The official (or “canonized”) scriptures of the Mormon Church are the Book of Mormon, Doctrine and Covenants, the Pearl of Great Price, and the Bible. These books are referred to as the standard works. Mormons also refer to the messages of the living prophet and the talks given at general conferences as scripture.
“The holy scriptures are the word of God given to us for our salvation. The scriptures are essential in receiving a testimony of Jesus Christ and His gospel. … These sacred records bear testimony of the Savior and lead us to Him.” (Robert D. Hales, “Holy Scriptures: The Power of God unto Our Salvation,” Ensign, November, 2006.)
Biblical Christianity teaches:
The only true Scripture is the Bible. It is God’s Word to His people. It is the only authoritative source for absolute truth. The Bible’s primary message is the gospel. Contained in these words are the message and the power of salvation, full forgiveness, and complete justification of our sins.
