The Seventh Commandment

Exodus 20:14; Matthew 5:27-28

At the beginning of worship:
Today we’re looking at the 7th Commandment. I can’t think of this commandment without thinking about Jerry. I met him when he started attending Bradley Creek Elementary School in the sixth grade. From the beginning he tried to make himself look good to the teachers. The rowdy group of boys I ran with found this an irritant. 

We had a banquet at the end of the school year. Billy Mason, the principal at Roland Grice Junior High, spoke. He encouraged us to become model students by remembering two passages in the Bible. If we followed these two scriptures they would guide us through our Junior High years and keep us out of his office. He asked if anyone knew which two he referred. 

Some girl up front, the type who always had the right answer, raised her hand. The principal gave her a nod and she nailed it: “Do unto others,” the Golden Rule. The principal smiled and nodded approval. She wouldn’t be seeing the inside of his office.

Then the principal asked for another volunteer and Jerry stood up and boldly proclaimed: “thou shalt not commit adultery.” For a moment the principal remained speechless as we burst into laughter. Not that we knew exactly what adultery entailed, we just knew it wasn’t something we were likely to do in Junior High. 

After gasping for air, the principal tried to regain order. He mumbled something about he hoped we would obey that commandment, too. But he was thinking of a different one. He encouraged us to keep the fifth commandment, to honor our fathers and mothers. In other words, if we acted as if our mothers were watching, we’d have a healthy dose of old fashion guilt and avoid trouble.

Before reading the Scripture:
Last week, as I closed the service, I added a humorous charge before the benediction. Since I had preached on the 6th Commandment, I told you to go out and don’t murder anyone. Then I said, “but you can do better than that. Go out love everyone.” Afterwards, one of the Elders said he couldn’t wait to see my backflip this week. Questioning what he meant, he said that I sent you out to love everyone and this week, I would be qualifying that charge… He’s right because our language uses love in too many ways. Last week, I was referring to love as a verb, not an act. 

Our reading today is another short passage, concerning the 7th Commandment and I will include Jesus’ reinterpretation of this commandment in the Sermon on the Mount. 

Read Exodus 20:14 and Matthew 5:27-28

The seventh commandment is a tough one; we don’t like talking about it. I remember a comic strip; it may have been Frank and Ernest. The Hebrew children gather at Sinai, and a weary Moses comes down the mountain. He tells the crowd below he has some good news and some bad news. He bargained God down to only Ten Commandments.Then he gave the bad news, adultery remained on the list.

Adultery was considered a great sin in the ancient world, even before God gave the Hebrew people the law at Sinai and not just for the Hebrew people. You see this in Genesis, with Abraham and Sarah. Thinking he might be killed, Abraham passed Sarah off as his sister. Sure enough, a  king set his eyes on Sarah, but before he takes her in his harem, he learns the truth through a dream. He feels he has been tricked and is upset for he came close to committing a great sin. 

Literally, the seventh commandment shouldn’t be that hard to obey, even though it’s often broken. But as common of a sin it is, Jesus doesn’t let those of us who have managed to keep the Commandment in a literal sense, off the hook. He pushes the boundaries beyond the physical act and has us internalize it. Like with anger and murder, lust become equivalent to adultery. Unless you are blind and have no touch and smell and hearing, according to Jesus’ interpretation, you’ve probably broken the seventh commandment. Only God really knows, but I suspect most of us have had a few impure thoughts. Such sinfulness is just another reminder of how far the human race has fallen and how totally dependent we are upon God’s grace.

It still amazes me the fuss made over Jimmy Carter’s statement when he ran for President. He admitted to lusting in his heart. What’s surprising is that Jimmy may be one of the few politicians who stopped there and didn’t proceed on to the act itself. Back in the 90s, both our President and Speaker of the House, Clinton and Gingrich, engaged in such actions while pointing the finger at the other. And I won’t go into our current crop of elected adulterers. Unfortunately, those governing us often fail to served as good role models.

As hard as it is to abide, Jesus’ reinterpretation of this commandment is helpful. If you take the seventh commandment literally, you see it applied only to a man who seduced, or was seduced, by a wife or a fiancé of another man. In other words, in a strictly literal sense, this commandment is about protecting the property rights of another man. 

The protection of property rights helps maintain stability in society. As I said last week, commandments six through ten provide us the boundaries within where we can live life abundantly. By internalizing the commandment to include lustful thoughts, Jesus once again goes to the core of the problem. Adultery is a spiritual problem which resides within the heart. 

The Prophets often referred to Israel as an adulterer for chasing after foreign gods. If you remember, the whole premise of the book of Hosea is based upon the analogy of adultery. The prophet is told to take a prostitute as his wife and to love her, even though she remains unfaithful. The people can see, though Hosea grief, how God anguishes over Israel’s unfaithfulness.  

The Christian understanding of marriage is that it’s a three-way covenant. Actually, in some ways, its a four-way covenant. Marriage is not just an agreement between a two people, it also involves God and the rest of the community. We pledge our faithfulness to one another and to our Creator. Committing the act of adultery, because God is involved with our covenant, becomes the same as breaking the first commandment. This is why, if you get into the details of all the laws in Leviticus, you will find that the penalty for adultery in Israel was death. Adultery was as serious as idolatry.  

Keeping the seventh commandment presupposes the keeping of the other commitments. Too often we make an idol out of the family and marriage as the only commitment that matters. But that’s not the case; for us to enjoy life as God intends, we must both keep our marriage vows as well as our commitments to God and honoring those with whom we live in community. Just as with the sixth and eighth commandments, breaking the seventh commandment is a violation which affects the entire community. 

This is why, when I officiate at a wedding, I ask for the commitment from all present to support the couple in the vows they make. And it’s the same reason that in baptism, we ask for the community’s commitment to help the individual grow into Christ. When it comes down to its roots, our faith is not individualistic; it can only be lived out in community.   

I also want to talk briefly about the notion of being single and a Christian. Too often we lift up marriage as the ultimate goal, but we’re probably over reaching by doing that. “The church grows and lives by witness and conversion, not by marriage and family. We don’t have to marry to be faithful to Christ; instead marriage is optional and should be seen more as a calling than some right or a necessity for personal fulfillment.  

Jesus’ reinterpretation of the seventh commandment expands the Law further into a community concern which works to protect women and to awaken men to their responsibilities. As Joy Davidman writes concerning this commandment, Jesus “forgave the adulteress who repented and loved God and denounced the lustful and loveless men who caused her to sin.” In the story of the woman caught in adultery, it is interesting that only the woman was brought before Jesus. We’re left wondering about the man.

For us today, we must consider not just the literal interpretation of the seventh commandment. We should also heed Jesus’ words and the advice from the book of Hebrews, “to hold marriage in honor and to keep the marriage bed undefiled, for God will judge fornicators and adulterers.” There are a bunch of other scripture passages we could consider, especially in Proverbs and in the writings of Paul. By broadening the meaning of this commandment, from a strictly narrow literal interpretation which protected the man’s rights, to a broader interpretation which protects everyone’s rights, shows God’s intention to build healthy communities, one family at a time.  

But then, that was God’s intention all along. If we look back in the second chapter of Genesis, we see that God created the man and woman to help one another and that the two should become one flesh. Adultery is prohibited because it is the knife which cuts through this mystical union and destroys that which God brought together. Honor your marriage vows and look out for one another, in doing so we serve God and one another. Amen.
