Little Children Are Saved through Christ’s Atonement
Moroni 8:8–9, 11, 19–20
8 Listen to the words of Christ, your Redeemer, your Lord and your God. Behold, I came into the world not to call the righteous but sinners to repentance; the whole need no physician, but they that are sick; wherefore, little children are whole, for they are not capable of committing sin; wherefore the curse of Adam is taken from them in me, that it hath no power over them; and the law of circumcision is done away in me.
9 And after this manner did the Holy Ghost manifest the word of God unto me; wherefore, my beloved son, I know that it is solemn mockery before God, that ye should baptize little children. . . .
11 And their little children need no repentance, neither baptism. Behold, baptism is unto repentance to the fulfilling the commandments unto the remission of sins. . . .
19 Little children cannot repent; wherefore, it is awful wickedness to deny the pure mercies of God unto them, for they are all alive in him because of his mercy.
20 And he that saith that little children need baptism denieth the mercies of Christ, and setteth at naught the atonement of him and the power of his redemption.
The Prophet Joseph Smith said:
“The doctrine of baptizing children, or sprinkling them, or they must welter in hell, is a doctrine not true, not supported in Holy Writ, and is not consistent with the character of God. All children are redeemed by the blood of Jesus Christ, and the moment that children leave this world, they are taken to the bosom of Abraham.”
