In the daily Amidah prayer, the central prayer in Jewish services, the petitions to accept the "fire offerings of Israel" and "the grain-offering of Judah and Jerusalem" (Malachi 3:4) are removed. In the special Mussaf Amidah prayer said on Shabbat and Jewish holidays, the Hebrew phrase "na'ase ve'nakriv" (we will present and sacrifice) is modified to read to "asu ve'hikrivu" (they presented and sacrificed), implying that sacrifices are a thing of the past. The prayer for the restoration of "the House of our lives" and the Shekhinah to dwell "among us" in the weekday Torah reading service is retained in Conservative prayer books, although not all Conservative services say it. In Conservative prayer books, words and phrases that have dual meaning, referring to both Temple features and theological or poetic concepts, are generally retained. Translations and commentaries, however, generally refer to the poetic or theological meanings only. Conservative Judaism also takes an intermediate position on Kohanim and Levites, preserving patrilineal tribal descent and some aspects of their roles, but lifting restrictions on whom Kohanim are permitted to marry.
