From the beginning of creation in the book of Genesis God defines marriage as between one man and one woman. “God created man in his own image… male and female created he them. And God said unto them, Be fruitful, and multiply, and replenish the earth…” (Genesis 1:27 and 28). For Adam and Eve to multiply means God made vaginal intercourse. At the end of chapter one God announces: “And God saw everything that he had made, and, behold, it was very good.” Marriage between a male and a female and vaginal intercourse is good, designed by God.
The following two verses give a man and his wife instructions not to sin. “Wives, submit yourselves unto your own husbands, ® as it is fit in the Lord” (Colossians 3:18). This indicates a man and his wife can do what is unfit and the cross reference to “as it is fit in the Lord” refers one to ® Ephesians 5:3, “But fornication and all uncleanness or covetousness, let it not be once named among you.” Throughout scripture many verses tell a man and his wife there is a form of sexual behavior they should not engage in.
Fornication is clearly defined in Jude 1:7 as being the sex in Sodom and Gomorrah. “Sodom and Gomorrah giving themselves over to fornication…are set forth for an example.” So we can see that God forbids all men and women, including husbands and wives to use their bodies for fornication. This truth is reinforced and made clear in 1 Corinthians 6:13 where it declares, “The body is not made for fornication, but for the Lord.
“But fornication…let it not be once named among you, as becometh saints” (Ephesians 5:3). If you call yourself a Christian you cannot commit fornication even once. Once is all it takes to fall and a fallen person is not an upright person. “Neither let us commit fornication, as some…and fell in one day 23,000” (1 Corinthians 10:8). Adam and Eve began the fall. A fallen person is not a just person. A fallen person is not a holy person. A fallen person is not a Christian. A fallen person is not spiritually alive. They are the dead and need to be raised from the dead.
This same basic, foundational instruction for all humans can be understood when one knows the meaning of the phrase “the fear of the Lord”. In Proverbs 8:13, “The fear of the Lord is to hate evil.” All people should hate evil. “Submitting yourselves one to another in the fear of God” (Ephesians 5:21).” This means no one should commit evil when submitting in a sexual way. Adam and Eve had only two choices in the garden—good or evil. They choose evil. And in Proverbs 14:2 we read, “He that walketh in his uprightness feareth the Lord (hates evil): but he that is perverse in his ways despiseth him.” A person who is upright hates evil. But he that is perverse has fallen, loves evil and hates God. Adam and Eve fell, hated God and loved Satan.
Put the first coming of Jesus in the last days when scripture tells us he will come. Look at the condition of humankind at the end—the majority is evil. Jesus will change the ground for divorce from adultery to fornication. When a spouse who does not believe in oral or anal sex is married to a spouse who does practice such sex the one who does not has grounds to divorce the one who engages in evil acts. Yes, Jesus will change the grounds for divorce “…That Whosoever shall put away his wife, saving for the cause of fornication [porneioa], causeth her to commit adultery [moichao]: and whosoever shall marry her that is divorced committeth adultery [moichao]” (Matthew 5:32). Two different Greek words explain what Jesus means when he tells us, “It was Moses who said adultery is grounds for divorce, but I tell you that fornication (unnatural sex) is the only grounds for divorce.”
There is no fornication in holy matrimony.
