In this book, Professor Sperber attempts to delineate the parameters of halachically permissible changes in Jewish liturgy -- changes that have precedents in traditional sources and that may correct possibly misogynist expressions found in our current prayers.  For example, he suggests that one can simply omit the prayer “she-lo assani isha”, and introduce the matriarchs into the silent ‘Amidah.  He argues that, because there is no standard version of Jewish liturgy,  “yet another nusah of tefillah [should develop], one that will be acceptable within the context of modern-day Orthodox feminist thinking, and which will hopefully gain ever wider legitimacy” (p. 129).

 This review presents a serious halachic critique of Daniel Sperber’s suggestions as to what can be changed in the nusach (wording/formulation) of standard Orthodox prayers.  The author believes that Sperber engages in an extended argument against R. Joseph B. Soloveitchik, as expressed in Ra’ayonos Al Ha-Tefillah, who forbids changing the text of our prayers.
