Great post, ChabadKahanist.
Of course I agree that we are not allowed to derive Jewish Law from the prophecy of anyone other than Moses.
"The Talmud is full of opinions that we don't follow." I keep telling this to some Noahides. The Talmud is not a practical guide for following Torah Law. This is why Jews need the Mishneh Torah and why Gentiles need the Divine Code.
