The most emphasized single doctrine contained in the Book of Mormon is that of the divinity of Jesus Christ. It is our belief in Jesus Christ that matters most in this life. The core beliefs of the gospel are as Joseph Smith stated below.
“The fundamental principles of our religion are the testimony of the Apostles and Prophets, concerning Jesus Christ, that He died, was buried, and rose the third day, and ascended into heaven; and all other things which pertain to our religion are only appendages to it” (History of the Church 3:30).
The Book of Mormon stands as another testament to the life and mission of Jesus Christ, past, present and future (3 NE 27:13-20; 3 NE 11:31-40). People worldwide will benefit from a diligent study of the doctrines found in the Book of Mormon. They will find a reaffirmation of many of the teachings that are found in the Bible, and strengthen their faith in Christ. This is why LDS missionaries hand out the Book of Mormon.
Joseph Smith himself made several bold statements regarding the Book of Mormon.
“I told the brethren that the Book of Mormon was the most correct book on earth, and the keystone of our religion, and that a man would get nearer to God by abiding by its precepts, than by any other book.” – Joseph Smith (History of the Church 1:461
“Take away the Book of Mormon and the revelations, and where is our religion? We have none” – Joseph Smith (History of the Church 2:52)
The Church of Jesus Christ of Latter-Day Saints offers the full course meal, not a “cotton candy melt in your mouth” religion, it is a feast. This is the same gospel preached by Christ when he walked the earth. It is the only power able to save men today. That is the “Doctrine of Christ”. We preach a Christ centered message. Bear witness of the truth of the simple gospel that God lives and that Christ lived on earth and is now resurrected, leading the way for all to follow. We preach – faith, repentance, baptism and receipt of the Holy Ghost.
“Who are the individuals that can say that the Gospel of Jesus Christ is true, and that he lives?…There is one class of people, and one only, that live upon the face of the earth, who so know it; and that class of men and women are those that keep his commandments, and do his will; none others can say it. None others can declare with boldness, and emphatically, that Jesus lives, and that his Gospel is true.” Brigham Young (Journal of Discourses, 26 vols. [London: Latter-day Saints’ Book Depot, 1854-1886], 1: 37 – 38.)
