In 1790, Moses Seixas of Newport, Rhode Island, and Manuel Josephson of Philadelphia corresponded, with Josephson composing what effectively amounts to a halachic teshuvah. Josephson raised concerns about the conduct of the Touro Synagogue in Newport, arguing that elements of the service were not being properly observed. The exchange provides an important window into the religious commitments and halachic awareness of early American Jews. It also stands as one of the earliest examples of a rabbinic-style teshuvah in the formative years of Jewish life in the United States.

From Philadelphia to Newport: An Early American Teshuvah (1790)

In this final class of the series, we will examine the Rebbe’s statements and correspondence regarding going up to Har Habayis.

By studying the available sources, we will seek to better understand what the Rebbe did—and did not—say about this complex and significant question.

This is the fourth and final installment on this topic. 

What Did the Rebbe Say About Going on Har Habayis?

Whether Jews may enter Har Habayis largely depends on whether we know where the Beis Hamikdash stood.

A common assumption is that we don’t know for sure, but that assumption has a history.

This class traces the story of this uncertainty, primarily through the accounts of Jewish travelers who visited Eretz Yisrael and recorded what they saw and heard.

This is the third installment in a series about going up onto Har Habayis.

Is the Dome of the Rock Where the Mikdash Stood?

The bar mitzvah ceremony didn’t always look the way it does today. In fact, for much of Jewish history, it barely looked like anything at all.

In this episode, we investigate: When did a ceremony first appear? What did it look like? When did bar mitzvah boys start receiving an aliya? Leining? Leading davening? A derasha?

We’ll trace its evolution among Ashkenazi Jews from the eleventh century through the seventeenth century.

The Boy at the Bimah: A History of Bar Mitzvah Celebrations

In the spring of 1096, crusading armies swept through the Jewish communities of the Rhineland, leaving devastation in their wake.

This class traces how those events gave rise to rituals of memory.

In the community of Worms, fast days were proclaimed on the 23rd of Iyar and Rosh Chodesh Sivan, accompanied by elaborate mourning customs.

We’ll see how in 1716, when Rosh Chodesh Sivan fell on a Friday, rabbinic authorities clashed over davening Maariv early that afternoon.

We conclude by tracing the demise of these fast days while noting how other rituals, such as the recitation of Av HaRachamim, have endured to this day.

The First Crusade: The 1096 Massacres and the Rituals They Created

In the late 1920s, a Jerusalem rabbi cited an obscure passage describing a certain Rabbi Moshe’s pilgrimage to the Holy Land, including what appeared to be a visit to the Temple Mount itself. He seized on it as proof that going there was halachically permitted.

This sparked a fierce debate over the passage: Was it even credible? Who exactly was this Rabbi Moshe? Did the text actually refer to the Temple Mount? And if a great rabbi really did go there, what would that mean for us today?

This is the second installment in a series about going up onto Har Habayis.

Did Rambam Actually Set Foot on Har Habayis?

Mechiras chametz is today a standard part of observing Pesach. But how did this practice come to be, and how has it evolved over the centuries?

In this class, we analyze the relevant sources in Ashkenazic and Sefardic texts, revealing two distinct approaches to this topic. We’ll then find how the more the sale was refined to accommodate the seller, the more complications it introduced, requiring a series of complex adjustments and, eventually, triggering voices of opposition.

All along, we’ll wrestle with a central issue—drawing the line between legal creativity and legal fiction.

The Controversial History of Mechiras Chametz

There’s a well-known story about Sir Moses Montefiore going up onto Har Habayis during one of his seven legendary trips to Eretz Yisrael.

But once you begin looking into it, you quickly discover that there are several versions of the story, each one telling it a bit differently: when he went up, why he did it, how he did it, and what the rabbinic community’s reaction was.

As we’ll see, a great deal depends on who is telling the story.

In this class, we’ll return to the sources and try to piece together what actually happened.

This is the first installment in a series about going up onto Har Habayis.

A Scandal on Har Habayis: The Montefiore Story

The Mishneh Torah printed in Venice in the 1570s was the product of a broad and deliberate program of censorship. Beyond removing the handful of references to the Christian founder, which we discussed in the prior class, the censors altered many other words and phrases. In some places, entire laws disappear; in others, the language is carefully adjusted to soften its force. In this class, we trace the principles that guided the censors and examine how their work left a lasting imprint on one of Judaism’s foundational texts.

Censoring the Rambam: Part II

In October 1949, The New York Times announced a sensational discovery: an ancient manuscript of Mishneh Torah was discovered and it contained a long-lost provocative passage about the Christian founder. The headline sparked excitement, but the story was riddled with errors. In this class, we trace the real history of that controversial passage and examine when, how, and why it was cut by the censor.
