<div dir="ltr"><div>R' Micha Berger asks for a source that Meisis to Kefirah is worse than Meisis to Avodah Zarah.</div>
<div> </div>
<div>That Kefirah is worse than AZ is in the Rambam's Iggeres Hashmad and in the Ibn Ezra to Parshas Yisro. That it is so regarding hating a Meisis, I have some indirect sources based on the above, but it is Mefurash Yotzei Mipi Kohen Gadol in Chofetz Chaim Hilchos Rechilus Klal 1 in Beer Mayim Chaim 9 that Moshe Rabbeinu hated Dasan and Aviram based on hating a Meisis - Al Achas Kamah V'Kamah based on Ki Bikesh L'hadichachah. He is very explicit that the Mitzvah D'Oraysa is not limited to AZ per se.</div>

<div>R' Micha Berger asks:</div>
<div><br>>> Applicability? Who preaches that there is more than one god, but one<br>of them went to Moshe in the midbar, taught him kol haTorah kulah,<br>including TSBP, etc... and you must keep the deRabbanans, etc...<br>
Everyone who incites to AZ also incites to other forms of heresy. <<<br></div>
<div> </div>
<div> I could think of forms of AZ B'shittuf, plus Stam inciting someone to give in to his Taava in the times of Bayis Rishon.<br> <br>Applicability L'maaseh - Daat Emet.</div></div>
