For Rabbinic Judaism, the laws governing conversion (gerut) are based on codes of law and texts, including discussions in the Talmud, through the Shulkhan Arukh and subsequent interpretations. (Many of the guidelines of accepting converts are based on the Book of Ruth and the manner whereby Ruth was brought into the fold through her mother-in-law, Naomi).[1] These rules are held as authoritative by Orthodox Judaism and Conservative Judaism.[citation needed]
