F. Israel’s Positive Responsibility
The third commandment can be understood best by examining Israel’s positive responsibilities towards God’s name and reputation. Israel was to be a light to the nations.[1] Just prior to the Decalogue Israel was said to be a kingdom of priests and a people who were specially set apart.[2] Deuteronomy 28:9-10 states, “the Lord will establish you as a people holy to himself, as he has sworn to you, if you keep the commandments of the Lord your God and walk in his ways. And all the peoples of the earth shall see that you are called by the name of the Lord, and they shall be afraid of you” (ESV). Israel is called to be a unique people and represent God to the nations around them. Israel is called by God’s name, so that the reputation of Yahweh is linked with the reputation of Israel. Israel was thus primarily responsible to bring praise, glory and honor the character and reputation of God in the world. They were to accomplish this by living according to the prescriptions He gave them at Sinai. Bearing God’s name then is not limited to false oaths, or to syncretistic worship practices. Rather the third command states that Israel is not to bear God’s name in a manner that falsely represents Him to the world.
This understanding of the third commandment is connected to other key theological themes in the Old Testament. First, it is tied to image theology of Genesis 1-3 and Genesis 9. Man is seen to be responsible to God as his vice-regent on earth. Israel through their keeping of the commandments is to be the image of God par excellence in the world. Second, it is tied to the call of Abraham to be the agent through whom blessing would come (Gen 12). By entering into this covenant with Yahweh, Israel has assumed the responsibility of representing Yahweh to the world. They are to be His agent of blessing and so must bear His name in accordance with His character. Third, it is tied to the suzerain-vassal treaty made with Abraham (Gen 15). Israel as God’s vassal has an obligation to represent well their suzerain. Representing the divine name in such a way that it is viewed as worthless or false would bring dishonor and scorn to God.
F. Divine Defense of the Name
What is at stake in the third commandment is then the maligning of the character and reputation of God through the misuse of His name and misrepresentation of His character. The warning at the end of the command strengthens this understanding. The command states, “for the Lord will not hold him guiltless who takes his name in vain” (ESV). The essence of the warning in this command is that God will judge those who malign His name in any way. The divine defense of the name is stated clearly as a warning against behaving in any way that might bring dishonor to the name of God and thus to the character and reputation of God.
Conclusion
The third commandment is fundamentally a prohibition of misrepresenting God. This misrepresentation of God could come in any number of ways. It could include flippant and irreverent speech about God, thus revealing a lack of respect for Him and giving the world a low view of a great God. The command would also prohibit swearing falsely by God’s name, thus making God appear to be a liar. The prohibition would also include syncretistic practices in worship for such practices indicate that God is not sufficient in what He can provide and offer to His people. But the prohibition would also include any action or word that speaks falsely about the character of God. Thus, Christians today could break the third commandment when they preach a gospel that is legalistic or moralistic. Christians today could break the third commandment when they use Scripture to further their own agendas, making God out to be a leveraging device to gain political or social prestige. The third commandment could be broken by those who preach a health, wealth and prosperity gospel, for they misrepresent the character of God to a world that is broken and lost. But the third commandment can also be broken by believers who fail to indicate by their lifestyles that they are a people set apart to God. When the church looks like the world it is misrepresenting God to the world and it is this misrepresentation that lies at the heart of the third commandment.
