The majority of Orthodox and some Conservative Jews reject the idea that a woman can publicly read from the Torah or lead prayer services whenever there is a minyan (quorum of 10 males) available to do so. However, the public celebration of a girl becoming bat mitzvah in other ways has made strong inroads into Modern Orthodox Judaism and also into some elements of Haredi Judaism. In these congregations, women do not read from the Torah or lead prayer services, but they occasionally lecture on a Jewish topic to mark their coming of age, learn a book of Tanakh, recite verses from the Book of Esther or the Book of Psalms, or say prayers from the siddur. In some Modern Orthodox circles, bat mitzvah girls will read from the Torah and lead prayer services in a women's tefillah. Rabbi Moshe Feinstein, a prominent Orthodox posek, has ruled that bat mitzvah celebrations are permissible, but should not be held in a synagogue, because then they would be construed as imitating Reform and Conservative customs; in any case, they do not have the status of seudat mitzvah. Rabbi Ovadiah Yosef holds that it is a seudat mitzvah.
