Q: Is the Church a rich church? Some people occasionally describe the Church as a prosperous organization. However, the strength of the Church cannot be measured by its financial holdings or real estate assets. As President Gordon B. Hinckley said, “When all is said and done, the only real wealth of the Church is in the faith of its people” (“The State of the Church,” 54). The relative current prosperity of the Church only reflects the faith of its members in observing the law of tithing and other guiding principles such as provident living and self-reliance. It is based on the Lord’s promise that “inasmuch as ye shall keep my commandments ye shall prosper in the land.” This promise appears in 18 verses of the Book of Mormon, and Latter-day Saints believe it continues to apply today.
