What is the most commonly asked question of a rabbi?

Jeffrey Rubenstein has argued that the accounts in Chullin and Avodah Zarah reveal an ambivalent relationship between rabbis and Christianity. In his view the tosefta account reveals that at least some Jews believed Christians were true healers, but that the rabbis saw this belief as a major threat. Concerning the Babylonian Talmud account in Avoda Zarah, Drs. Boyarin and Rubenstein view Jacob of Sechania as a Christian preacher and understand Rabbi Eliezer's arrest for minuth as an arrest by the Romans for practicing Christinaity (the text uses the word for heretic). When the Governor (the text uses the word for chief judge) interrogated him, the Rabbi answered that he "trusted the judge." Boyarin has suggested that this was the Jewish version of the Br'er Rabbit approach to domination, which he contrasts to the strategy of many early Christians, who proclaim their beliefs in order to provoke their punishment by death (i.e. martyrdom). Although Rabbi Eliezer was referring to God, the Governor interpreted him to be referring to the Governor himself, and freed the Rabbi. According to them the account also reveals that there was greater contact between Christians and Jews in the second century than commonly believed. They view the account of the teaching of Yeshu as an attempt to mock Christianity. According to Dr. Rubenstein, the structure of this teaching, in which a Biblical prooftext is used to answer a question about Biblical law, is common to both the Rabbis and early Christians. The vulgar content, however, may have been used to parody Christian values. Dr. Boyarin considers the text to be an acknowledgement that Rabbis often interacted with Christians, despite their doctrinal antipathy.
