In the 3rd grade in the late 1950's in a small Catholic school I was taught that "only in the Catholic Church could one be saved".  We had one Protestant girl in our class whom the rest of the class assumed was damned, leading to taunting and isolation.   One wonders what pain this innocent young girl endured and what damage was inflicted on her self-esteem, and for that matter other Protestant kids, from young Catholics who assumed that everything they heard from the Church was God's truth.

RE: "Of all points of faith, the being of a God is, to my own apprehension, encompassed with most difficulty, and yet borne in upon our minds with most power."   Comprehending God is like discerning the interior of a giant crystal through our own private facet, we see the sharp reflection of our reality  blended with an opaque internal reality.  Every interpretation is necessarily different and the discerner deserves our respect, not judgement which is reserved for the Owner of the crystal.
