A summary of LDS, Mormon theology
Basic Mormon beliefs are expressed in the "Thirteen Articles of Faith," which were listed by Joseph Smith, the founder of Mormonism when he was asked about the basic beliefs and doctrines of the Latter-Day Saints Church.  Some of the doctrines listed below are unique to LDS thought, while others are shared with Christian denominations. Some are mentioned in the Bible, but most are taught in the other books that are important to the religion, like the Book of Mormon.
Since Mormonism teaches that the LDS church is the modern-day restoration of New Testament Christianity, it is also important to compare LDS beliefs and orthodox Christian beliefs (click link to see a comparison chart). It is also worth noting that many Mormons consider themselves Christians, while many Christians don't consider the LDS church just another denomination due to the theological differences Mormonism has with all other branches of the Christian faith. Below you will find the 13 Articles of Faith; the links provided in the list go to articles that explain the LDS understanding of that topic.
The 13 Articles of Faith in LDS belief
- We believe in God, the Eternal Father, and in His Son, Jesus Christ, and in the Holy Ghost.
- We believe that men will be punished for their own sins, and not for Adam's transgression.
- We believe that through the Atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the Gospel.
- We believe that the first principles and ordinances of the Gospel are: first, Faith in the Lord Jesus Christ; second, Repentance; third, Baptism by immersion for the remission of sins; fourth, Laying on of hands for the gift of the Holy Ghost.
- We believe that a man must be called of God, by prophecy, and by the laying on of hands by those who are in authority, to preach the Gospel and administer in the ordinances thereof.
- We believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists, and so forth.
- We believe in the gift of tongues, prophecy, revelation, visions, healing, interpretation of tongues, and so forth.
- We believe the Bible to be the word of God as far as it is translated correctly; we also believe the Book of Mormon to be the word of God.
- We believe all that God has revealed, all that He does now reveal, and we believe that He will yet reveal many great and important things pertaining to the Kingdom of God.
- We believe in the literal gathering of Israel and in the restoration of the Ten Tribes; that Zion (the New Jerusalem) will be built upon the American continent; that Christ will reign personally upon the earth; and, that the earth will be renewed and receive its paradisiacal glory.
- We claim the privilege of worshiping Almighty God according to the dictates of our own conscience, and allow all men the same privilege, let them worship how, where, or what they may.
- We believe in being subject to kings, presidents, rulers, and magistrates, in obeying, honoring, and sustaining the law.
- We believe in being honest, true, chaste, benevolent, virtuous, and in doing good to all men; indeed, we may say that we follow the admonition of Paul-We believe all things, we hope all things, we have endured many things, and hope to be able to endure all things. If there is anything virtuous, lovely, or of good report or praiseworthy, we seek after these things.
