The claim today is that the Torah is outdated, old fashioned and not relevant to today's society. In fact this past summer, the father of one of the Christian chaplain's told me that his son, who is in one of the prominent Protestant seminaries, is studying which laws from Leviticus are no longer observed, and what determines their invalidity in the modern era. He then asked me the Jewish view on the Book of Leviticus. I told him, the Orthodox view is that everything said in VaYikra is valid. However certain laws, for instance, the Sacrifices, can not be performed and practiced in the modern era because the Beis HaMikdash is no longer standing.
People today say that society has changed.
Things are different now than they used to be 3000-4000 years ago. In a sense, that's true. However, man has not changed at all. Life circumstances have changed, for instance, technology, democracy, but human nature has not changed at all. There is more danger, war, conflict and hate in the world today than there was before the Gulf War and the formation of the 'new world era'.
