Salvation
Christianity
According to the historic, apostolic Christian faith, salvation comes only by the grace of Christ, who "suffered, was crucified, died and was buried, to reconcile his Father to us, and to be a sacrifice, not only for original guilt, but also for actual sins of men."
Mormonism
Mormons also believe that salvation comes through Christ's atoning sacrifice. But they don't believe in "original sin" or in human depravity. Still, Latter-day Saints believe that fallen men and women do need redemption. And while works are a necessary condition, they are insufficient for salvation.
