We have discussed various aspects of marriage and complete our study with a look at so called same-sex marriage. Marriage is a covenant. Sexual relations are part of the responsibilities of the marriage covenant. “The husband must fulfill his duty to his wife, and likewise also the wife to her husband” (1 Corinthians 7:3). Would God authorize the marriage of two people when that marriage requires the parties to act contrary to nature? Note Romans 1:26-27. “God gave them over to degrading passions; for their women exchanged the natural function for that which is unnatural, and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error.”
There are two points in particular to note. There are natural sexual relations and unnatural. The natural involves a man and a woman. The unnatural embrace two women, lesbianism, or two men, homosexuality. These relationships entail that which is contrary to what the Westminster Confession and Larger Catechism call “the light of nature.” In part, the light of nature is simply good old common-sense. Homosexual and lesbian relationships run roughshod over common-sense. Question 151 of the Larger Catechism asks: “What are those aggravations that make some sins more heinous than others?” Here is a small piece of the lengthy answer: “Sins receive their aggravations . . . from the nature and quality of the offense: if it be against the . . . light of nature. . . .” Sin is violation of the moral law summarized in the Ten Commandments (1 John 3:4). Sin is aggravated and becomes more heinous when it violates basic common-sense.
Let me illustrate. Paul tells us all things should be done decently and in an orderly manner (1 Corinthians 14:40). Meetings should be conducted with decorum. Christians should never be disorderly. When Christians are discourteous or fail to show proper respect for others, they violate Scripture. They also violate the standard of common-sense. Because this latter standard is not reserved for only Christians, the sin just mentioned is aggravated. So it is with homosexuality and lesbianism. These relationships are so grievous in the sight of God because they insult common-sense. God would never sanction a covenant which requires men or women to act contrary to nature.
This brings us to the second point. Paul says entering into such relationships is great error. Homosexuality and lesbianism are deceptions which plunge men and women into darkness because, to enter such relationships, they must override and overcome the better knowledge of common-sense. When men and women reject the light they have, darkness follows. In the end, the problem is hardness of heart.
Paul puts it this way in Ephesians 4:17-18, “So this I say, and affirm together with the Lord, that you walk no longer just as the Gentiles also walk, in the futility of their mind, being darkened in their understanding, excluded from the life of God because of the ignorance that is in them, because of the hardness of their heart.” Avoid conduct like homosexuality. To justify such activity, you must empty your mind. Darkness follows. Ignorance ensues. Why would you empty your mind of the truth? Paul is clear. The problem is hardness of heart. In the case of homosexuality and lesbianism, the truth disgorged is simple common-sense. What of same sex marriage? God would never sanction a covenant which requires men or women to act contrary to nature.
