The Facts on the Mormon Church (Harvest House, 1991) p. 33
What is the irreconcilable dilemma for the individual Mormon?
The irreconcilable dilemma for the individual Mormon is that represented by all spiritistic inspiration: contradictory revelation. On some very vital issues, the early Mormon prophets deny and contradict modern Mormon prophets and vice versa.*
Where does this leave the average Mormon? Should he or she accept the Church’s claim that the early prophets were prophets and hence absolutely authoritative? If so, then he or she must charge modern Mormonism (and not Christianity) with apostasy, for the modern Church absolutely denies many of its early divine revelations.
Or should the average Mormon discard the early Mormon prophets as men who received erroneous revelations and were therefore false prophets, since many of their teachings are rejected today by Church leadership? If so, then the entire Mormon Church collapses, for it is based squarely on the divine authority of such men.
In the end, the individual Mormon is faced with two equally unpleasant options. Either 1) the modern Mormon Church is in apostasy and cannot be trusted or 2) the early prophets were deceivers or deceived men and cannot be trusted.
