These are a couple of quotes from the book, Teachings of Presidents of the Church: Lorenzo Snow.
"Mormonism, a nickname for the real religion of the Latter-day Saints, does not profess to be a new thing, except to this generation. It proclaims itself as the original plan of salvation, instituted in the heavens before the world was, and revealed from God to man in different ages. That Adam, Enoch, Noah, Abraham, Moses, and other ancient worthies had this religion successively, in a series of dispensations, we as a people, verily believe. ... Mormonism, in short, is the primitive Christian faith restored, the ancient Gospel brought back again--this time to usher in the last dispensation, introduce the Millennium, and wind up the work of redemption as pertaining to this planet."
"This Church will stand, because it is upon a firm basis. It is not from man; it is not from the study of the New Testament or the Old Testament; it is not the result of the learning that we received in colleges nor seminaries, but it has come directly from the Lord. The Lord has shown it to us by the revealing principle of the Holy Spirit of light and every man can receive this same spirit."
