Rabbi Dov Peretz Elkins: An exception to judging favorably
At Shabbat 116a, Rabbi Tarfon says that he would burn the books of heretics, even when they contain God’s name. Rambam, at Hil. Yesode Hatorah 6:8, holds that that applies to a sefer torah written by a Jewish apikoros, but that books written by Akum which contain Divine Names should be buried. Anything involving the burning of books is a fraught matter. The original reference may have been to the Gospels (Evangelion = aven gilyon), and, by many people’s standards, I would be considered an apikoros. In general, we should judge people l’khaf z’khut, but I would make an exception for Jews for Jesus. One can’t go wrong by burying their literature, but I wouldn’t be upset if it were destroyed in some other way.
