The mark of a competent rabbinic authority is his/her capacity to seek the advice of another rabbinic authority in cases where the law may not be black and white since it is impossible to master the entire corpus of halakhic literature and keep up with all the responsa (“Dear Rabbi,” June 7). The current brouhaha over wearing ties on Shabbat ought not to be flippantly dismissed. Nor should a synagogue’s right to maintain certain standards be cavalierly denigrated. In fact, synagogue ordinances regarding how Jews ought to dress have a distinguished literary history. In addition, the spring 2013 issue of the “Journal of Halacha and Contemporary Society” contains a detailed essay called “Casual Saturday? Dressing Down for Shabbat,” which makes the case, based on clear halachic guidelines, for wearing a jacket and tie on Shabbat.
