The Shulchan Aruch of Rabbi Yosef Karo: what it is, structure and how it is used

The Shulchan Aruch (שולחן ערוך), “the set table,” is the code of Jewish law that Rabbi Yosef Karo wrote in Safed and that was published in Venice in 1565. Together with the glosses of Rabbi Moshe Isserles, the Rema, it became the code accepted by most of the Jewish world.

How it was built
It is to a large extent a codification of the rulings of his Beit Yosef, although it also contains rulings that do not appear in it, drawn from books that Karo read afterward. It follows the structure of the Arbaah Turim of Rabbi Yaakov ben Asher, but more concisely and without citing sources.
Karo adopted as a rule the rulings of Alfasi, Maimonides and the Rosh (Rabbi Asher ben Yechiel), and accepted as authoritative the opinion of two of the three, with exceptions.
The Mappah
Rabbi Moshe Isserles wrote glosses that indicate where Ashkenazi custom differs from what the text, of Sephardic orientation, says. They are called the Mappah (“the tablecloth”). Most sources date its first appearance to a Kraków edition of 1571; others give 1569–1571. Since 1578, almost all editions include them: see the biography of the Rema.
Acceptance and criticism
The source tells that Karo had a modest opinion of the work and wrote it with young students in mind. It became the standard code for ritual and legal questions. The Ashkenazim accepted it together with the Rema’s glosses. His contemporaries criticized it: Rabbi Yom Tov Zahalon called it a book “for children and the ignorant,” and the Maharal, the Maharsha and the Bach objected that rulings were being made by the code without knowing its talmudic sources.
Sephardim and Ashkenazim
Its rulings generally follow Sephardic law and customs. The Ashkenazim generally follow the Rema where the two differ.
