With compelling citations from these two eminent Barcelona rabbis, Rabbi Wein captures the far-reaching contributions of each. First he examines the halachic rulings of the Rashba, covering everything from kashrus to appropriate punishment for informers to the Spanish Inquisitors. Then, concluding with the dramatic story of how Rabbeinu Yona changed from fierce critic of the Rambam to his dedicated advocate, we receive another lesson from the author of "The Gates of Repentance" as to how a Jew can make amends.
