Some take it as the height of effrontery that The Church of Jesus Christ of Latter-day Saints refers to its members as "saints." By what justification can Mormons dare to compare themselves to the people traditionally referred to as saints, people who are no longer alive? What makes us think that we can describe ourselves as holy? And what does that suggest about how we think about those who are not Mormons? Do we think that we are the only holy people, with everyone else profane?
Frankly, I don't think most Mormons think much about the meaning of the word saints, though it isn't uncommon for us to use the title to refer to the members of the Church, and we also recognize that the saints of traditional Christianity are another kettle of fish entirely. We rarely, if ever, use the word in the singular, and we never use it as a title. No one is going to refer to Sister Smith as "Saint Smith." And we certainly don't think that being "one of the saints" means that we are necessarily any holier than those who are not one of us.
If asked why we refer to the members of the LDS Church as saints, most of us will probably respond "Because that is what they were called in the first century church," as in Acts 9:32. That's enough reason for most of us: we believe we are a restoration of the Primitive Church; the Primitive Church referred to its members as saints; so we use the same term. But, of course, that answer begs the question. It doesn't tell us why the Primitive Church used the word to describe its members.
There is good reason to believe that to be a saint is to be a holy person. That is at least one meaning of the term. The Greek word translated saint (hagios) means "one devoted to the gods" and indicates purity of character.
Similarly, in the Hebrew Bible, the word for "holy" (qodesh) is used mostly to refer to God, but it can also be used in other ways. Besides God, the Hebrew Bible refers to both people and things as holy (for example, Exodus 3:5, 19:14 [translated "sanctified" in the KJV], and 26:33; Leviticus 19:2; Deuteronomy 33:2-3; and Isaiah 48:2, 62:12, and 64:10). But that meaning isn't enough to explain why God's people are called saints.
In the Hebrew Bible, when used to refer to people or things, the word holy means something like "set apart for holy purposes," always to God and often for purposes of temple ritual. Because holy objects have been set apart, they can be used properly only in certain ways. But it is important to recognize that holiness derives from being set apart, not from the character of the object in question.
