The tenets of our belief were actually not debated at the time, even if you work very hard to dig up a specific outcast opinion and twist it further than intended.
What we accepted was his great work, the Yad, which is Torah-based. We did not accept the Moreh which is philosophy-based. In fact, he was careful to separate the twoand he even contradicts himself at times. There are small exceptions to this and guess what: those areas in the Yad that stem from philosophy are also rejected.
There is something very sickly about this fascinating of Apikursus. There are some places that constantly lecture about the borderline of acceptable belief and beyond, and build towers in the sky of obscure, anomalous shitos — whether or not the Mechaber actually meant to finalize it — dug up from the Sheimos bin and stretched passed capacity. These are of course added onto each other and there you have it: a Mekor for a brand new system.
