Levels of orthodoxy in Judaism

Orthodox Judaism is not a unified movement; rather it is composed of many different groups with intersecting beliefs, practices and theologies. In their broad patterns, the Orthodox movements are very similar in their observance and beliefs. However, they maintain significant social and halakhic (legal) differences due to their varying attitudes concerning (a) the role of women in Judaism, (b) relations with non-Orthodox Jews, (c) attitudes toward modern culture, and (d) how to relate to the modern State of Israel. The following web page gives information about and/or direct links to over a dozen distinct Orthodox rabbinical bodies and movements.
