I see from the replies that many people regard the belief in satan as an ignorant superstition that surely no modern, learned person would be silly
enough to entertain.
Whether you believe in satan or not, I offer, for your consideration, the Rituale Romanum... also known as the Exorcism Rite.
Dating back to the 16th century Catholic Church, it was used even then as a last resort... when the priests had ruled out 'psychological' causes for
a suspected 'possession'. It's hard NOT to believe in something supernatural (and evil) when the suspected possessed person is eloquently speaking
an ancient language they'd never even heard of before, or babbling gibberish for 20 minutes, which when recorded and played backwards reveals
the person spouting off a long series of prayers. The priests believe that the saying of the prayers backwards (in this case, quite literally) is done
by the demon\evil spirit to mock Christ.
These phenomena, and much more, have been documented.
Here's the exorcism ritual, word-for-word, and here's hoping none of us ever need it.
Hear therefore and fear, O Satan, enemy of the faith, foe to the human race, producer of death, thief of life, destroyer of justice, root of evils,
kindler of vices, seducer of men, betrayer of nations, inciter of envy, origin of avarice, cause of discord, procurer of sorrows. Why dost thou stand
and resist, when thou knowest that Christ the Lord will destroy thy strength? Fear Him who was immolated in Isaac, sold in Joseph, slain in the lamb,
crucified in man, and then was triumphant over hell. It is hard for thee to wish to resist. It is hard for thee to kick against the pricks. Because
the more slowly thou go out, the more the punishment against thee increases, since thou despises not men but Him who is Lord of the quick and the
dead, who shall come to judge the quick and the dead, and the world by fire.


your joking right?
