Greetings. I am a Catholic, but have been having some troubles with some Catholic doctrines, which has caused me to research other Christian denominations. Although I have been able to locate plausible rebuttals of many Catholic positions, there is one which I am having some trouble finding thorough opposition to. Please accept my questions at face value as I am seeking truth and understanding, not seeking argument. I am presently reading the book The Inevitable Apostasy by Tad R. Callister, and am finding it quite enlightening and helpful. In the book, he points out that LDS theology is opposed to the Catholic doctrine of transubstantiation. I was hoping for him to discuss within his book one of the main proof-texts for what Catholics call The Real Presence: John 6:48-69, but he does not. In these verses, Christ tells those listening that they must eat his flesh and drink his blood. His statement is met with shocked disbelief. Even many of his disciples said to themselves, “This is an hard saying; who can hear it?” – John 6:60. At this point, many turn away from Christ and no longer follow him. (John 6:66) At other points, we see Christ teach using parables, and we see him explain the parable afterwards. Yet in this instance, Christ simply watches many disciples walk away from him after hearing him say this. He does not call them back to explain, nor does he chastise them for mistakenly believing that he meant his words literally. He simply allows them to walk away. “From that time many of his disciples went back, and walked no more with him.” – John 6:66. This seems to indicate to me that those who went away did indeed understand Christ correctly – that he was putting forth the teaching that they needed to literally eat his flesh and drink his blood – abhorrent practices to the Jews of the time. Can you help me to understand what was going on here if not the plain meanings of the words? And why Christ would seemingly allow many to lose their salvation over a seeming misunderstanding of his words? Please share with me the official LDS teachings on these verses and this topic. Thank you for helping me to understand.
