“The righteous of all nations have a share in the World to Come.”
Righteous according to whom? Man? There is no righteousness in the man-made noahide laws because they are of men and not of YHWH Elohim & His Messiah.
The FACT is, there was NO oral law given at Mt. Sinai to the Moses & the 70 elders. They received what is written today & that only, so that no man should add to it or take away from what is written. The fact that that command to not add to and not take away from what is written is the only evidence one needs to prove these noahide laws invented by men are just that, an invention birthed out of the imaginations of men, laws that have no one jot or tittle of support from YHWH Elohim & His Messiah.
