The third commandment, contemplating God's name, may be the most misunderstood of all. This commandment covers the quality of our worship.
Many people think the third commandment deals only with euphemisms and swearing, but it actually goes much deeper than that! John Ritenbaugh explains that this commandment regulates the quality of our worship and involves glorifying God in every aspect of life.
John Ritenbaugh, suggesting that the prohibition against taking God's name in vain is the least understood commandment, asserts that the names of God (more than 250 mentioned in the Scriptures, eight of them concentrated in Psalm 23) represent the multitudinous characteristics, traits, attributes, or the very character or nature of God Almighty. Through the life, words, and works of Jesus Christ (The Way), we can see God the Father revealed. If we faithfully follow His example (emulating His life), we will not only find the Father, but also bring respect for God's character by our conduct. Eternal life is to know God by emulating His Character- living life as God lives life. Our most valuable asset we have is God's family name. When we bear God's name (which we acquire through our calling and baptism) we are also obligated to bear His character and nature, and not dishonor or blaspheme His precious name through our conduct.
