Some Ans. Questions 1908 by -'Abdu'l-Bahá- 1 Para

Now the question of the good and evil of things is determined by reason or by law. Some believe that it is determined by law; such are the Jews, who, believing all the commandments of the Pentateuch to be absolutely obligatory, regard them as matters of law, not of reason. Thus they say that one of the commandments of the Pentateuch is that it is unlawful to partake of meat and butter together because it is taref, and taref in Hebrew means unclean, as kosher means clean. This, they say, is a question of law and not of reason (266:2)
