Some people think that because we read the Book of Mormon, we don't read the Bible. That's just not true. It's like saying that we don't eat oranges because we eat apples. Both are good fruit! The Book of Mormon is not a replacement for the Bible. In fact, because the Book of Mormon and the Bible both contain the gospel of Jesus Christ as it was revealed to different civilizations, studying them together can clarify some concepts that are difficult to understand. The Book of Mormon tells us to read the Bible and affirms that its message is true (). And in the Bible, Jesus told His apostles, "Other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd" (). Christ visited these "other sheep" in the Americas after He was resurrected, teaching the same message to the Nephites that He taught to the people of Israel. The Book of Mormon makes it clear that Jesus Christ's message and His atonement are not for one group of people at one time. They are for everyone, everywhere, from the beginning of the earth to the end. Having the Book of Mormon as another testament of Jesus Christ reminds us that He is mindful of every one of us.
If one were to step back from these tangible institutions, the more encompassing themes of faith and doubt play an equally important role in the novel; both of these, in fact, are similar in that they are catalysts for action. Whenever a character proclaims faith in something, that something is pursued. Similarly, when a character doubts something, that is pursued. In the book, doubt can be viewed as a transfer of faith; whenever a character is doubting, they are simply deciding to put their faith in something else. Because the book has no universal standard of morality or value system, there is no black and white. Whatever the character believes in is what they pursue, whether or not it conflicts with the beliefs of another character. As an exemplification of this idea, one can turn to Sue’s final decision to leave Jude. In the final part of the novel, because of a change in her beliefs, Sue discovers that she is committed only to Mr. Phillotson. Because she puts faith in something else, in this case religion (and therefore marriage), she takes action in a completely different direction than before.
