Years ago a modern Darshan came for Shabbos to speak in one of the Shuls in Brisk.
Rav Chaim Solovietchik zt'l, asked him (after hearing part of his Drasha) to step down from the Bima. The Darshan defended himself "All I am doing, is quoting Chazal" he exclaimed. Rav Chaim responded "An animal which was slaughtered properly, salted properly, knives checked properly if it was cooked in a Treif pot renders the meat Treif".
Torah or anything resembling it coming from the mouth or hand of those who are Mevaze Torah or Talmedei Chachamim is 'Treif' VEHAMYVEN YAVIN!!!!
