Wow, it’s the Mormon answer.
I am no Mormon theologian, but I do know that the Mormons believe that the whole Christian Church apostasized sometime rather shortly after the death of the last Apostle, went through 1800 years of sheer heresy, only to have the Church restored in the 1800's by none other than that tireless religious entrepreneur, Joseph Smith.
They have nothing whatsoever to do with 20 centuries of sensus fidei in the 2nd, 3rd, 4th. 5th centuries, right up to the present ("continuity") plus the theological reflection by Fathers and Doctors of the Church.
This is not just a slight difference between Catholicism and Mormonism: in this respect, they are polar opposites upon the very foundations of the Faith.
It is hard to communicate with a person who refuses to consult primary sources even when they are only a mouse-click or a finger-tap away; who demands primary-school answers to matters of great complexity; and who draws conclusions diametrically opposed to the evidence.
This is no dialogue. It is a dual monologue on two parallel tracks which never meet. To be frank, I continue to put forth the necessary effort only for the sake of the lurkers.
