In the title page of the Book of Mormon, we read, "...if there are faults they are the mistakes of men; wherefore, condemn not the things of God."
Lastly, we read the words of Moroni shortly after he took over his father's record: "Condemn me not because of mine imperfection, neither my father, because of his imperfection, neither them who have written before him ... we have written this record according to our knowledge, in the characters which are called among us the reformed Egyptian, ... and if we could have written in Hebrew, behold, ye would have had no imperfection in our record" (Mormon 9:30-31).
As emphasized repeatedly in this series, anything with which man is involved -- even if directed by God -- will be imperfect, fallible and, to some degree, errant. Neither ancient nor modern prophets were, or are, perfect, and the scriptures they've produced will likewise fall short of inerrancy. Fallible human prophets and errant scripture can still lead us to God despite any imperfections.
