“Solus Christus” which is Latin for “In Christ Alone” is another essential doctrine of the Christian faith that is completely rejected by the Mormon Church. “In Christ Alone” means that Christians trust in Jesus Christ Alone for salvation and do not put faith in any other person to stand between them and God. The Bible teaches at 1 Timothy 2:5, “For there is one God, and one mediator between God and men, the man Christ Jesus.” But the Mormon Church rejects this truth when they add their prophet Joseph Smith to the redemption plan of Christ.
Instead of trusting in Jesus Christ alone, The Mormon Church states in their Ensign article at lds.org entitled, “Joseph Smith among the Prophets” that “…the life of Joseph Smith was in some degree patterned after that of his Master, Jesus Christ. Like his Master, Joseph Smith also shed his blood in order that the final testament, the reestablishment of the new covenant, might be in full effect.” And in this article, the Mormon Church also quotes their prophet Brigham Young who taught: “No man or woman in this dispensation will ever enter into the celestial kingdom of God without the consent of Joseph Smith… every man and woman must have the certificate of Joseph Smith, junior, as a passport to their entrance into the mansion where God and Christ are.”
By adding Joseph Smith to the redemption plan of Christ, Mormonism distorts the Gospel of Christ and cannot be considered Christian.
