You shall not misuse the name of the Lord your God, for the Lord will not hold anyone guiltless who misuses his name. Exodus 20:7
Growing up attending Baptist Sunday School, I was under the impression that the third commandment referred to cussing. If you said “hell” or “damn”, particularly if “damn” was prefixed by “God”, you were in mortal peril of winding up in the lake of fire yourself. Other four-letter words that didn’t have anything to do with God were also included in the “cussing” category. My original interpretation of “Thou shalt not use the name of the Lord in vain” was “thou shalt not use bad words”.
As I grew older and began to read the Bible for myself, I began to understand that using the Lord’s name in vain had more to do with oath-taking than vocabulary choices. If someone invoked the name of God when making a promise, they had better follow through on their promise, no matter what. For this reason Jephthah, who foolishly promised to offer whatever or whoever first came out to greet him upon his return from a successful military campaign, believed he had to kill his daughter. Apparently the third commandment takes precedence over the sixth, or perhaps child sacrifice isn’t considered murder. Violating an oath made in God’s name was serious business, even if the person didn’t consciously break the promise. Samson was asleep when he got the haircut that caused him to lose his fabled strength. Interesting, women had an escape clause of sorts: their fathers or husbands could veto their vows.
As is usual with written laws, people who are motivated to do so will find a way around them. It’s quite possible to technically obey the law, but disregard its intent. Jesus gave one example of this kind of thinking when he castigated some prominent religious leaders of his time. “Woe to you, blind guides! You say, ‘If anyone swears by the temple, it means nothing; but anyone who swears by the gold of the temple is bound by that oath.’ You blind fools! Which is greater: the gold, or the temple that makes the gold sacred? You also say, ‘If anyone swears by the altar, it means nothing; but anyone who swears by the gift on the altar is bound by that oath.’ You blind men! Which is greater: the gift, or the altar that makes the gift sacred? Therefore, anyone who swears by the altar swears by it and by everything on it. And anyone who swears by the temple swears by it and by the one who dwells in it. And anyone who swears by heaven swears by God’s throne and by the one who sits on it.” If you determine the principle behind the rule, you’ll have a better understanding of how God wants you to behave. “Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’ But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne; or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. And do not swear by your head, for you cannot make even one hair white or black. All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one.” I understand Jesus to be saying that if you make a promise, you ought to keep it. Don’t try to wiggle out of your responsibilities on technicalities.
There’s another way I think humans use the name of God in vain, and I think it is perhaps the most dangerous transgression of all. There are people who self-identify as Christians, but their lives do not reflect evidence of the transformation a person connected to God is undergoing. It is difficult to see the fruits of the Spirit– love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control- in their lives. Sometimes they follow all the rules they demand others follow, and sometimes they don’t. They do not live by the law of love: they do not treat others the way they would want to be treated themselves. They appear to focus more on their own needs and wants than those of others; they are more self-aggrandizing than self- sacrificing. They are quick to judge the behavior of others but slow to see their own faults, let alone try to correct them. They have a tendency to say they are speaking for God, even when they say such demonstrably false things that it is clear that they are not. To put it bluntly, people like that give God a bad name, and if that isn’t “using the name of the Lord in vain” I don’t know what is. They are certainly on Jesus’s bad list, for he says of them, “You shut the door of the kingdom of heaven in people’s faces. You yourselves do not enter, nor will you let those enter who are trying to.” and “You travel over land and sea to win a single convert, and when you have succeeded, you make them twice as much a child of hell as you are.” Whatever the “unforgivable sin” of blasphemy of the Holy Spirit is, this kind of stuff comes perilously close to it.
“Thou shalt not use the name of the Lord in vain” is just as important for those who profess to be on God’s team today as it ever was.
