Defending Biblical Marriage in a Culture that Celebrates Same-Sex Relationships

As our culture redefines what God originally created, it is absolutely critical that you understand His original purposes for marriage.

By Dennis Rainey and Bob Lepine

“If two men are in love, and want to declare their commitment, why should we keep them from marrying each other?”

“If two women want to be married, aren’t they upholding the institution of marriage rather than weakening it?”

“If a pair of homosexuals want to marry and provide a home for children who would otherwise be without a family, then how can that be wrong?”

In our ongoing cultural conversation about homosexuality and same-sex marriage, we will continue to have friends and family members who will be asking us questions like these.

Unfortunately, in a culture that increasingly accepts same-sex marriage, many Christians lack the ability to clearly articulate their views on marriage. We often find it difficult to respond to questions or arguments made by those who disagree with us.

If we want to defend the centuries-old understanding of marriage, we should start by looking carefully at what God has to say about it. Marriage is a holy and sacred institution created not by man, but by God. That means that no matter what legislators or justices say, the definition of marriage is not ours to tamper with.

Before laying out a defense for biblical marriage, we need to make two very important points:

First, we in the Christian community need to apologize for the way we have interacted with the LGBTQ community. As those who have been forgiven by God through Christ’s sacrificial death on our behalf, we must exhibit the love of Christ to all men and women. We can stand for the truth and be loving at the same time. This we must do.

Second, our authority to speak to the needs of our nation today is the Word of God. The Scriptures teach that there are absolutes and that there is such a thing as right and wrong.

Truth is never tolerant of a lie. The real battleground around this debate on homosexual marriage begins with the question: Who is your authority? We believe that the timeless truth of Holy Scripture gives us the authoritative blueprints for life. We respect those who wish to deny the truth of Scripture. We would ask for a mutual respect in return.

Reflecting God’s image

Two different passages in the first two chapters of Genesis tell of the purposes God set forth for marriage. The first is Genesis 1:26-28:

Then God said, “Let us make man[a] in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.” So God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.”

The first critical purpose for marriage described here is to mirror God’s image. God made humanity to mirror His image on Planet Earth. The Hebrew word for “mirror” means to reflect God, to magnify, exalt and glorify Him. We are to be God’s representatives to a world that desperately needs to see who He is.

For example, the union of a man and woman reflects the image of God by forming a picture of the intimate relationship between Jesus Christ and His followers. This is a theme that appears throughout the New Testament in passages such as Ephesians 5:22-33. A husband’s love and sacrifice for his wife, for example, are pictures of Christ’s love and sacrifice for the Church.

It’s important to emphasize two things here. First, marriage is not about us; it’s about God. From the beginning our purpose—as individuals and as couples in marriage—is to glorify God. We were created with the capacity to enjoy a relationship with God and to love and serve Him. As Jesus says in Matthew 22:37, the greatest commandment is, “You shall love the Lord your God with all your heart and with all your soul and with all your mind.”

Second, God ties His image to human sexuality. Marking human beings as distinct from the rest of creation, Genesis 1 says “So God created man in his own image, in the image of God he created him; male and female he created them.”

Specifically, our gender differences reflect God as three persons with one essence. In his book, A Christian View of Homosexuality, Glenn Stanton explains:

The members of the Trinity exist in community together at the most intimate level, for while they are Three, they are One. They love one another passionately. Their relationship is exclusive and permanent, i.e., from eternity; there have always been three members and they don’t delete, exchange or add partners. Another important aspect of the Trinity’s relationship is that of “distinguishable peculiarity.” This means that while the members of the Trinity are of the same essence, they are peculiar and distinguishable from one another in their primary characters, much like males and females at the human level. This means that humanity is uniquely fashioned out of these characteristics of the Trinity (relationship, love, intimacy, relational exclusivity, permanence and distinguishable peculiarity) for these things.

Homosexuals have suggested for years that their practice is an acceptable alternative lifestyle. Many claim that their sexual attraction is something they were born with. Some have even suggested that God made them as homosexuals. While the impact of nature vs. nurture can be debated, God makes it clear in Scripture that acting on homosexual attraction is sin.

The practice of homosexuality isn’t a preference or an uncontrollable desire—it’s actually a stark confirmation of a person’s rebellion against the Designer. Romans 1:21-27 tells us that, as humans failed to honor God, their “foolish hearts were darkened” and “they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator … For this reason God gave them up to dishonorable passions. For their women exchanged natural relations for those that are contrary to nature; and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.”

The issue of sexual behavior isn’t a matter of simple preference. Our sexual choices and behavior reflect on the image and glory of God. Our stand against homosexuality is ultimately a stand for the wisdom and perfection of the created design and a choice to honor the Designer.

Multiplying a godly legacy

A second purpose for marriage is to produce children. In Genesis 1:28 when God commands Adam and Eve, “Be fruitful and multiply and fill the earth…” The most obvious aspect of this command is that God designed male and female to join physically and reproduce children. Procreation is an integral part of God’s design for marriage.

In addition, God set up the family as one of his primary institutions (the other being the Church) to tell each succeeding generation about who He is and how they can know Him. God’s original plan called for the home to be a sort of greenhouse—a nurture center where children grow up to learn character, values, and integrity. Psalm 78:7 instructs parents to teach their children to “… set their hope in God and not forget the works of God, but keep his commandments.”

This training in obedience is not only an essential responsibility of the family, but it also is designed to be an outgrowth of the marriage. Research studies make it clear that a stable family with both father and mother provides the best environment for children to thrive, mature, and become responsible citizens of any nation and culture.

Male-male or female-female relationships cannot produce children unless something extraordinary is done to assist them. While it is true that gay couples can raise children, and can adopt needy children, they will not, however, multiply a godly legacy when they are living in rebellion to God. In addition, gay couples cannot model what God designed for a child to experience growing up: a complete picture of a male and female completing one another in the marriage relationship. Children were made by God to be nurtured by the love of a mother and a father from birth.

Mutually completing one another

Another of God’s purposes for marriage is found in Genesis 2:18-24:

Then the Lord God said, “It is not good that the man should be alone; I will make him a helper fit for him.” Now out of the ground the Lord God had formed every beast of the field and every bird of the heavens and brought them to the man to see what he would call them. And whatever the man called every living creature, that was its name. The man gave names to all livestock and to the birds of the heavens and to every beast of the field. But for Adam there was not found a helper fit for him. So the Lord God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh. And the rib that the Lord God had taken from the man he made[d] into a woman and brought her to the man. Then the man said, “This at last is bone of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man.” Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.
