You'll have to specify what era you're interested in. In olden times, there have been groups which branched away from normative Judaism: the Jewish idolaters, Hellenisers, Sadducees, Baithusim (Boethusians), Essenes, and followers of false messiahs such as the Sabbateans and Frankists. All of them have gone lost to history. The Karaites also, are a mere shadow of their past numbers.
In fact there are a number of movements within Judaism. The three main ones are: Orthodox, Conservative, and Reform. Within Orthodox Judaism there are several 'sects', and while of course all Jews share the same core beliefs, the groups may disagree passionately on other issues. Judaism as a religion has always encouraged debate and discussion. There is also Progressive Judaism and Reconstructionist Judaism, but these are not as large or influential as the three major movements outlined at the start of this answer. And the groups/movements are 'fluid' in that any Jew can walk into any Synagogue, in any country, and immediately feel at home, even if they are not part of that particular movement. -----------------------------------------------------------------------------------------------
Orthodox, conservative, reform, and re-constructionist.
There are three sects of Judaism: Orthodox, Conservative and Reform.
There has virtually never been a time in Jewish history where there were no differing sects of Judaism. Sects come about as the result of different interpretations of the Torah and Talmud.
There are not three sects of Judaism. It is just that three movements of Judaism: Orthodoxy, Conservatism, and Reform are the most dominant movements in Judaism. The others merely command fewer followers.
Basically there are 3 sects; Orthodox, Reform and Conservative. Additionally, within those sects there are also Re-constructionist Judaism and Jewish Renewal.
Yes, for most sects of Judaism.
No. Most sects of Christianity do proselytize, but not all. Almost no sects of Judaism proselytize. Most sects of Islam, including controversial sects like the Nation of Islam and Ahmadiyya, proselytize, some sects of Hinduism also proselytize, and in Asia, several sects of Buddhism actively proselytize.
i think there are no sects
Judaism, Christianity, and Islam.
No, there are many sects. Mystic, traditional etc.
Judaism is divided into Sephardim & Ashkenaz. Ashkenaz are divided into Orthodox, Conservative, & Reform. A forth sect is called Reconstructionist.
Christianity is the largest with roughly 2.1 billion adherents across its various sects. Islam is second with roughly 1.7 billion adherents across its several sects. Judaism is substantially smaller, with roughly 14 million adherents.
I assume you mean the Islam, Christianity, and Judaism. Well Judaism came first with their Torah, eventually the descendants of Abraham split apart, and spread out. hundreds of years past and small sects began to form all following the torah, but with slightly different interpretations. Then within each sect, a prophet (Jesus, Muhammad) came and created more information which completely separated the sects into what would become modern day Islam and Christianity... With the remaining followers of original Judaism left behind
