7 Things Mormons Believe about Marriage and Family

When a Mormon couple says they were “sealed” in the temple, many Christians hear, rightly, a spiritual seriousness behind the word—but not always what it means. I remember sitting with a friend who had just returned from a temple wedding and she said, almost breathless, “We’re not just promising to stay married until death. We’re promising to be a family forever.” That one sentence opens a window on seven distinct convictions Latter-day Saints hold about marriage and family.

Why this matters between believers

We may not agree on every doctrinal detail, but understanding how Mormons think about family helps us love our neighbors well. Below are seven core beliefs—each tied to Scripture, church practice, or well-known statements from Latter-day Saint history—and what they look like in real life.

1. Marriage is meant to be eternal

Mormons believe that marriage can—and ideally should—extend beyond the grave. This belief rests on the idea of being sealed in the temple, a rite that binds husband and wife for “time and all eternity,” as stated in Latter-day Saint teaching. The biblical texts Christians share also point to the permanence of the marriage bond:

"So they are no longer two but one flesh. What therefore God has joined together, let not man separate." (Matthew 19:6 ESV)

For many Latter-day Saints, then, marriage is not only a social contract but an eternal relationship with spiritual implications for salvation and family unity.

2. Temple marriage (sealing) is distinct from civil marriage

Civil marriage legally binds two people. In Latter-day Saint practice, a temple sealing performs a separate, sacred function intended to bind couples eternally. Because the temple and its rites occupy a central place in LDS theology, sealings are treated as the highest expression of marital commitment within that tradition.

3. Family is central to God’s plan

The modern Latter-day Saint document widely cited by members, "The Family: A Proclamation to the World" (1995), declares the family to be the fundamental unit of society and central to God’s plan. This emphasis shows up in everyday practices like Family Home Evening (a weekly night set aside for family worship), daily family prayer and scripture study, and concerted efforts at family stability.

If you want to see this lived out practically, consider how many Latter-day Saint families schedule regular home-centered worship. For Christians of other traditions, that discipline is an easy conversation starter about spiritual rhythms at home—see practical ideas in our piece on Christ-centered morning routines.

4. Children are a sacred stewardship

Parenting in Latter-day Saint teaching is spoken of as a divinely given stewardship. Proverbs is quoted in many homes:

"Train up a child in the way he should go; even when he is old he will not depart from it." (Proverbs 22:6 ESV)

LDS emphasis on teaching children gospel truths, early involvement in church programs, and homeschooling or family-centered education choices all flow from the conviction that parents are primarily responsible for a child’s spiritual formation.

5. Chastity before marriage and fidelity after are strongly emphasized

Mormons teach sexual purity before marriage and complete fidelity within marriage. The New Testament words Christians share are cited often in Latter-day Saint teaching:

"For this is the will of God, your sanctification: that you abstain from sexual immorality..." (1 Thessalonians 4:3–4 ESV)

That emphasis shapes dating practices, expectations around courtship, and the rhetoric around what a Christian sexual ethic looks like in modern life.

6. Gender and roles are taught as part of God’s design

Latter-day Saint statements and teachings commonly describe gender as an essential, eternal characteristic and outline complementary roles for men and women in family life. In practice, that often means explicit affirmation of motherhood and fatherhood as divine callings and an encouragement of distinct but interdependent responsibilities in raising children and running households.

That conviction can be a place of both mutual encouragement and disagreement with other Christians. We can seek to understand one another by asking how these convictions shape everyday choices—work, worship, and service to neighbors—rather than debating abstractions.

7. Family history and ordinances for the dead matter

One of the most distinctive Latter-day Saint beliefs is the practice of doing temple ordinances vicariously for deceased ancestors. Members see family history work not merely as genealogy but as a ministry that allows those who did not receive certain gospel ordinances in mortality to be offered those blessings posthumously.

This practice flows from a theological logic about God’s justice and mercy and produces an enormous cultural emphasis on tracing family lines, preserving records, and linking generations together through sacred rites.

Key Takeaways

• Many Latter-day Saints believe marriage can be eternal: temple sealings are intended to bind families beyond death.
• Temple sealings are viewed as a religious complement to civil marriage, not simply a religious formality.
• Family occupies a central place in LDS teaching; practices like Family Home Evening and daily family prayer are common.
• Parenting is treated as a sacred stewardship—early gospel teaching and involvement in church life are emphasized.
• Family history and performing ordinances for ancestors are integral religious practices with deep cultural consequences.

Questions to sit with (and one practical next step)

When you hear Latter-day Saints speak about sealing, eternal families, or vicarious temple work, ask gently: "What does that mean for your daily life?" Most members will answer in terms of routines—prayer, scripture, family night—or commitments at the temple. If you want a small, practical first move to understand a Mormon neighbor better, invite them to tell you what Family Home Evening looks like in their home, or ask about a scripture they read with their children.

If you’re studying Scripture together, try memorizing Genesis 2:24 for a shared starting point:

"Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh." (Genesis 2:24 ESV)

And if your curiosity leans toward culture and community, you might find common ground through shared interests—whether that’s worship music or online communities. See how faith and fellowship show up in other parts of life in our posts on worship music and faith and gaming communities.

A simple habit to try this week

Pick one household practice that matters to them—a weekly family night, a daily verse, or a family altar—and try it for seven days in your own home. Journal what changes: tone? patience? laughter? If you’re honest, you may find that some practices shaped by a different theology still yield spiritual fruit worth borrowing.
