LerntmiTayrah: “As per the gedoilim, anyone who says yechi is clearly an apikoires”
I guess these “gedolim” also hold that rebbi akiva – who said regarding bar kochba ‘Din Hu MAlka Meshicha” – is also an apikores.
and i guess that dvei d’rav yanai ,dvei d’rav chisdai, and dvei d’rav menachem ben chizkiyah are also apikorsim for calling their rebbeim moshiach as it says in Sanhedrin 98b.
