The cross is used in many Christian churches as a symbol of the Savior's death and Resurrection and as a sincere expression of faith. As members of The Church of Jesus Christ of Latter-day Saints, we also remember with reverence the suffering of the Savior. But because the Savior lives, we do not use the symbol of His death as the symbol of our faith.
Our lives must be the expression of our faith. When we are baptized and confirmed, we covenant to take upon ourselves the name of Jesus Christ. The way we live our lives should demonstrate our love for the Savior and His work.
The only members of the Church who wear the symbol of the cross are Latter-day Saint chaplains, who wear it on their military uniforms to show that they are Christian chaplains.
