The third commandment literally prohibits God’s people from making “wrongful use” of the name of God. This need not be restricted to the name “YHWH” (Deut. 5:11), but includes “God,” “Jesus,” “Christ,” and so forth. But what is wrongful use? It includes, of course, disrespectful use in cursing, slandering, and blaspheming. But more significantly, it includes falsely attributing human designs to God. This prohibits us from claiming God’s authority for our own actions and decisions. Regrettably, some Christians seem to believe that following God at work consists primarily of speaking for God on the basis of their individual understanding, rather than working respectfully with others or taking responsibility for their actions. “It is God’s will that…,” or “God is punishing you for…,” are dangerous things to say, and almost never valid when spoken by an individual without the discernment of the community of faith (1 Thess. 5:20-21). In this light, perhaps the traditional Jewish reticence to utter even the English translation “God”—let alone the divine name itself—demonstrates a wisdom Christians often lack. If we were a little more careful about bandying the word God about, perhaps we would be more judicious in claiming to know God’s will, especially as it applies to other people.
The third commandment also reminds us that respecting human names is important to God. The Good Shepherd “calls his own sheep by name” (John 10:3), while warning us that if you call another person “you fool,” then “you will be liable to the hell of fire” (Matt. 5:22). Keeping this in mind, we shouldn’t make wrongful use of other people’s names or call them by disrespectful epithets. We use people’s names wrongfully when we use them to curse, humiliate, oppress, exclude, and defraud. We use people’s names well when we use them to encourage, thank, create solidarity, and welcome. Simply to learn and say someone’s name is a blessing, especially if he or she is often treated as nameless, invisible, or insignificant. Do you know the name of the person who empties your trash can, answers your customer service call, or drives your bus? People’s names are not the very name of the Lord, but they are the names of those made in his image.
