Rav Eybeschütz again became suspected of harboring secret Sabbatean beliefs because of a dispute that arose concerning the amulets which he was suspected of issuing. It was alleged that these amulets recognized the Messianic claims of Sabbatai Zevi. The controversy started when Rav Yaakov Emden found serious connections between the Kabbalistic and homiletic writings of Rav Eybeschutz with those of the known Sabbatean Judah Leib Prossnitz, whom Rav Eybeschütz knew from his days in Prossnitz. Rabbi Jacob Emden accused him of heresy. The majority of the rabbis in Poland, Moravia, and Bohemia, as well as the leaders of the Three Communities supported Rav Eybeschütz: the accusation was "utterly incredible"—in 1725, Rav Eybeschütz was among the Prague rabbis who excommunicated the Sabbateans. Others suggest that the Rabbis issued this ruling because they feared the repercussions if their leading figure, Rav Eybeschütz, was found to be a Sabbatean. Rabbi Jacob Emden suggests that the rabbis decided against attacking Eybeschutz out of a reluctance to offend his powerful family and a fear of rich supporters of his living in their communities The recent discovery of notarial copies of the actual amulets found in Metz and copying the amulets written by Rav Eyebeschutz support Rav Emden's view that these are Sabbatean writings.
