Everyone is talking today about the 50th anniversary of the Rev. Martin Luther King Jr.’s historic “I Have a Dream” address. And for good reason, of course. But there was another big speech in Washington that day — the one delivered by Rabbi Joachim Prinz, president of the American Jewish Congress. In fact, some say, before  MLK gave a speech for the history books, it looked like Prinz had stolen the show.

The speech was an eloquent sermon on the need for good people to speak out — with added power coming from a German-born rabbi who found refuge in the United States after the Nazis came to power.

Much energy has been devoted to the question of why American Jews are sooooooo liberal. I suspect that for many, this speech just about sums it up.  The key passage:

It is for these reasons that it is not merely sympathy and compassion for the black people of America that motivates us. It is above all and beyond all such sympathies and emotions a sense of complete identification and solidarity born of our own painful historic experience.

When I was the rabbi of the Jewish community in Berlin under the Hitler regime, I learned many things. The most important thing that I learned under those most tragic circumstances was that bigotry and hatred are not the most urgent problem. The most urgent, the most disgraceful, the most shameful and the most tragic problem is silence.

You can listen to the speech here. Full text below:

I speak to you as an American Jew.

As Americans we share the profound concern of millions of people about the shame and disgrace of inequality and injustice which make a mockery of the great American idea.

As Jews we bring to this great demonstration, in which thousands of us proudly participate, a two-fold experience — one of the spirit and one of our history.

In the realm of the spirit, our fathers taught us thousands of years ago that when God created man, he created him as everybody’s neighbor. Neighbor is not a geographic term. It is a moral concept. It means our collective responsibility for the preservation of man’s dignity and integrity.

From our Jewish historic experience of three and a half thousand years we say:

Our ancient history began with slavery and the yearning for freedom. During the Middle Ages my people lived for a thousand years in the ghettos of Europe . Our modern history begins with a proclamation of emancipation.

It is for these reasons that it is not merely sympathy and compassion for the black people of America that motivates us. It is above all and beyond all such sympathies and emotions a sense of complete identification and solidarity born of our own painful historic experience.

When I was the rabbi of the Jewish community in Berlin under the Hitler regime, I learned many things. The most important thing that I learned under those tragic circumstances was that bigotry and hatred are not ‘.the most urgent problem. The most urgent, the most disgraceful, the most shameful and the most tragic problem is silence.

A great people which had created a great civilization had become a nation of silent onlookers. They remained silent in the face of hate, in the face of brutality and in the face of mass murder.

America must not become a nation of onlookers. America must not remain silent. Not merely black America , but all of America . It must speak up and act,. from the President down to the humblest of us, and not for the sake of the Negro, not for the sake of the black community but for the sake of the image, the idea and the aspiration of America itself.

Our children, yours and mine in every school across the land, each morning pledge allegiance to the flag of the United States and to the republic for which it stands. They, the children, speak fervently and innocently of this land as the land of “liberty and justice for all.”

The time, I believe, has come to work together – for it is not enough to hope together, and it is not enough to pray together, to work together that this children’s oath, pronounced every morning from Maine to California, from North to South, may become. a glorious, unshakeable reality in a morally renewed and united America.
