Klalei HaPsak (Halachic Decision Making): Difference between revisions

=== Kessef Misnheh & Beit Yosef ===

# Authorities are uncertain which work was written first, Kessef Mishneh or Beit Yosef. The number of cross citations from one book to another are too numerous in each direction to be convincing of one side or the other and, in fact, lead the Shulchan Gavoah<ref>Shulchan Gavoah (Klalim Siman 13)</ref> to determine that Rav Yosef Karo worked on both works simultaneously The Yad Malachi, however, argues that the Kessef Mishneh must have been completed after the Beit Yosef, because, in Kessef Mishneh, it says that the Shemitta is in year 5327, and in the end of Beit Yosef, it says the Sefer was completed in the year 5314. It's certainly possible, though, that he worked on both simultaneously and therefore referenced the Kessef Mishneh manuscript in Beit Yosef.<ref>Yad Malachi (Klalei HaKessef Mishneh 1-2)</ref> The Chidah disproves this claim, because the first printing of Beit Yosef was in 5310, and Kessef Mishneh was complete but not printed until the end of Rav Yosef Karo's life. As long as he was alive, he continued to work on the Sefer, and he passed away in middle of the printing endeavor.<ref>Shem HaGedolim (Sefarim, Maarechet Bet Ot 59, Maarechet Kaf Ot 50), Matnat Yado fn. 17.
