Noahide Judaism
Noahide Judaism or Brith Olam or Spiritual Zionism (aka צִיּוֹנוּת רוּחָנִית) or Brith Shalom meaning the Covenant of Peace, describes Universal Judaism or Judaism for all being the Sabbath honouring form of Noahism that distinguishes Hasidei Umot haOlam from Hokhmei Umot haOlam. A Noahide who believes in Noahide Judaism is called a Noahide Hebrew, a Ma'amin, a Toshav and a Ger Shaar or Ger HaShaar (proselyte of the gate). Unlike other kinds of Noahism, Jews believe that Noahide Judaism guarantees those who protect this covenant a place in the world to come.
Six of the seven laws are universal (don't steal, don't murder, don't be lewd, don't use G-d's Name in vain, don't idolize anything, don't be unjust) but the 7th law concerning animal dignity is different for those who wish to follow Noahide Judaism. All of thr Laws of Noah are iterate in the Decalogue. The 7th Law for the Ger HaShaar is how one can keep holy the Sabbath day which is the only one of the Decalogue (10 commandments) which specifically mentions the Ger Shaar. The laws of Kashrut are what keeps Judaism different from any other moral system. Noahides are expected to study the laws of Kashrut in order to maintain kosher contact with Jews in the synagogue on Sabbaths and Yomtovs. Nevertheless, a Noahide still may not observe Sabbaths in exactly the same way that Jews do. They have to have a slightly different way, and that is precisely what the Petter Chamor tradition is focussed on.
Although Noahide Judaism existed for 26 generations before the Torah was revealed at Mount Sinai, most Noahide Hebrews tend to respect Hillel's Scribal Pharisees more than most Jews do and are therefore often at odds with most Jews as a result.
