Moroni shares a significant sermon by his father, Mormon, focusing on the essential gospel themes of faith, hope, and charity and how these virtues are essential for spiritual growth and salvation. He highlights the enduring nature of charity, the pure love of Christ, as the greatest virtue one can possess.

In another epistle by Mormon, this one written directly to Moroni, he discusses the erroneous practice of infant baptism. Mormon clarifies that little children are innocent and saved through Christ's atonement, which negates the need for baptism before accountability. 

Mormon writes again to Moroni, and focuses on the dire circumstances of the Nephite people, highlighting their moral decay, loss of love towards all and their thirst for blood and revenge. He talks of the imminent destruction of the people. Mormon encourages Moroni, despite these grievous times, to remain steadfast and faithful in Christ. Mormon pleads that the grace of God abide with his son, Moroni, forever.
