Yonah Gerondi (Rabbeinu Yonah) was a Spanish rabbi, Talmudist and ethicist. His best-known work is Sha'arei Teshuva, a comprehensive work on repentance. He also wrote chiddushim (Talmudic novellae) on a number of tractates, quoted by contemporaries and later authors. He was one of the most prominent opponents of the Rambam's philosophical works. When the attacks on the Rambam's works culminated in a public burning of wagon-loads of Talmud by Christian authorities, Rabbeinu Yonah publicly admitted his error in involving outside players, and gave Rambam a prominent and revered place in his teaching. It is surmised that this turn of events motivated Rabbeinu Yonah to write Sha'arei Teshuva.Yonah Gerondi (Rabbeinu Yonah) was a Spanish rabbi, Talmudist and ethicist.
