of Principles, for example, used the somewhat ambiguous formula "the spirit within us is eternal". Along these lines, the concept of reward and punishment in the world to come was abolished as well. The only perceived form of retribution for the wicked, if any, was the anguish of their soul after death, and vice versa, bliss was the single accolade for the spirits of the righteous. Angels and heavenly hosts were also deemed a foreign superstitious influence, especially from early Zoroastrian sources, and denied. Practice Liturgy The first and primary field in which Reform convictions were expressed was that of prayer forms. From its beginning, Reform Judaism attempted to harmonize the language of petitions with modern sensibilities and what the constituents actually believed in. Jakob Josef Petuchowski, in his extensive survey of Progressive liturgy, listed several key principles that defined it through the years and many transformations it underwent. The prayers were abridged, whether by omitting repetitions, excising passages or reintroducing the ancient triennial cycle for reading the Torah; vernacular segments were added alongside or instead of the Hebrew and Aramaic text, to ensure the congregants understood the petitions they expressed; and some new prayers were composed to reflect the spirit of changing times. But chiefly, liturgists sought to reformulate the prayerbooks and have them express the movement's theology. Blessings and passages referring to the coming of the Messiah, return to Zion, renewal of sacrificial practices, resurrection of the dead, reward and punishment and overt particularism of the People Israel were replaced, recast or excised altogether. In its early stages, when Reform Judaism was more a tendency within unified communities in Central Europe than an independent movement, its advocates had to practice considerable moderation, lest they provoke conservative animosity. German prayerbooks often relegated the more contentious issues to the vernacular translation, treating the original text with great care and sometimes having problematic passages in small print and untranslated. When institutionalized and free of such constraints, it was able to pursue a more radical course. In American "Classical" or British Liberal prayerbooks, a far larger vernacular component was added and liturgy was drastically shortened, and petitions in discord with denominational theology eliminated. "New Reform", both in the United States and in Britain and the rest of the world, is characterized by larger affinity to traditional forms and diminished emphasis on harmonizing them with prevalent beliefs. Concurrently, it is also more inclusive
