It seems that the most prominent leaders of "modern-orthodoxy," Haskel Lookstien, Avi Weiss, and Shlomo Riskin, are having a contest to see who can desecrate G-d's name the most. In their own distinct style, each one is leading their followers into the abyss by engaging in one form or another of "interfaith-dialogue." Ironically, all three profess to be students of Rav Soloveitchik, of blessed memory. I can say with 100% certainty that the "Rav" would be tearing kriyah if he saw this. Rav Soloveitchik was always consistent in his stated position that Jews are prohibited from engaging in any form of religious discussion, debate, or dialogue with members of other faith communities. His so-called students are trampling upon their Rebbe's p'sak Halachah.
Shlomo Riskin's love affair with x-tians is absolute madness. It seems that all he does these days is make videos where he fawns all over them. He even sounds like a missionary when he refers to the dead Jew as "rabbi jesus" and uses such ideologically dangerous terms as "branches" (or "grafting" as he did in a previous video) that are laden with x-tian associations. I'll bet the missionaries are having a field day. Videos such as this are surely being translated and distributed by the thousands to misguided Jews, who are now being told by an "orthodox rabbi" that the accursed one (may his bones be crushed to dust!) was also a "rabbi."
