Day 6 — Moroni 8:1–17 – Do infants need to be baptized?

Scripture Focus: Moroni 8:1–17

LDS Quote

“The Book of Mormon teaches true doctrine to dispel false religious traditions—such as the erroneous practice of performing infant baptisms. The Book of Mormon gives purpose to life by urging us to ponder the potential of eternal life and ‘never-ending happiness.’” — Russell M. Nelson

Mormon's doctrine on baptism

The teaching of child baptism is strongly rejected in this chapter. Mormon writes to his son Moroni specifically on this issue, teaching that children cannot sin and are spiritually whole. He argues that they are not capable of committing sin and that “the curse of Adam is taken from them” in Christ. He presents children as alive in Christ and therefore not in need of baptism.

Mormon reasons that if children could not be saved without baptism, God would be partial and unjust — showing favoritism. His argument follows that to condemn children for lack of baptism would contradict God’s mercy and justice. Therefore, because they are whole and alive in Christ, they are saved regardless of baptism.

The chapter frames infant baptism not merely as unnecessary, but as a misunderstanding of God’s character. Justice, in Mormon’s argument, requires that children be exempt from both guilt and ordinance.

Baptism in Biblical Continuity

The Church and many of her practices in the New Testament did not appear in isolation. They stand in continuity with what God had already revealed to Israel. The feasts, the sacrifices, the temple, the priesthood, and the rituals were not random religious customs; they formed part of a divinely ordered pattern. Paul writes that these things were “a shadow of things to come, but the substance is Christ” (Colossians 2:17). They pointed forward to fulfilment.

Christ Himself declared that He did not come to abolish the Law, but to fulfil it (Matthew 5:17). He is not a contradiction of Torah; He is its goal and completion. The early Jewish believers did not see Jesus as a departure from Moses, but as the promised fulfillment of what Moses and the Prophets had anticipated. Had He performed signs and wonders yet led Israel toward another god, He would have fallen under the warning of Deuteronomy 13 — a prophet whose miracles mask rebellion against the Lord. Instead, Jesus revealed the fullness of the God of Israel and confirmed the covenant promises rather than overturning them.

For this reason, dividing Scripture into “Old” and “New” Testaments can sometimes obscure the unity of God’s redemptive plan. The Bible is one unfolding story — one covenantal narrative — revealing the holiness of God, the failure of man, and the promise of redemption.

It is within this continuity that we must understand baptism. Long before John stood in the Jordan proclaiming repentance, Israel already knew the language of water and cleansing. In the Old Testament, God commanded various washings as part of covenant life. The Hebrew term mikveh (“gathering of water,” cf. Genesis 1:10) came to describe pools used for ritual purification. Under the Law of Moses, washing was required after bodily impurities (Leviticus 15:5–13), before priestly service (Exodus 30:17–21; 40:12–15), after contact with death (Numbers 19:11–19), and in preparation for sacred duties such as the Day of Atonement (Leviticus 16:4, 24). These immersions were not about physical cleanliness but covenant holiness. They restored ceremonial standing within Israel’s covenant life.

This was not abstract theology; it was visible architecture. In Israel today, when walking around the Davidson Center archaeological park just outside the Temple Mount — where the First and Second Temples once stood and where, according to biblical prophecy, a third and later a fourth temple will stand — numerous excavated mikvahs surround the southern approach. Worshippers would descend on one side, immerse for purification, and then ascend the opposite steps before entering the temple precincts. The design itself preached holiness.

There is no fixed number of these immersion pools in that area, but they are abundant. One of the most well-known large ritual pools from the Second Temple period is the Pool of Siloam. With such extensive water systems already present in Jerusalem, it is not difficult to understand how three thousand people could be baptized on the day of Shavuot (Acts 2:41). The infrastructure for mass immersion already existed. Baptism emerged within an already established pattern of covenantal washing.

History and Biblical Evaluation of Infant Baptism

There has long been debate concerning when infant baptism emerged within Christian communities. The earliest Christian writings outside the New Testament, such as the Didache, describe baptism in connection with instruction and preparation but do not mention infants. By the late second century, Irenaeus refers to Christ sanctifying all ages. In the early third century, Tertullian argues that baptism should be delayed for children until they can understand and request it, demonstrating that the practice was present but debated. Origen later claimed apostolic origin for infant baptism, and by the mid-third century Cyprian affirmed baptizing infants without delay. By the fourth century the practice had become widespread throughout much of the Christian world.

The historical record shows development, not an explicit apostolic command.

When we turn to Scripture, baptism is consistently connected with repentance and belief (Acts 2:38–41; Acts 8:12; Acts 18:8). Those baptized are described as hearing the message, receiving it, and responding.

This is not merely an argument from silence. The Epistle to the Hebrews was written to Jewish believers who were wrestling with how the Mosaic covenant related to the new covenant in Christ. The author carefully explains the fulfillment and obsolescence of the priesthood, sacrifices, temple, and ceremonial law (Hebrews 7–10). These were central covenantal markers for Jewish identity. If baptism were intended as a direct covenantal replacement for circumcision administered to infants, such a profound transition would likely appear in a letter devoted to explaining covenant transformation. Yet Hebrews does not present baptism as a continuation of infant circumcision.

The New Testament emphasis is not on transferring an outward sign but on inward transformation — the circumcision of the heart. Paul writes, “He is not a Jew who is one outwardly… but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit” (Romans 2:28–29). In Colossians 2:11–12 he describes believers being circumcised with a circumcision made without hands — a spiritual reality accomplished by Christ.

Even under the Mosaic covenant, physical descent from Abraham and participation in circumcision did not guarantee salvation. John the Baptist warned the people of Israel: “Do not presume to say to yourselves, ‘We have Abraham as our father’” (Matthew 3:9). Covenant sign did not equal covenant faith.

For this reason, we do not baptize infants. Baptism in the New Testament follows conscious repentance and faith. It is not an automatic sign applied at birth, nor a mechanical transfer of covenant status. The sign follows the response of faith, not biological birth.

Many Christian traditions teach that water baptism itself washes away sin. Yet Scripture consistently attributes the cleansing of sin not to water, but to the blood of Christ and the renewing work of the Holy Spirit. “The blood of Jesus Christ His Son cleanses us from all sin” (1 John 1:7). We are saved “not by works of righteousness which we have done, but according to His mercy, through the washing of regeneration and renewing of the Holy Spirit” (Titus 3:5). Water does not remove guilt before God; Christ does. Baptism bears witness to cleansing accomplished by Him — it does not create that cleansing.

The Bible's teaching is worth considering

If humanity were judged only on the basis that Adam merely set a sinful example rather than that his fall affected the human race, then the result would move toward what later theology called Pelagianism. That view suggests that human beings are born morally neutral and simply imitate the sins of those who came before them. Yet the Scriptures consistently teach something deeper: mankind is enslaved to a sinful nature and cannot free itself apart from the redeeming work of Christ.

If Adam’s disobedience affected only himself, then humanity’s universal corruption would require another explanation. The witness of Scripture is that the fall damaged God’s creation. Physical death entered the world because of sin, and spiritual death is the wages of sin. Humanity lives under the shadow of that brokenness. Without the redemption purchased through the blood of Christ, mankind is hopeless.

Consider Cain, the first child born after the fall. If he were born into a completely uncorrupted condition yet chose murder on his own, the depravity of mankind would no longer be traced to Adam’s disobedience but instead to a flawed creation. The biblical story instead presents a world already wounded by sin, a world in which rebellion spreads quickly through the human race.

The gospel proclaims the opposite direction. Where Adam’s disobedience brought death, Christ’s obedience brings life. Jesus willingly chose obedience even unto death on the cross, and through that obedience the penalty of sin is overcome.

King David gives one of the clearest reflections on human sinfulness. After falling into adultery and murder, he cried out in repentance:

“Have mercy on me, O God, because of your unfailing love.Because of your great compassion, blot out the stain of my sins.Wash me clean from my guilt. Purify me from my sin.For I recognize my rebellion; it haunts me day and night.Against you, and you alone, have I sinned; I have done what is evil in your sight. You will be proved right in what you say, and your judgment against me is just.For I was born a sinner—yes, from the moment my mother conceived me.”— Psalm 51:1–5 (NLT)

David recognized that sin was not merely imitation but part of humanity’s fallen condition.

Yet Scripture also teaches that God is perfectly just and perfectly merciful. When God revealed His character to Moses, He declared Himself to be:

“Yahweh, Yahweh Elohim, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth.”— Exodus 34:6 (LSB)

The fear often raised is that if infants are not baptized they would therefore be condemned. But such reasoning appeals more to human emotion than to the revealed character of God.

Scripture itself provides a profound moment that speaks into this question through the life of David. After David’s sin with Bathsheba and the murder of Uriah, a child was conceived. As part of the judgment for David’s sin, the child became ill and died. David fasted and prayed while the child lived, hoping for mercy. But once the child died, David rose and worshiped God. When his servants questioned him, David said:

“While the child was still alive, I fasted and wept; for I said, ‘Who knows, Yahweh may be gracious to me, that the child may live.’ But now he has died; why should I fast? Can I bring him back again? I will go to him, but he will not return to me.”— 2 Samuel 12:22–23 (LSB)

David rested in the knowledge that the judgment fell upon him, not upon the child. His confidence was that he would one day go to his child.

For this reason, the Church can affirm both truths taught in Scripture: humanity is fallen in Adam, yet God is perfectly just. Infants are not condemned because they lack a ritual ordinance, nor because they are naturally whole, but because the God who judges the earth does so with perfect wisdom, justice, and mercy.

David trusted the character of God, and so can we. The Judge of all the earth will always do what is right. I know that God is not a partial God, neither a changeable being, but one who is unchangeable from all eternity to all eternity. Therefore we can rest in the certainty that His judgments are always righteous, and His mercy is never in conflict with His justice.
