The circle of Rashi's connections, however, was limited to France and Lorraine. His chief correspondents were his teachers and their disciples.[124] It was only after Rashi's day, when communication between the Christian and the Moslem worlds became more frequent, that rabbinical authorities were appealed to from all the corners of Europe and Africa. Though his correspondents were not so widely scattered, the subjects touched upon by Rashi in his Responsa are very varied in character. He was consulted on the meaning of a Biblical or a Talmudic passage, on the text of the liturgy, on rules of grammar, on Biblical chronology, and, especially, on new cases arising in the practice of religion. These Responsa, inspired, so to speak, by actualities, by the come and go of daily affairs, introduce the reader to the material and intellectual life of the Jews of the time, besides furnishing interesting information concerning the master's method. One of the questions most frequently agitated regarded wine of the Gentiles, the drinking of which was prohibited to the Jews because it was feared that the wine had been employed for idolatrous libations. Cases of this kind turned up every day, because the Jews occupied themselves with viticulture[125] and maintained constant communication with the Christians. Rashi showed himself rather liberal. Though, of course, forbidding Jews to taste the wine, he permitted them to derive other enjoyment from it, the Christians not being comparable to the pagans, since they observed the Noachian laws. Rashi's grandson, Samuel ben Meir, explicitly states in Rashi's name that the laws set forth by the Talmud against the Gentiles do not apply to the Christians. The brother of Samuel, Jacob Tam, tells us that Rashi forbade the payment of a tax by using a sum of money left on deposit by a Christian. This decision, Jacob Tam adds, was intended to apply to the whole kingdom and, in fact, was accepted throughout France. This testifies not only to the great authority Rashi enjoyed, but also to the uprightness, the honesty of his character. Another of his qualities becomes apparent in a second Responsum treating of the relations between Jews and Christians. They carried on trade with each other in wheat and cattle. Now, the Mishnah forbids these transactions. "When this prohibition was promulgated," wrote Rashi, "the Jews all dwelt together and could carry on commerce with one another; but at present, when we are a minority in the midst of our neighbors, we cannot conform to so disastrous a measure." Rashi, it is therefore evident, knew how to take into account the needs of the moment, and accommodate rules to conditions.
