rabbi, a history question. how did the shulchan aruch become THE book?
the setup is strange. it was the summary volume of the mechaber’s own beis yosef, the competition was the rambam’s mishneh torah and the tur, and it was printed in venice in 1565, in the mechaber’s lifetime, right when printing was young. the tur was printed back in 1475 and mishneh torah around 1480 with six editions before 1500, so the other books had the press too, with a 90 year head start. yet the summary won.
1. why does everyone follow it? no sanhedrin adopted it, nobody voted. if it spread because of print and convenience, its authority rests on popularity. is that enough to make a book binding on every jew?
2. if the press made it popular rather than the book being inherently above the others, why are shitos outside it treated as inferior? plenty of rishonim and acharonim argued with its rulings and were never refuted, just outprinted. does the accepted book settle a machlokes, or just set a default everyone is scared to leave?
3. was the mapah the real win? the book only went universal after the rama’s glosses were folded in at krakow in 1578 to 1580 and it stopped being a sefardi book. does halacha pick its books by merger?
4. was it the format? no reasons, no sugya, just rulings. the maharshal attacked exactly this in his yam shel shlomo introductions, that rulings without sources make people stop learning. does the most usable book beat the deepest book?
5. who chose? the rabbis, or the printers and the market with the rabbis ratifying afterward? could it have gone the maharshal’s way, with no code at all?
bottom line, basically: if the shulchan aruch won on print and convenience rather than depth, is “everyone follows it” a halachic fact or a historical accident? and does the same logic explain the mishna berura or artscroll in our day?


Thank you Rabbi, thank you very much.
I think the question begins with a slightly mistaken premise. The Shulchan Aruch did not become the central halachic work merely because it was short, convenient, or happened to benefit from the printing press.
The real project was the Beit Yosef.
Rav Yosef Karo undertook an extraordinary project. Using the Tur as his framework, he went through the sources of practical Halachah from the Gemara through the major Rishonim and Poskim available to him. He brings the Rif, Rambam, Rosh, Ramban, Rashba, Ran, Mordechai, Semag and many others. He identifies where the Tur’s ruling comes from, whether it comes from a Mishnah, Beraita, Bavli, Yerushalmi or other source, explains the different positions, and frequently brings important opinions that the Tur itself omitted.
Rav Yosef Karo actually says this in his introduction. His intention was to create a work that would gather the laws together with their שרשיהם ומוצאיהם מהגמרא, their roots and origins in the Gemara, together with the different opinions of the Poskim.
That is why the Beit Yosef became so extraordinary. If you wanted seriously to learn a practical halachic issue, you suddenly had one organized work that could take you through an enormous portion of the earlier literature.
There really was nothing else quite like it.
The Rambam’s Mishneh Torah is an extraordinary work, but the Rambam deliberately gives you his conclusion and normally does not tell you all the competing opinions and sources behind it. The Tur gives you considerably more of the halachic discussion, but not remotely the enormous collection and analysis that Rav Yosef Karo subsequently placed around it.
Then came the Shulchan Aruch.
The Shulchan Aruch should really be understood together with the Beit Yosef. The Beit Yosef is the full study; the Shulchan Aruch is the short conclusion. In many areas, if you simply open a Shulchan Aruch without knowing the Beit Yosef behind it, you do not really know why the ruling is there or what competing opinions existed.
I think of the Shulchan Aruch almost as the chazarah. You learned the sugya through the Tur and Beit Yosef, and now here is the concise bottom line.
Then the Rema accomplished something equally important for the Ashkenazi world. His Darkei Moshe goes through the Beit Yosef and Tur and brings the Ashkenazi Poskim, rulings and minhagim that he believed needed to be added or given greater weight. Then, just as Rav Yosef Karo condensed the Beit Yosef into the Shulchan Aruch, the Rema condensed much of his practical disagreement into his Hagahot on the Shulchan Aruch.
That combination was remarkable.
You now had the Beit Yosef as the enormous source work, the Darkei Moshe adding the Ashkenazi material, and then the Shulchan Aruch and Rema giving you the practical summary on one page.
That, in my opinion, explains much more about the success of the Shulchan Aruch than simply saying that people liked a convenient little code.
Of course printing helped distribute these books. Printing helps distribute every successful book. But the Tur and Rambam had already been printed long before the Shulchan Aruch. The significance of Rav Yosef Karo’s project was the completeness and organization of the information.
There is another important point. The Shulchan Aruch becoming the central sefer does not mean Rav Yosef Karo became the Sanhedrin.
There is no principle in Halachah that after Rav Yosef Karo writes something nobody can disagree with him. The Rema disagrees with him constantly. The Maharshal disagreed with the whole methodology in important respects. Later the Shach, Taz, Magen Avraham, Gra and countless other Poskim disagree with particular rulings.
That is normal Torah learning.
The Shulchan Aruch became the central framework for the discussion. It did not end the discussion.
That is why I think it is a mistake when someone says, “The Shulchan Aruch says X, case closed.” The proper question is: Why does the Shulchan Aruch say X? What did the Beit Yosef bring? What does the Gemara say? What did the Rishonim say? Does the Rema disagree? Do later Poskim disagree? Was there a different minhag?
Rav Yosef Karo himself built the Beit Yosef precisely by asking those questions.
So in that sense, the Maharshal’s criticism was important. He was worried about people replacing real learning with a book of answers. And he had a point. A person can misuse the Shulchan Aruch by treating it like a rulebook that eliminates the sugya.
But that does not diminish the genius of the Beit Yosef project. Quite the opposite. Rav Yosef Karo created one of the greatest tools ever produced for learning practical Halachah.
So who “chose” the Shulchan Aruch?
No single person did. There was no vote. Generations of Torah scholars recognized the usefulness and greatness of the Beit Yosef, the Rema completed the picture for Ashkenazi communities, and subsequent generations organized their halachic discussions around that structure.
That widespread acceptance matters. But it does not mean that every ruling in the Shulchan Aruch became immutable law against which no Posek may argue.
And I would be careful comparing this to ArtScroll. ArtScroll became extraordinarily influential because it made enormous amounts of Torah accessible. That is a tremendous accomplishment, but accessibility does not give a translation or commentary independent halachic authority.
The Mishnah Berurah is a closer comparison because it became an enormously influential halachic work and, especially in many Ashkenazi communities, became the standard book people reach for in Orach Chaim. But even the Mishnah Berurah is not a Sanhedrin. Other Poskim can disagree with it, and Sephardi Poskim frequently do.
The Beit Yosef/Shulchan Aruch phenomenon was larger than either example because it created an entire common architecture for practical Halachah.
That is the important distinction.
The Shulchan Aruch did not become central merely because it was the easiest book to read. It became central because behind those few lines on the page stood one of the most comprehensive halachic research projects ever undertaken.
And even then, it remained the beginning of the modern halachic conversation, not the end of it.
