Father Johnny or the stud husband always says, "Polygamy was taught as a necessity for salvation."
He informs them that marriage, and the comforts and satisfactions of that state, are by divine wisdom prescribed for preventing fornication (v. 2), Porneias—Fornications, all sorts of lawless lust. To avoid these, Let every man, says he, have his own wife, and every woman her own husband; that is, marry, and confine themselves to their own mates. And, when they are married, let each render the other due benevolence (v. 3), consider the disposition and exigency of each other, and render conjugal duty, which is owing to each other. For, as the apostle argues (v. 4), in the married state neither person has power over his own body, but has delivered it into the power of the other, the wife hers into the power of the husband, the husband his into the power of the wife. Note, Polygamy, or the marriage of more persons than one, as well as adultery, must be a breach of marriage-covenants, and a violation of the partner's rights. And therefore they should not defraud one another of the use of their bodies, nor any other of the comforts of the conjugal state, appointed of God for keeping the vessel in sanctification and honour, and preventing the lusts of uncleanness, except it be with mutual consent (v. 5) and for a time only, while they employ themselves in some extraordinary duties of religion, or give themselves to fasting and prayer. Note, Seasons of deep humiliation require abstinence from lawful pleasures. But this separation between husband and wife must not be for a continuance, lest they expose themselves to Satan's temptations, by reason of their incontinence, or inability to contain. Note, Persons expose themselves to great danger by attempting to perform what is above their strength, and at the same time not bound upon them by any law of God. If they abstain from lawful enjoyments, they may be ensnared into unlawful ones. The remedies God hath provided against sinful inclinations are certainly best.
Polygamy was taught as being essential for salvation.[25]: 186  Polygamy was seen as "more important than baptism" and the practice of polygamy was required before the Second Coming of Christ. Brigham Young said that any male member of the church who was commanded to practice polygamy and refused would be damned.[36] Other leaders of the church taught that men who refused to have multiple wives were not obeying God's commandments and that they should step down from their priesthood callings.[37] Church president Joseph F. Smith also spoke about the necessity of practicing polygamy in order to receive salvation.[38] Members of the church in St George, Utah report being taught in the late 1800s that there is no "exaltation" without polygamy.[39] In a church-owned newspaper, an article speculates that men and women who refuse to practice polygamy will have a lesser station in the afterlife.[40]
Polygamy was also explained as being a commandment of God that was received by divine revelation and that polygamy was a part of God's plan
Morality and preventing temptation
An early church leader argued that polygamy has historically been the main form of marriage and that polygamy is the most moral form of marriage.[41]: 44  Polygamy was sometimes explained as a way to prevent men from falling into sexual temptation,[40] while monogamy was immoral and increased the likelihood of sexual temptation
