Celestial Marriage, as understood in early Mormon doctrine, was a form of marriage, often but not exclusively plural (polygamous), believed to be instituted by divine revelation through Joseph Smith. It was considered a sacred covenant, sealed by priesthood authority, designed to extend beyond death, ensuring eternal family relationships and progression toward godhood, known as exaltation.

Restoration of Ancient Principles

A primary justification for Celestial Marriage was the belief that it represented a restoration of ancient biblical practices and covenants. Early Latter-day Saints taught that God had commanded and blessed plural marriage among patriarchs like Abraham, Isaac, and Jacob, as well as King David, in Old Testament times. Joseph Smith claimed this practice was part of the "fulness of the gospel" that had been lost and was now being restored in the latter days. This restoration was presented as a direct commandment from God, necessary for the establishment of Zion and the preparation for Christ's second coming.

Exaltation and Eternal Kinship

Beyond earthly companionship, Celestial Marriage was fundamentally tied to the concept of eternal progression and exaltation. The doctrine taught that marriage, when performed and sealed by the proper priesthood authority, was not merely "until death do us part" but could endure for "time and all eternity." This eternal union was believed to be essential for individuals to become like God, inheriting all that God has, including the capacity for eternal increase and posterity. Plural marriage, in this view, provided more opportunities for worthy spirits to be born into covenant families and to contribute to the growth of God's kingdom, both on earth and in the eternities.

Sacrifice and Obedience

For many early adherents, particularly Joseph Smith and Brigham Young, Celestial Marriage was presented as a profound test of faith and obedience. It was acknowledged as a difficult and often unpopular command, requiring significant personal sacrifice, emotional fortitude, and public scrutiny. Adherence to this principle, despite societal pressures and personal challenges, was seen as a demonstration of unwavering devotion to God's will. Those who obeyed were promised spiritual blessings, increased knowledge, and greater glory in the afterlife, reinforcing the idea that God asks His people to overcome difficult trials for greater rewards.

Celestial Marriage, particularly its plural form, was a defining characteristic of early Mormonism, shaping its social structure, theological identity, and interactions with wider American society from the 1840s until its official cessation by the mainstream church in the late 19th and early 20th centuries. It was central to the early Saints' understanding of family, divine purpose, and their path to salvation and godhood, distinguishing them significantly from other religious movements of the era.

Was Celestial Marriage always plural marriage?

No, Celestial Marriage referred to any marriage sealed by priesthood authority for eternity, whether monogamous or plural. However, during the period of its practice in early Mormonism, the term often implied the plural form due to its prominence and theological significance at the time.

When was the doctrine of Celestial Marriage introduced?

The doctrine was revealed to Joseph Smith as early as the 1830s, though it was formally recorded as a revelation (now Doctrine and Covenants Section 132) in 1843. Its practice began discreetly in the early 1840s among close associates of Joseph Smith.

Is Celestial Marriage still practiced by the mainstream Church of Jesus Christ of Latter-day Saints?

No, the Church of Jesus Christ of Latter-day Saints officially ceased the practice of plural marriage following the 1890 Manifesto and subsequent statements. While the concept of eternal marriage (monogamous) remains central to its theology, plural marriage is no longer sanctioned or practiced.

What is the difference between Celestial Marriage and civil marriage in this context?

In early Mormon theology, civil marriage was seen as a temporary, earthly contract valid only until death. Celestial Marriage, however, was believed to be a divine covenant, sealed by priesthood authority, that extended beyond death, uniting families for "time and all eternity" and opening the path to exaltation.
