These debates cause great problems for recognition of Jewish marriages, conversions, and other life decisions that are touched by Jewish law. Orthodox rabbis do not recognize conversions by non-Orthodox rabbis. Conservative rabbis recognise all conversions done according to Halakha. Finally, the North American Reform and Reconstructionists recognize patrilineality, under certain circumstances, as a valid claim towards Judaism, whereas Conservative and Orthodox maintain the position expressed in the Talmud and Codes that one can be a Jew only through matrilineality (born of a Jewish mother) or through conversion to Judaism.
