Both the Church of Jesus Christ of Latter Day Saints (the Mormons) and Jehovah’s Witnesses claim to be restored church of Jesus Christ, the only true Christian religion on Earth today. To support their exclusive claims they both appeal to the words of the apostle Peter in John 6:68 in response to a teaching of Jesus that was difficult for them to understand.
However, instead of expressing loyalty to his fellow disciples or to some centralized church authority figure, Peter’s allegiance was to Jesus himself. That both of these groups misuse Peter’s words shows that their desire is to replace Christ with their religious authority as having the words of eternal life.
