The Karo Family

The Karo lineage has its roots in medieval Castile, and more precisely in Toledo, capital of one of the oldest and most prestigious Jewish communities of the peninsula. It was there that he who was to bear the name to the height of renown was born: Joseph ben Ephraim Karo was born in 1488 in Toledo, in the kingdom of Toledo, under the Crown of Castile, and died on March 24, 1575 in Safed. The patronymic, in its various forms, belongs to the old Sephardic stock of Castile.

Toledo was not a city like any other. It had been, at the heart of Iberian Middle Ages, a center of learning where translations, philosophy, poetry and rabbinic law intersected. Castilian Jewry had experienced there, in the preceding centuries, figures who had transformed its study of the Law: thus Rabbi Asher ben Yehiel and his son Jacob ben Asher, whose codificatory work — the Arba'ah Tourim, or "Rows" — would become the very matrix of Joseph Karo's great work [Jonathan Ray, Rabbi Asher ben Yehiel and the Transformation of Toledan Judaism, 2004, ref:10]. There is a remarkable continuity here: the child of Toledo would take up, a century later, the architecture bequeathed by the masters of his native city to build his own juridical edifice.

But the Spain into which Joseph Karo was born was already a Spain closing in on itself. The condition of Jews in the Christian peninsula, long fruitful despite its fragilities, had deteriorated since the pogroms of 1391 and the rise of the Inquisition [Béatrice Leroy, Les Juifs dans l'Espagne chrétienne avant 1492, 1993, ref:1]. The decision to expel, taken by the Catholic Monarchs, would seal the fate of the community and cast upon the roads a generation of which the child Karo was one of the members [Maurice Kriegel, La prise d'une décision : l'expulsion des Juifs d'Espagne en 1492, 1978, ref:7]. From Toledo, the lineage carried away no goods: it carried away a language, a memory of law, and that demand for knowledge which, in the Karo family, would never waver.

Joseph Karo was only four years old when the expulsion decree struck. Tradition, here corroborated by biographers, describes a childhood torn from his land: born in Toledo during the years of the Inquisition, he fled the country at the age of four, with his family, alongside the multitudes of Jews expelled from Spain in 1492. The experience of doubled expulsion marked an entire generation of Sephardic exiles: expelled from Spain at four years old, Karo endured a second expulsion, that of Portugal, before wandering from city to city.

This exodus was not a simple displacement: it was an entire reconfiguration of the Jewish map of the world. The Spanish exiles resettled in large waves across North Africa, Italy, and especially the Ottoman Empire, which welcomed them and where they reconstituted their communities and institutions [Joseph R. Hacker, The Sephardic Diaspora after 1492: Patterns of Resettlement, 2001, ref:5]. The case of the Karo family illustrates this pattern exactly. According to tradition, the family wandered from city to city, from country to country, without finding safe refuge until settling in Constantinople.

It was in this exile that knowledge was transmitted. The young Joseph was first instructed by his father: Joseph was first educated by his father, Rabbi Ephraim, a scholar in his own right, who was later appointed chief rabbi of Nikopol in Bulgaria, and Rabbi Joseph would subsequently cite numerous teachings received from him. Transmission did not cease at his father's death: after his father's death, he grew up in the house of his uncle, Rabbi Yitzchak Caro, who adopted him as his own son. This detail reveals a virtue of the lineage: kindness and care for the other, here the orphan taken in and raised in Torah by an uncle himself a scholar. In the trial of dispersion, the family knew how to make domestic solidarity the vector of intellectual continuity — a virtue that Jewish tradition holds as one of the highest, one that prefers to the monument the living bond.

Joseph Karo's itinerary in adulthood mirrors the geography of the great Sephardic centers of the Ottoman Empire. It was in Adrianople — Edirne — that he first established his intellectual foundations and conceived the colossal project of his life. Karo began the Beit Yossef in 1522 in Adrianople. Then came the Balkan and Anatolian stages: between 1520 and 1522, Karo settled in Edirne; he subsequently lived for some time in Nikopol, before heading toward the Holy Land, passing through Thessaloniki and Istanbul.

Thessaloniki, then the "mother of Israel," was a decisive encounter for him. Passing through Thessaloniki, he met the great Kabbalist Joseph Taitazak. This encounter inscribes Karo in a double tradition: that of the jurist and that of the mystic, which would never cease to dialogue within him. For the Sephardic world in exile was not merely an enterprise of survival; it was an extraordinary flowering of thought, where rabbinic law and Kabbalah nourished each other mutually [Henry Méchoulan (dir.), Les Juifs d'Espagne : histoire d'une diaspora, 1492-1992, 1992, ref:2].

In this period of formation, one reads one of the cardinal virtues of the lineage: talmudic learning pursued to exhaustiveness. The project of the Beit Yossef was not one more commentary, but an enterprise of rescue of the entire legal memory, at a moment when dispersion threatened to fragment customs. Thirty-two authorities, from the Talmud to the works of Rabbi Israel Isserlein, are summarized and discussed critically in the Beit Yossef; no other rabbinic work is comparable to it in the richness of its material. One measures the ambition: to gather, at the hour of scattering, the entirety of a legal tradition, so that no fragment of the patrimony would be lost in exile. In this, Karo became the guardian of the collective memory of Israel.

The destination of the journey was Galilee. Around the middle of the 1530s, Joseph Karo settled in a small town in the hills that would become, for a generation, the spiritual capital of the Jewish world. He later established himself in Safed, in Ottoman Galilee, where he arrived around 1535, having spent several years along the way in Salonique and Istanbul.

Safed was nothing like a metropolis; this is what makes its destiny so striking. In the 1500s, the city of Safed, in the Land of Israel, welcomed a great concentration of the greatest lights of the Torah: Rabbi Joseph Karo, Rabbi Isaac Luria, Rabbi Chaim Vital, Rabbi Moshe Cordovero, Rabbi Jacob Berab, Rabbi Moshe Alshich and Rabbi Shlomo Alkabetz, author of the famous Shabbat hymn Lekha Dodi, made their home there. Some of these scholars were among the exiles from Spain, and many of them being giants of the Kabbalah, Safed became the great center for this type of Torah study.

Karo immediately took his place among the masters there. In Safed, he was soon appointed a member of the city's rabbinical court, in the Beit Din of the famous Rabbi Yaakov Beirav; and when the latter reinstituted semikha — the official rabbinical ordination that had fallen into disuse for more than eleven centuries — Rabbi Joseph was among the first he ordained. This episode speaks to a collective virtue that the lineage came to embody: involvement in collective life and the dream of restoring unified juridical authority for a dispersed people. The attempt to restore ordination aimed at nothing less than giving Israel an instance capable of deciding for all — an ambition that extended, in the realm of law, the messianic hope of a gathering.

Karo did not merely sit on the court: he taught. He established a yeshiva there and taught the Torah to dozens of eager disciples. Among his most famous disciples were the renowned preacher Rabbi Moshe Alshich, the kabbalist Rabbi Moshe Galanti and the great kabbalist Rabbi Moshe Cordovero. Thus the Karo lineage, stripped of its earthly homeland, remade itself a spiritual progeny: contribution to Jewish thought took in it the form of teaching that spread across all branches of learning, from law to mysticism.

The work that brought the name Karo to the summit of Jewish Memory is the Shulchan Arukh, the "Table Set." It is the direct fruit of the monument completed in Safed. For it was there that Karo finished the great work begun a quarter century earlier: he began the Beit Yossef in 1522 in Andrinople and completed it in 1542 in Safed, in the Land of Israel; he published it between 1550 and 1559. This Beit Yossef — "House of Joseph" — is a commentary of unparalleled scope: written by Rabbi Joseph Karo, it is a long and detailed commentary on the halakhic code Arba'ah Turim of Jacob ben Asher, and the Shulchan Arukh, which Rabbi Karo wrote later in his life, is a condensation of its decisions.

Karo's insight was to understand that the very exhaustiveness of his work risked rendering it inaccessible. The Beit Yossef had become so encyclopedic that Karo understood he needed to create a more accessible text, for those who did not wish to traverse a long series of sources from the Mishna through the Talmud to the decisors of the Rishonim period. From this was born his practical masterpiece: he created the Shulchan Arukh, literally a table set where laws were carefully organized and ready to be consulted, following the division into four parts of the Tur and giving definitive guidance on how to act.

Its influence was immediate and universal. Written in Safed by Joseph Karo in 1563 and published in Venice two years later, the Shulchan Arukh, with its commentaries, is the most widely accepted compilation of halakha ever written. It thus became, in the received formula, the code of Jewish Law. This work speaks of the highest virtues of the lineage: the conception of halakha as service rendered to all, from the scholar to the humble believer. In reducing the endless debates of the Talmud to clear instructions, Karo did not impoverish the Law: he made it habitable. It is an act of intellectual charity, a way of extending a hand to the greatest number.

This generosity extended even to openness to the other rite. Karo composed his code according to Sephardic custom, but his work was fulfilled in the encounter with the Ashkenazi world. The halakhic decisions of the Shulchan Arukh generally follow Sephardic law and customs, while Ashkenazi Jews generally follow the decisions of Moses Isserles, whose glosses mark the points where Sephardic and Ashkenazi usages differ; these glosses are widely called the Mappa, the "tablecloth" laid upon the "Table Set." The image is beautiful and speaks for itself: the table set by the Sephardi of Toledo was only fully set when the Pole of Krakow laid his tablecloth upon it. By accepting that his code be thus completed, Karo testified to a tolerance and humility that made his work the meeting point of all branches of Israel. He was accorded two titles that speak to this status: he is also called Maran, "our master," or Ha-Mechaber, "the Author," that is, the halakhic author par excellence.

To this must be added the Kesef Mishneh, this commentary on the great code of Maimonides preserved in the Zakhor corpus. Karo's commentary on Maimonides' code, the Kesef Mishneh, is one of the standard commentaries on Maimonides' work. Karo accomplished there a work of learned piety: he strove to trace back to the talmudic sources of Maimonides' writings, which Maimonides had not cited in order to make the Mishneh Torah more accessible. Restoring the sources of an earlier master is an act of scholarly humility, which places one's own labor in service to the intelligibility of another.

We would have a truncated view of the lineage if we saw in Karo only the cold architect of law. The man who codified halakha with unparalleled rigor was also a mystic visited by divine grace. In this regard, a unique source illuminates the interiority of the master: his spiritual journal, the Maggid Mesharim, "the Preacher of Righteousness." Published in 1646, the Maggid Mesharim is a mystical journal in which Joseph Karo, over a period of fifty years, recorded the nocturnal visits of the Maggid—an angelic being, his celestial mentor, the Mishna personified. This visitor exhorted him to acts of righteousness and even ascesis, pressed him to study Kabbalah, and reproached him for his moral lapses.

This document places the lineage at the intersection of History and Memory: the archival item attests to the text, but its content pertains to inner experience, which the historian can describe without severing. Modern scholarship has underscored this dual nature of Karo: Joseph Karo was at once a jurist and a mystic, one of the greatest figures of Rabbinic Judaism and the author of the Shulchan Aruch. Like other Rabbinic ascetics who wrote on Talmudic or Kabbalistic subjects while carefully concealing their intimate mystical experiences, Karo left a journal recording messages received from a celestial mentor. His place within the circle of Safed is here decisive: a prominent member of the Safed circle that included Solomon Alkabets and Moses Cordovero, his journal offers new insights into the world of pre-Lurianic Kabbalah of the sixteenth century.

It is here that the most intimate virtue of the lineage is revealed: piety, understood as an uncompromising moral imperative. The most authoritative master of his time did not exempt himself from reproach; he kept a record of his own failings and submitted himself to a voice that called him to greater righteousness. This humility before the Law that he himself had codified is perhaps the most moving trait of the man: he who taught all Israel how to act judged himself with the same severity he would have reserved for others. The radiance of Safed as a center of learning extended long after him: a Yemenite Jewish traveler, Zechariah al-Dhahiri, visited Rabbi Karo's yeshiva in Safed around 1567 and recorded his impressions—distant testimony to the attraction that the master exerted on the scattered communities of the Jewish world, from Yemen to Europe.

From Toledo to Safed, the Karo lineage traced the very trajectory of Sephardic Judaism: that of a people who, driven from their homeland, transformed exile into foundation. The four-year-old child torn from Castile in 1492 became the man whose work unified the practice of the Law for all the diasporas of Israel. What the family lost in land, it regained in spiritual authority; what expulsion scattered, the Shulchan Aruch gathered together.

If one must name, among all others, the virtue that this lineage expressed most fully, it is the conception of halakha as an act of charity toward the entire community of Israel. For the work of Joseph Karo is not merely a feat of erudition; it is a gesture of kindness on the scale of a people. In setting the "table" where the scholar and the humble believer, the Sephardim and the Ashkenazi could equally nourish themselves, he made of the Law not a wall but a hearth. His juridical rigor was in service of accessibility; his immense knowledge, in service of clarity; his highest piety, tempered by the humility of one who judged himself. In this, the house of Karo participates in a virtue that the Jewish tradition has carried since Sinai: that of making the study of the Law not the privilege of a few, but the shared heritage of all. The table set in Safed in the sixteenth century remains laid for Israel — and therein lies the most enduring of legacies.
