Raziela Harpaz, of the Chabad Hassidic group, has taken upon herself the mission of promoting the observance of seven Laws of Noah by all mankind.
According to the Torah, all humankind (the offspring of Noah, or Bnei Noach) is subject to seven Divine commandments. They are: to refrain from idolatry; to refrain from sexual immorality; to refrain from blasphemy; to refrain from murder; to refrain from theft; to refrain from eating the limb of a living animal; and to establish courts of law.
Judaism does not seek converts to Judaism, per se, but rather universal acceptance of the laws of God as they were revealed to Noah in the Bible, and illuminated by Torah scholars. In this way, Noahides are essentially followers of the world's oldest religion.
