Noahide Judaism

Noahide Judaism (צִיּוֹנוּת רוּחָנִית) is what distinguishes Hasidei Umot haOlam from Hokhmei Umot haOlam. It is also called Brith Shalom. A Noahide who believes in Noahide Judaism is called a Ger Shaar or Ger HaShaar (proselyte of the gate) or Maamin.

Six of the seven laws are universal (don't steal, don't murder, don't disrespect animal dignity, don't be lewd, don't use G-d's Name in vain, don't idolize anything) but the 7th law of Deen is different for those who wish to follow Noahide Judaism. The Deen of the Ger HaShaar is based around keeping holy the Sabbath day which is the only one of the 10 commandments which specifically mentions the Ger Shaar. Nevertheless, a Noahide 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 sorted out.
