Is there a difference between Mormon and Latter-Day Saints?
While most members of the Church do not mind being called "Mormons," a more formal way to refer to a person who belongs to the faith is "a Latter-day Saint," or "a member of The Church of Jesus Christ of Latter-day Saints."
How is LDS different from Christianity?
Mormons believe in God the Father, the Son (Christ), and the Holy Ghost existing as three separate individual beings or personages while the Christians regard Christ as immortal and believe in the Trinity. Mormons, like mainstream Christians, also believe that Jesus Christ is the essential path for salvation.
