Orthodox Judaism:

Orthodox Judaism collectively considers itself the only true heir to the Jewish tradition. The Orthodox Jewish movements consider all non-Orthodox Jewish movements to be unacceptable deviations from authentic Judaism; both because of other denominations' doubt concerning the verbal revelation of Written and Oral Torah, and because of their rejection of Halakhic precedent as binding. As such, Orthodox Jewish groups characterize non-Orthodox forms of Judaism as heretical; see the article on Relationships between Jewish religious movements.

Please answer a question about this article. If the question is unanswerable, say "unanswerable". What do Orthodox Jewish movements consider all other non-orthodox moments?
