We Are All Changing Judaism. The Question Is Whether We Admit It.

The Problem Isn’t Changing the Tradition. It’s Pretending You Didn’t.

Every morning I put on tefillin. Four compartments. Four passages from the Torah, one for each time the commandment appears in the written text.

But here is something most people don’t know: it wasn’t always four.

When archaeologists opened the caves at Qumran and examined the tefillin found there, they discovered something striking. Over half of those ancient tefillin contained the Ten Commandments alongside the standard passages, a different configuration entirely from what rabbinic Judaism eventually standardized. This wasn’t just a quantitative difference, one more compartment. It was a qualitative one, a different idea of what tefillin are for. The Qumran tefillin contained the Ten Commandments, possibly the very practice the Mishnah warns us against.

The Mishnah’s ruling in Sanhedrin 11:3 addresses exactly this kind of change, and its logic is worth sitting with.

The context is the zaken mamre, the rebellious elder, and which of his rulings makes him liable. The Mishnah rules:

If one says “there is no mitzvah of tefillin from the Torah,” one is exempt. This person has placed himself outside the system entirely. His position is clear, and he is no longer part of the interpretive conversation at all.

If one says “there should be five compartments,” one is chayav. Liable. Because there is greater stringency regarding rabbinic interpretation than Torah itself.

What makes this ruling striking is that the Mishnah does not ask whether the rebellious elder was honest about his disagreement. He may have stood before the Sages and argued his case openly. He may have said clearly, “I believe the law should be five, not four.” None of that matters. Once the Sages have ruled, continuing to rule otherwise, even sincerely, even transparently, is itself the violation. The danger the Mishnah identifies is not concealment. It is the refusal to accept that some questions, once argued through legitimate process, have been settled.

That is a hard teaching, and an old one. Tradition cannot survive if every generation reopens every question forever. At some point, a community has to be able to say: this has been decided, and we live by it.

But this Mishnah is talking about a different world from the one we live in. There is no Sanhedrin today. No body with the standing to settle, with finality, how a sincere Jew may understand the obligations of Jewish peoplehood. So when I read this Mishnah against the landscape of Jewish life today, I find myself drawn to a related question the Mishnah does not directly answer, but that its spirit presses on me to ask.

If no Sages exist today to settle our disputes the way the Sanhedrin once did, what do we owe each other instead?

I want to suggest, as my own extension of this teaching and not as the Mishnah’s ruling, that the answer is honesty. Not finality, since we no longer have a body that can grant it. But honesty about what we are doing.

We all change things. Every living Jewish community still inside the tent has innovated, reinterpreted, and built something the previous generation didn’t have. That is not a scandal. That is how Judaism has always survived and adapted to the times. The rabbis changed things. The mystics changed things. The Hasidim changed things. Every generation that kept this tradition alive changed something.

Without a Sanhedrin to rule on which changes are legitimate, the question shifts. It is no longer only whether a change has been authorized. It is whether we are honest about having made it.

Every community I have encountered believes, with complete sincerity, that its way of living Judaism is not a change but a recovery, not innovation but authenticity.

Nobody stands up and says “I am changing Judaism.”

Everyone says “I am recovering the authentic one.”

That instinct is understandable. But it closes off the very conversation that, in the absence of a Sanhedrin, is the only mechanism we have left for holding each other accountable. If your position is divine and unchanging, and mine is too, we are not in dialogue. We are simply waiting for the other side to give in.

So what does this Mishnah, read honestly and without overreaching, ask of us?

Not the silence of having changed nothing. None of us can claim that.

Just the willingness to say: this is mine. This is what my community chose. This is how we understood Judaism in our time. We believe in it deeply. We will defend it. But we will not present it to the rest of the Jewish people as if there were no other choices.

That is the posture this moment requires. Not because the Mishnah commands it directly. But because the Mishnah shows us what happens when a community stops being honest about the difference between what was received and what was decided, and we no longer have the Sages it once had to draw that line for us.

The tradition I inherited was shaped by people honest enough to argue, brave enough to decide, and humble enough to know the difference.

If Jewish life is going to find its way through the arguments tearing it apart today, that posture is where it has to start.

Not with who is most authentic. With who is most honest.
