Fearless fighter for the endangered Torah!
BTW, the wicked Gershom Scholem hoped to degrade the rabbi by proving that he cautiously didn’t immediately oppose Shabtai Tzvi. Of course, this in fact proves his integrity and Emuna. Unlike incorrigible skeptics or heretics, Rabbi Sasportes did believe the true redemption would one day come to pass, so he tried to find out if this was it. He wasn’t the type to oppose for the sake of opposing. תתן אמת ליעקב.
