Joseph,
Please don’t tell me that you’re equating the words of the Tur and the Torah Temimah with the words of God. As great as they were, you can’t honestly tell me that every word of the Tur is the equivalent of words in the Chumash. I don’t think you believe that!
Your story (giving, for the sake of argument that it’s 100% true) only proves that miracles can happen through tzaddikim. It does nothing to prove that their words are free of cultural influences of the times and places in which they lived.
Furthermore, I don’t see how this should be a problem. The Tur and the Torah Temimah weren’t born gedolim. They grew up — just as you and I did. Their lives were influenced by things that happened to them personally, by their culture and the times in which they lived. To argue that they grew up in a cultural vacuum is ridiculous. And to argue that their thought processes, their decisions, the way they lived their lives and their Torah wasn’t affected by their environment is also ridiculous.
Look at it this way — if the Tur grew up in today’s world, would he have been the same person? Let’s grant, for the sake of argument, that he would have had the same level of intelligence, the same personal piety and the same desire to learn. Do you really think that the Tur of this modern-day sage would be the same as the Tur we have now?
