Mormon churches do not have any crosses, either outside or inside. Mormons do not wear cross necklaces or display it in their homes. They say they don’t use it because it is a symbol of his death.
DOES ANYONE IN THE CHURCH WEAR THE CROSS?
Interestingly, “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” (True to the Faith, p. 46). This is a fact Christian military personal should be aware of so there are no misunderstandings when they look for a Christian chaplain.
A common practice for those who leave Mormonism and discover biblical Christianity is to wear a cross. They find beauty in the cross because now they understand grace.
