Mormons and Catholics are two unique groups that comprise much of America’s religious landscape. Both churches count prominent figures in society among their members. While they have similar goals and a few teachings in common, they have significant differences in terms of doctrines and practices.

The Salt Lake City Temple of the LDS Church, the largest Mormon temple in the world

Mormon” is the common term for members of the Church of Jesus Christ of Latter-Day Saints, or LDS Church. The LDS Church has its roots in the movement started by Joseph Smith in 1830. Smith claimed that a vision of the angel Moroni led him to a set of golden plates that held the teachings of ancient prophets. Smith’s translation of the golden plates, called The Book of Mormon, is an integral part of Mormon doctrine. Other sources of Mormon doctrine include the Bible, Doctrine and Covenants and The Pearl of Great Price. Mormons believe in continuous revelation through LDS prophets, such as the church President, who guides the church through changing times while restoring the original teachings of Christ.

One of these original teachings concerns Christ himself. The LDS Church teaches that Jesus Christ was born in the flesh as the only-begotten son of God the Father. However, he is not of the same substance as God.

They also believe that John the Baptist directly bestowed priesthood upon Joseph Smith. Today, two priesthood divisions exist in Mormonism. The first is the Aaronic priesthood, which consists mostly of young men who have the permission to perform certain ordinances, such as baptism. The second is the Melchizedek priesthood, which is a higher office for older men who move up from the Aaronic order. The President of the LDS Church is a member of the Melchizedek office of Apostle, and Mormons consider him a seer, a prophet and a revelator. He is also God’s spokesperson to the world.

The LDS Church was first headquartered in New York, but moved westward a number of times to Ohio, Missouri and Illinois in order to escape persecution. After Joseph Smith’s death, his successor Brigham Young and his congregation settled in Utah. Mormons now make up the majority of the population in that state, and the LDS Church also has a significant presence in the rest of the United States. Mormon men also go on missions outside the country.

St. Peter’s Basilica in Rome, the largest church in Christianity

Catholic” is a general term for members of the Roman Catholic Church. Catholic tradition claims that Jesus Christ himself proclaimed the apostle Peter as the “rock” upon which the church will be built. After the death and resurrection of Christ, the apostles spread his teachings throughout the Roman Empire. By the year 50 A.D., Christianity was already established in Rome, where tradition holds that Peter became the first bishop. Catholics believe that after the death of the Apostle John, God’s revelation reached its fullness and thus ceased.

The early Christians went through periods of persecution under Roman rule. Their peculiar, secretive rituals aroused suspicion among the rest of the population. However, when the emperor Constantine adopted Christianity in 313 A.D., the persecution stopped. The next few centuries were complicated; theologians argued over topics such as the nature of Christ and the celibacy of priests.

Catholics hold the mainstream Christian belief that God is three “persons”. These are God the Father, God the Son (Jesus Christ) and the Holy Spirit, which are all distinct yet are of the same substance.

Some of the early Christian leaders were married. However, in the 12th century, the Roman Catholic hierarchy decided against ordaining married men as priests or bishops. Traditionally, Catholics consider the bishop of Rome as the direct successor of the apostle Peter. The Bishop of Rome is also known as the Pope, the head of the Church.

The Catholic church in its present form is a result of the Great Schism of 1054 between the eastern and western branches of Christianity. During the 16th century, theological differences resulted in another split within the western church. This split was due to the movement called the Reformation, and the various Protestant sects arose from the movement. Despite the rise of Protestantism, Catholic missionaries from Spain, Portugal and France continued to carry their faith to their respective colonies. As a result, Catholicism is the largest single branch of Christianity.

Mormon vs Catholic


Mormons believe that revelation did not stop with the Bible. Instead, revelation continues in the modern age, starting with the Book of Mormon and continues with revelations to Church apostles. In contrast, Catholics teach that the Bible contains the fullness of revelation. While individuals experience private revelations, they do not replace nor add to what has already been revealed to the prophets and apostles.

Priesthood, Leadership, and Celibacy

The most stark difference between Mormons and Catholics lies in their clergy. Most young Mormon men take on the Aaronic priesthood, and some eventually move up to the Melchizedek priesthood. The highest office of the Melchizedek priesthood, the Apostle, requires that the holder be married. As the President of the LDS church has to be an Apostle himself, he must be married as well.

While Catholic men who wish to become permanent deacons can be married, those who want join the priesthood are required to take a vow of celibacy. The Pope is chosen from a group of bishops, who are also celibate leaders.

The Nature of Christ

Mormons believe that Jesus Christ was the only-begotten son of God the Father and is part of the Godhead, but was born in the flesh and is not of the same substance.

In contrast, Catholics believe that God is three distinct persons – Father, Son and Holy Spirit –that are of one divine substance.
