For someone who does not accept the idea of divine authorship or inspiration of the Biblical text (like me), the question is: <i>why</i> is it written into the Bible as a divine commandment? Where did this religious law come from? A lot of the laws in that text have some sort of systematic&#x2F;philosophical justification for them, however alien that justification might be to modern ears, so what is it for the Kashrut laws?
