Siddur Sim Shalom () refers to any siddur in a family of siddurim, Jewish prayerbooks, and related commentaries, published by the Rabbinical Assembly and the United Synagogue of Conservative Judaism. There are four versions of the prayerbook, and two detailed commentaries that themselves contain the entire siddur. The commentaries are known as Or Hadash ("A New Light"). Original 1985 edition The original Siddur Sim Shalom was edited by Rabbi Jules Harlow, and published in 1985. It succeeded the movement's first Shabbat siddur, Sabbath and Festival Prayer Book (Siddur Tefilot Yisrael), by Rabbi Morris Silverman, edited by a commission chaired by Rabbi Robert Gordis and first published in 1946. Siddur Sim Shalom contained greater discussion of the beliefs and theology of Conservative Judaism. It contains services for weekdays, Shabbat and Jewish festivals. In accord with Conservative theology it contains prayers and services for Israel Independence Day and Yom HaShoah (Holocaust Memorial Day). It is egalitarian in usage, e.g. offering prayers for the wearing of tefillin and tallitot in both feminine and masculine form. While very traditional when compared to the prayerbooks of Reform Judaism, this siddur does contain a number of notable departures from the text used in Orthodox Judaism. Harlow writes that "Three of the early morning berakhot were modified to praise God for having created each individual in God's image, a free person and a Jew, rather than the conventional version which express gratitude for not having been created a woman, a slave or a non-Jew." Perhaps the most significant difference between Conservative and Orthodox siddurim is found in the Birkhot HaShachar section; this part of the morning service traditionally contained many passages describing sacrifices that used to be carried out in the Temple in Jerusalem. Many passages on animal sacrifices are not present in Siddur Sim Shalom. Harlow writes "The sacrificial ritual in ancient times was construed as means by which a Jew gained atonement for sin. After the destruction of the Temple and the consequential end of sacrifices there, the Jewish people were deprived of this means. To replace the readings on sacrifices, modern Conservative prayerbooks cite the talmudic teaching that deeds of loving-kindness now atone for sin; they draw upon rabbinic tradition to emphasize teachings about atonement and necessary behavior." Additionally, the Amidah for Shabbat & Festivals is supplemented by an alternative, meditative, poetic translative rereading of the Amidah, written by André Ungar. The pocket edition
