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
Abrahamic religions permitted food known as kosher in Judaism, and halal in Islam. These two religions prohibit the consumption of pork; Islam prohibits the consumption of alcoholic beverages of any kind. Halal restrictions can be seen as a modification of the kashrut dietary laws, so many kosher foods are considered halal; especially in the case of meat, which Islam prescribes must be slaughtered in the name of God. Hence, in many places, Muslims used to consume kosher food. However, some foods not considered kosher are considered halal in Islam. With rare exceptions, Christians do not consider the Old Testament's strict food laws
