The question of the relative value of the ceremonies in Judaism was brought to a focus through Moses Mendelssohn, who, in his "Jerusalem," presented a new view of the Jewish ceremonial laws. He proudly repelled the attempts of Christian writers to win him over to Christianity, and declared Judaism to be not a system of belief based upon creeds, but a revealed system of law based upon ceremonies. Frågan om ceremoniernas relativa vikt inom judendomen spetsades till genom Moses Mendelssohn, som i sitt verk "Jerusalem" presenterade ett nytt perspektiv på judisk ceremoniell lag och påstod att judendomen inte är något trosuppfattningssystem baserat på dogmer, utan ett lagsystem som baseras på ceremonier.Jewish Encyclopedia
