 In 1869 reformers again left Baith Israel , and , joining with dissenters from Kahal Kodesh Beth Elohim of Williamsburg , founded Temple Israel . Though many reformers had left the congregation , several reforms in the service were nonetheless introduced : the congregation abolished most piyyutim and the Priestly Blessing , and , in 1873 , introduced a confirmation ceremony for girls , led by the Reverend Dr. Tinter . The confirmation ceremonies , which had initially been held during the holiday of Sukkot , were eventually moved to the holiday of Shavuot ( the holiday during which the Reform movement held these ceremonies ) , and continued for both boys and girls ( in place of Bar and Bat Mitzvah celebrations ) until the 1940s .
