Mormon teaches Moroni about infant baptism, the Atonement, and salvation of little children.

Moroni 8 contains an epistle from Mormon to his son, Moroni, addressing the incorrect practice of infant baptism. Mormon clarifies that little children are alive in Christ through the Atonement and are not capable of committing sin, thus having no need for baptism. He emphasizes that baptizing infants is a solemn mockery before God and that true baptism comes by faith and repentance for those accountable.
