<P> The author of Hebrews reviewed God's promise to Abraham as assurance that outstanding promises will yet be fulfilled . "Human beings, of course, swear by someone greater than themselves, and an oath given as confirmation puts an end to all dispute ." In the case of the promise of God to Abraham, God swore by his own name to guarantee the promise, since there was nothing greater for him to swear by . Philo pointed out that it is natural that God would swear by himself, even though this is "a thing impossible for anyone else ." </P> <P> Similar to the events described in the Book of Daniel, the Book of Revelation includes a description of an angel who swears by God to the truth of the end - time events being revealed to John . </P> <P> O Lord, our Lord, how majestic is your name in all the earth! </P> <P> The Catholic Church teaches that the Lord's name is holy and should be introduced into one's speech only to bless, praise or glorify that name . The name should be used respectfully, with an awareness of the presence of God . It must not be abused by careless speech, false oaths, or words of hatred, reproach or defiance toward God, or used in magic . Since Jesus Christ is believed to be the Messiah, and "the image of the invisible God," this commandment is applied to the name of Jesus Christ as well . </P>

Don't put god's name in vain
