Charlie: Rabbi Helfgott is very much on the border (I’m not holding in everything he says but I don’t think he has said any actual Apikorsus; but he is very much at the fringe of non-Apikorsus) and Farber just went way past that.
That “manifesto” quoted contains K’fira in 2 of the Ikkarei Emunah (that the Torah we have today is not the same as the one given to Moshe Rabbeinu and it is K’fira B’torah SheBa’al Peh). Thank you for sharing that. You saved us from doing research for definitive proof that Farber is an Apikores.
