Recognizing that certain of the more archaic aspects of Jewish liturgy contain passages and statements that apply more to past eras than to the present day―and can in some cases be offensive to segments of modern society―this book attempts to delineate the parameters of halachically permissible changes in the liturgy. This consideration argues that these changes should have precedents in traditional sources and that they should be made only when they correct anachronisms and defuse potential conflict, thus enhancing the experience of prayer for an ever-widening spectrum of Orthodox Jewry.
