Walter Martin, as I recall, had Mormon ancestry. Post #38 is interesting, in that the poster appears to believe that orthodox Christian apologetic equates to hate speech.
My impression of Nicea is that Constantine convened it to settle the bickering between the Arians and the trinitarians. The famous ‘one iota of difference’ between homoousian and homoiousian. Like substance, vs same substance. What relevance this debate has for LDS belief isn’t clear to me, as Mormon theology isn’t even in the ballpark of this debate. Jehovah’s Witness theology arguably is related to what was debated at Nicea, LDS doctrine not at all.
Constantine sponsored Nicea, but I doubt that he had much input, so his pernicious character is about as relevant as that of King James, another joker who ended up attaching his name to something significant in church history.
