Is Lust Only Natural?
A multifaith guide to lust.
Christianity generally teaches that lust is sinful. In the New Testament, Jesus says that to lust after a person who is not one's wife is the same as committing adultery. In his Sermon on the Mount, he explains, "You have heard that it was said, 'You shall not commit adultery.' But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart (Matthew 5:27-28)."
Other New Testament writers affirm the idea that sex should only occur within marriage, and that natural impulses outside of marriage only lead to trouble. Paul says in 1 Corinthians, "Now concerning the matters about which you wrote. It is well for a man not to touch a woman. But because of the temptation to immorality, each man should have his own wife and each woman her own husband. The husband should give to his wife her conjugal rights, and likewise the wife to her husband (1 Corinthians 7)."
Further evidence that lust is a sin in Christianity comes from 1 John, where lust is described as being ungodly: "For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world (1 John 2:16)."
Some contemporary Christians understand lust as being sinful only if one acts upon the temptation, not merely if one is lured. But Christian denominations generally teach that lust is wrong. Catholicism considers lust a capital sin. The Catholic Catechism states, "Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes (Verse 2351)."
Similarly, the Church of Jesus Christ of Latter-day Saints warns that a heterosexual marriage is the only proper way to satisfy lust. The Mormon Doctrine & Covenant states, "And he that looketh upon a woman to lust after her shall deny the faith, and shall not have the Spirit; and if he repents not he shall be cast out (42:23)."
