Specifically, in 1983, the Central Conference of American Rabbis passed a resolution waiving the need for formal conversion for anyone with at least one Jewish parent who has made affirmative acts of Jewish identity. This departed from the traditional position requiring formal conversion to Judaism for children without a Jewish mother.[38] The 1983 resolution of the American Reform movement has had a mixed reception in Reform Jewish communities outside of the United States. Most notably, the Israel Movement for Progressive Judaism has rejected patrilineal descent and requires formal conversion for anyone without a Jewish mother.[39] However, in 2015 the majority of Britain's Assembly of Reform Rabbis voted in favor of a position paper proposing "that individuals who live a Jewish life, and who are patrilineally Jewish, can be welcomed into the Jewish community and confirmed as Jewish through an individual process."[40] Britain's Assembly of Reform Rabbis stated that rabbis "would be able to take local decisions – ratified by the Beit Din – confirming Jewish status."[40]
