WARNING! DO NOT, I SAY, DO NOT EVER CONFRONT SUPERNATURAL EVIL WITHOUT INVOLKING THE NAME OF JESUS. Why? Because the supernatural, both good and evil are FAR more powerful than humans. They, on the other hand, FEAR AND TREMBLE AT THE NAME OF JESUS. Why? Because Jesus is the mighty Lord, the Christ, and the only BORN SON OF THE LIVING TRUE GOD, JEHOVAH, CREATOR OF HEAVEN AND EARTH AND EVERYTHING IN THEM.
actually, if you invoke the name of the demon itself, you can control them. jesus even evidences this when he addresses hasatan by name. it's a pretty good way to get them to go away: ask them their names, and then address them by name and tell them to get lost.
and no, demons are not more powerful than humans, they're actually weaker because they have no freedom of choice, which is WHY you can order them away. the "power" just comes from being skilled at practical magic, and their incoporial nature.
so what's the prefered language in which to rebuke demons? hebrew? aramaic? latin? greek? i know exoricisms tend to be done in latin.
