In some ways, the teachings of Biblical Christianity on sexual ethics are well known. Most people know what the churches (at least, the Christian denominations that resist the liberalization of same-sex marriage and abortion laws) teach. In God’s image, men and women are made for love. The Bible says:
So God created man in his own image, in the image of God created he him; male and female created he them. (Gn 1: 27 KJV)
All that authentic biblical Christianity teaches about sexuality and human love is that God, who is love, created male and female in His image to share His infinite love and reflect His infinite love in the world and in their lives. Both man and woman receive the capacity to be in a relationship with God who created them in His image – and with each other. He has also given them the power to cooperate with Him to create new life – procreation.
Male and female are the twofold expression of human nature, different from one another in terms of their bodies but they are created for each other. They are created to give of themselves to each other. Both men and women are equally important in the ways they relate to each other and, above all, equal in dignity. Their differences complement each other and allow each one to relate to one another in profoundly personal ways. Both male and female are made for relationship and called to love like God with responsibility, faithfulness, trust, mercy, forgiveness, and generosity. Every person created in the image of God has great dignity.
Both man and woman – with equal personal dignity, their body and soul, human body and sexuality – are integral part of God’s design. It is essential to accept one’s body, to value it, to care for it, respect its full meaning, and fulfill its true purpose. In doing so, each one can joyfully accept each other’s specific gift of mutual love.
One ought to treat his/her body as the temple of God. The Bible says:
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are. (1 Corinthians 3:16-17 KJV)
What? Know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s. (1 Corinthians 6:19-20 KJV)
There is nothing dirty or shameful about the human body and our sexuality because God created us this way. Everyone should acknowledge and accept his/her sexual identity. We would do no better not to diminish our sexuality but to thank and honor God for His plans for our lives.
Having known the truth about our dignity as a human person, we have the moral, social and spiritual obligation to resist sexual perversion, especially in this generation of sexual confusion. True Christians know in their heart, mind, and soul it is never morally right to commit unnatural sexual acts, one of the most perverse being the act of oral sex. The topic of oral sex and sexual perversion, in general, is tackled in the book of Marilyn Taplin titled A Law from Eden: Solving the Mystery of the Original Sin.
Moreover, it is an abomination to commit sex outside of marriage, i.e., to fornicate or commit adultery, to masturbate, to commit sodomy, i.e., have oral or anal intercourse, whether with a person of the opposite or the same sex, to commit pedophilia, to have sex with animals, and other forms of sexual perversion.
True Christians know in their heart, mind, and soul recognize sex as a marvelous gift from God and is to be honored in marriage. The Bible says:
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge. (Hebrews 13:4 KJV)
Throughout the Bible, Christians are warned against sexual perversion and are exhorted to resist sexual immorality.
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. (1 Corinthians 6:9-10 KJV)
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. (1 Corinthians 6:18 KJV)
For this is the will of God, even your sanctification, that ye should abstain from fornication: That every one of you should know how to possess his vessel in sanctification and honour; Not in the lust of concupiscence, even as the Gentiles which know not God. (1 Thessalonians 4:3-5 KJV)
In the face of many challenges to the biblical Christian notion of sexuality, everyone is to remind themselves that they are made in the image of God and are called to honor their body – the temple of God – with reverence.
