Reform Judaism has made greater alterations to the traditional service in accord with its more liberal theology including dropping references to traditional elements of Jewish eschatology such as a personal Messiah, a bodily resurrection of the dead, and others. The Hebrew portion of the service is substantially abbreviated and modernized and modern prayers substituted for traditional ones. In addition, in keeping with their view that the laws of Shabbat (including a traditional prohibition on playing instruments) are inapplicable to modern circumstances, Reform services often play instrumental or recorded music with prayers on the Jewish Sabbath. All Reform synagogues are Egalitarian with respect to gender roles.
