Abrahamic religions "Abrahamic traditions" has been challenged. In 2012, Alan L. Berger, Professor of Judaic Studies at Florida Atlantic University, in his Preface to "Trialogue and Terror: Judaism, Christianity, and Islam after 9/11" wrote that there are "commonalities", but "there are essential differences between the Abrahamic traditions" both "historical and theological". Although "Judaism birthed both Christianity and Islam", the "three monotheistic faiths went their separate ways". The three faiths "understand the role of Abraham" in "differing ways", and the relationships between Judaism and Christianity and between Judaism and Islam are "uneven". Also, the three traditions are "demographically unbalanced and ideologically diverse". Also
Christianity and Judaism biblical food laws, for example the practice of Ital in Rastifarianism. Jehovah's Witnesses do not eat blood products and are known for their refusal to accept blood transfusions based on not "eating blood". Judaism does not see human beings as inherently flawed or sinful and needful of being saved from it, but rather capable with a free will of being righteous, and unlike Christianity does not closely associate ideas of "salvation" with a New Covenant delivered by a Jewish messiah, although in Judaism Jewish people will have a renewed national commitment of observing God's commandments under the New Covenant, and
