Blasphemy is defined as cursing the Creator. This prohibition comes to teach us not to speak evil against G-d nor to detract from His exaltedness in any way by intentionally using words to lessen the respect due to His name. This crime is considered so heinous due to the fact that, while the Idolator worships another diety out of ignorance, the blasphemer acknowledges the True Creator, yet denies His Goodness and Holiness. It is irrelevant which language is used, or even if it is not a proper name of G-d, but only an epithet or attribute of Him. Speaking out against G-d in any way is considered Blashpemy.

    Another example of blasphemy is the notion that the universe is subject to a massive heavenly battle that is evenly balanced between good and evil, heaven and hell, G-d and the Satan. This mythological notion denies the fact that G-d's power is Omnipotent and that He is the L-rd and Master of All, including Satan. The finest example of this fact is the first chapter of the book of Job. In it, it states that "there was a day when the sons of G-d (the angels) came to present themselves before the L-rd, and Satan also came among them." Job 1:6 Later in the same chapter, Satan petitions G-d to allow him to persecute Job as a test of his loyalty to heaven, and G-d grants the petition. In other words, Satan could not even do so much as tempt Job without the direct approval of G-d Himself, and there were limits to what G-d would allow. To think of Satan as hating G-d and doing anything against His Will, is mythological. In fact, G-d continuously grants existence to all creations in all universes, and if He ever willed something not to exist, He would simply stop granting it the power to exist. To think of G-d and Satan in a proverbial dual with one another, locked into primordial combat, is tantamount to blasphemy in that it denies G-d's Omnipotence and denigrates his infinite majesty.
