Knowing and Living the Christian Sex Ethic
For the church to play her part in reforming the sexual morals of our nation, she must know and live the Christian sex ethic; she must display the beauty of godly living and the greater joy that is derived from it than from the fleeting pleasures of sin. In brief, Christians have to make a case that the godly sex life is the good sex life.
Contrary to what our cultures behavior suggests, sex is not a commodity to be bartered or sold to satisfy a merely physical appetite. Sex is, as Timothy Keller says, “a collaborative covenant renewal ceremony in which two covenant partners confirm, celebrate, and deepen their one flesh union.” Sex is a sacred act; one that as Daniel Heimbach writes, “[wraps] physical pleasure, emotional satisfaction, psychological fulfillment, and spiritual meaning into one complex relationship.”
And God’s guidelines (i.e. his ethical boundaries) for sex are pretty clear: In Genesis 2:24 we read, “A man shall leave his father and mother and be united to his wife, and the two become one flesh.” And in Hebrews 13:4 we read, “Marriage should be honored by all, and the marriage bed kept pure.” So, according to the Bible, this particular activity was designed for operation strictly within the confines of marriage, which God defines as a lifelong, one-man, one-woman, monogamous relationship.
But why does God restrict sex to marriage? In order to live the Christian sex ethic and be able to rationally persuade others of its superiority, it helps to have a strong understanding of the logic behind God’s law:
First, if sex, by definition, is a covenant consummating and renewing ceremony between two covenant partners, then sex cannot fulfill its purpose if there is no covenant to consummate or renew. The whole meaning of the event would be lost, as sex presupposes that two people have already become one (legally and relationally) in the eyes of God and the community.
As Keller explains, sex is a way of saying to another person, “I belong completely, exclusively, and permanently to you.” Outside the context of marriage, you just can’t say that, at least not honestly. Outside of marriage, sex says something not quite so romantic. Outside of marriage, sex is a way of saying, “I belong partially, openly, and temporarily to you.” Premarital and extramarital sex force you into committing what we might call a contradiction of non-verbal communication.
Second, if you look closely in Genesis you will see that complementary pairs (e.g. heaven and earth; man and woman, etc.) are woven into the very fabric, structure, and constitution of creation. “Humans are body and soul, in two genders,” as J.I. Packer writes. Which means that God’s will for men and women with regard to sex and marriage is not arbitrary but rooted in the very nature of humanity.
Therefore, sex outside of marriage (the supporting foundation and framework for sex) will always cause some measure of bodily, psychological, and relational harm—because it goes against the grain of God’s design. Outside of marriage, sex can never provide the level of pleasure and satisfaction that are only possible inside the boundaries of marriage.
In fact, according to the Wheatley Institution Global Family and Gender Survey, “highly religious, gender traditional couples” are the most satisfied couples. And according to the General Social Survey, “religious men who do not use porn” are the happiest husbands. Explaining the significance of the data, Stone writes:
Protestant sexual norms are highly conducive to individual and marital happiness. Our…lifestyle model of chastity until marriage and commitment within marriage is, in fact, the most strongly happiness-associated lifestyle in America today.
Third, in addition to eroding joy, sex outside the context of marriage also hinders cultural development—specifically with regard to making and raising children. Obviously, a homosexual relationship can’t contribute to cultural development in this way, as the nature of the relationship eliminates the possibility of procreation. But heterosexual sex outside of marriage also hinders cultural development, as it neglects to establish the appropriate environment for raising children (and promotes conditions conducive to an abortion culture and mindset).[21] As Jane Anderson notes, “Nearly three decades of research evaluating the impact of family structure on the health and well-being of children demonstrates that children living with their married, biological parents consistently have better physical, emotional, and academic well-being.”
It is, without a doubt, in our and others’ best interest to live the Christian sex ethic.
Hope for a Sexual Reformation
Our culture, like the Greco-Roman culture, is rife with sexual immorality. Sadly, as recent events constantly remind us, this sexual immorality too often finds a home in the church as well. However, if Christianity can establish a plausible sexual counter-culture — one that elevates women, dignifies marriage, and redeems male sexuality — then perhaps like in Rome, the effect can be a slow, but efficacious, reform of sexual ethics in broader American society.
