As one of the essential requirements of faith, Mormons view baptism as the first of several saving ordinances of the gospel. When baptized, Mormons enter into a covenant with Heavenly Father. God has done His part. Now it is up to Mormons to do their part by striving to be obedient to the Lord’s commands, keeping all of His covenants, and enduring to the end in following the example of Jesus Christ.
“When you were baptized, you entered into a covenant with God. You promised to take upon yourself the name of Jesus Christ, keep His commandments, and serve Him to the end. You renew this covenant each time you partake of the sacrament.” (True to the Faith, p. 23)
Mormons are baptized by immersion either at the age of eight or when converted to the teachings of Mormonism. “Immersion is symbolic of the death of a person’s sinful life and the rebirth into a spiritual life, dedicated to the service of God and His children.” (True to the Faith, p. 22) Through baptism, a Mormon is “born again” into a new life of service, receives the “constant companionship” of the Holy Ghost, and begins the process of receiving the forgiveness of sins. These baptismal blessings are all dependent on a Mormon’s worthiness.
Even though a Mormon is baptized with water “in the name of the Father, and of the Son, and of the Holy Ghost,” it is not a valid Christian baptism since the LDS church does not believe in the Triune God.
Biblical Christianity teaches:
God instituted baptism as a means for a person to receive the benefits of what Christ did for us. While Mormonism emphasizes their covenant promises in baptism and how its blessings are received through obedience, the Bible emphasizes the immediate blessings we receive now. The blessings of baptism include the complete forgiveness of sins (Acts 2:38), a new spiritual life (Romans 6:4), and eternal salvation (1 Peter 3:21).
