Nephi tells us our day is the great day of falsehoods. We should expect to see, hear and read "many which shall teach after this manner, false and vain and foolish doctrines, and shall be puffed up in their hearts, and shall seek deep to hide their counsels from the Lord; and their works shall be in the dark." (2 Nephi 28: 9.) There is nothing in this statement which promises that these teachers will be exclusively non-Latter-day Saints. Just because a publication comes from BYU Press does not guarantee Nephi would endorse it. Human weaknesses are such that even the best of efforts by the best people does not guarantee truth. Only one source can guarantee us that, as Nephi teaches. Only the Holy Ghost can assure us we are receiving teachings in harmony with God.
These warnings do us absolutely NO good unless we can see a way to apply them to ourselves and make ourselves better. When we use them to judge, dismiss and belittle other people, we miss the point entirely. The Gospel is not here to justify us in committing a little sin. It is here to school us, discipline us, and bring us into a better relationship with God, and to make us kinder toward each other. Using its sacred teachings and inspired warnings to justify ourselves and look down in our pride at others is not only spiritual malpractice, it is 'Phariseeism.' Religion is not intended to give us a superiority complex. It is to make us better servants.
We should use Nephi's warnings to make us better. We should allow them to challenge, even rebuke us. It is an indication of the Lord's love that He rebukes us. And it is an indication of our own stupidity and shortsightedness when we turn a rebuke aimed at us into condemnation of others, while feeling self-satisfied. Surely we can all agree that is stupid. Yet, astonishingly, we often do just that.
