Square: Hi.
Not sure what you were referring to when you thought I’d implied you or anyone else was a kofer.
As for Ra’avad, as I wrote, his dispute with Rambam was not about what is an ikkar and what is not an ikkar, but whether the mistaken belief that HASHEM has a guf would cause someone to lose their Olam haBa.
Any sources you might have as regards to how Ra’avad (specifically Ra’avad) feels about the CONCEPT of Ikkarim would be appreciated.
(Not only what’s an ikkar and what isn’t, but the IMPLICATIONS of something being an Ikkar — For instance, would philosophical or dogmatic mistakes cause someone to lose their olam haba, as the Rambam maintains?)
