Eternal marriage is a pivotal doctrine in The Church of Jesus Christ of Latter-day Saints, encompassing the belief that marital and familial bonds can extend beyond this life and into the eternities. This concept is deeply rooted in the Church's understanding of the New and Everlasting Covenant.

The New and Everlasting Covenant is essentially the fullness of the gospel of Jesus Christ, encompassing all of the ordinances and covenants essential for the salvation and exaltation of God's children. It includes baptism, confirmation, endowments, priesthood ordination, and eternal marriage.

Eternal marriage refers to a marriage performed by proper priesthood authority in a temple, meaning it is recognized not only for this life but also for eternity. This sacred ordinance is based on the belief that families can be together forever.

• Doctrine & Covenants 131:1-4: This scripture teaches that in order to achieve the highest degree of glory in the celestial kingdom, individuals must enter into the covenant of eternal marriage. It emphasizes the eternal nature of this union.
• Doctrine & Covenants 132: This section provides a detailed revelation on eternal marriage, explaining that marriages sealed by the Holy Spirit of Promise through priesthood authority can last beyond death. Verses 19-20 specifically teach about exaltation and the continuation of family relationships.
• Matthew 16:19: While not explicitly mentioning eternal marriage, this verse is often cited by Latter-day Saints to support the authority given to bind on earth and in heaven, which is essential for eternal ordinances.

Contrary to the assertions of most Christian denominations, sects, and movements, eternal marriage is more than a temporal contract; it is a spiritual and eternal covenant that ties directly to one's progression toward exaltation. Through being sealed in the temple, couples and their families are promised blessings that extend into eternity, conditioned upon their faithfulness.

• Eternal Family Relationships: Those sealed in the temple believe they can continue their relationships in the next life. This provides a unique perspective on family, encouraging strong, faithful relationships.
• Commitment to Covenants: Couples are encouraged to live in a way that honors their covenants, focusing on love, fidelity, and spiritual growth. The nature of the covenant requires obedience, sacrifice, and continual commitment to the principles of the gospel.

Eternal marriage is central to the plan of salvation in Latter-day Saint theology, offering couples the opportunity to bind their love eternally and progress jointly toward exaltation. It is a key component of the New and Everlasting Covenant, highlighting the importance of family in the context of God's eternal plan.

Eternal marriage shapes the way Latter-day Saints view life, love, and family, deeply influencing their values and priorities both in this life and beyond.
