coercion. It is revelation.
4. Gospel Encounters as Quantum Moments
The New Testament shows again and again that a genuine encounter with Jesus never leaves anyone in superposition.
The disciples in the boat fall down in awe.
The Gerasenes recoil in fear and ask him to leave.
The rich young ruler walks away grieving.
The blind man worships.
Thomas confesses, “My Lord and my God.”
No one meets the living Christ and remains undecided. Neutrality collapses. The system resolves into worship or rejection.
This is not because Christ seeks to corner us, but because truth, when revealed, cannot be held at arm’s length. As Bonhoeffer insisted, the call of Christ always creates a crisis—a moment of decision, a rupture in the old order.
5. What MIT Teaches Us About Faith
Many here study systems that behave unpredictably until probed. You know that the world at its deepest level is relational, responsive, and transformed by encounter. This is not foreign to Christian faith; it is its beating heart.
To seek truth—whether in the equations of quantum field theory or the parables of the Gospels—is to risk being changed by it. The worst mistake a scientist can make is to imagine we can investigate reality without allowing it to speak back. The worst mistake a Christian can make is to imagine we can draw near to Christ without surrender.
The chapel stands here on campus not to offer refuge from inquiry, but to remind us that truth is not merely something we analyze.
It is something that addresses us.
6. The Call: To Be Measured by Christ
My friends, let me speak plainly.
The living Christ stands before every one of us, not as an idea to critique, nor as a moral teacher to admire from distance, but as the one in whom all things hold together. He is the deep structure of reality, the Logos spoken of in the prologue of John’s Gospel, the One whose light burns through every darkened intellect and every shadowed conscience.
He will not commute with our carefully arranged ambitions.
He will not sit comfortably alongside our preferred identities.
He will not be merely added to the Hamiltonian of our lives as a stabilizing term.
He is the operator that redefines the entire system.
And he asks—quite simply—that we let him.
7. Benediction: A Prayer for Collapse Into Truth
May you, in your searching and striving, encounter the Christ who refuses to be sidelined.
May the illusions you cherish collapse gently before the radiance of his truth.
May neutrality give way to clarity, and caution give way to courage.
And may the One who stands at the center of all things become the center of your life as well.
In the name of the Father, and of the Son, and of the Holy Spirit.
Amen.
