 However, even according to this position that the scrolls that Jews possess today are not letter-perfect, the Torah scrolls are certainly the word-perfect textus receptus that was divinely revealed to Moses.Indeed, the consensus of Orthodox rabbinic authority posits this belief in the word-perfect nature of the Torah scroll as representing a non-negotiable prerequisite for Orthodox Jewish membership.Although even in Modern Orthodox circles, there are some Rabbis (e. g., Professor Marc Shapiro) that point out the numerous rabbinic sources from the Talmudic, Post-Talmudic, and medieval ages that claim that there were some changes to the text, which include whole verses, that were made deliberately during the Mishnaic era, and even during the times of the first temple.
