Except of course there are over 1,000,000,000 (one billion) Hindus, and less than 50,000,000 (fifty-million) Jews.
Then it seems that some claim that more than half are secular Jews,who are those that believe they are part of the brotherhood of God's Chosen,but they don't believe in God. Some folks say that half of the secular Jews consider themselves part of the Reform movement or belong to Reformed Synagogues or Temples while others say that secular Jews don't belong to any group of Jews considered to be members of a designated or formal religious entity.
Then there is the rivalry and bitterness between Sephardic and Ashkenazi Jews and the Zionist and non-Zionists. It also seems there is a group that are called Karaites,who claim to be the only Jews who are committed to Torah and do not intermarry or consider non Torah Jews legitimate.Some think Jews have been Jews since the time of Christ and others say that most of the European Jews were converted somewhere in Russia in the eighth century A.D.
Not to forget the Reformed,Conservative and Orthodox Jews and the terms devout and observant that are also tacked on to the front of the word Jew quite frequently.It seems to mean something specific to those who use them,but I am unable to determine if they abide by the legalism of the Old Testament but ignore the Mosaic Law or vice versa. Then there seems to be something called chalacai (sp) which seems to be very important,something to do with ancestry and citizenship in Israel but it creates a lot of kerfuffle.
Once I thought I had at least figured out Orthodox Jews and was surprised to find that there are Hasidic and Lebevitcher's and something else of which I think Rabbi Meyer Kahane was a member. I was told he was a Cohen and that was the only tribe that could trace their patronage back to David and on and on it goes with Orthodoxy.
Recently I have noticed some movie stars studying Kabbala,and some say this is authentic Jewry while others say that Jews are Talmudic and that is the book of books,not the Kabala,not the Torah but the Talmud.
Several years ago on Free Republic I asked a Jewish man about something and the ensuing discussion included0 "righteous gentiles" and Noachide Laws. Lately I have noticed on these boards some more discussion of the efficacy of Noachide Laws and I get very wary. It seems to me that universal courts set up to judge adherence to the other six laws could,if they chose to,throw all Christians into a category of "practioners of idolotry",which would be a crime the way I read it. Any thoughts sorry this is a little rattled and unfocused appearing but there does seem to be a lot of confusion on this issue. Are you Jewish?
50 million? You must be joking. There aren't anywhere near that many. There are only 5 million of us in Israel. Global numbers aren't more than 14 million or so, and that's probably an inflated estimate.
