found this on some spiritualist site.. funny as crap 
Introductory Pact
I relinquish the ownership of my immortal soul into the keeping of Satan, the Master of Evil Demons, Commander of all Ungodly Forces and Unclean Spirits, Inventor of the Sin, Eater of Souls, and Chief Torturer of all dead Heathens and Damned Christians. I furthermore give to him and his subservient creatures the rights and privileges and freedoms entitled to me by the Creator of the Universe, whose name I flout. I understand fully that I will live as a creature of sin and an artist of villainy and corruption in this world, and become a slave of evil in the next; property of the diabolic in both. I shall spurn and debase all things worthy and pure, and I shall make ruin my cause and calling. I shall indulge in joyous cruelties from the pettiest to the most maleficent. I swear that I shall curse the names of all the angels of the
host of heaven; and with the aid of my Liege, they shall hear me and be tormented thereby. I shall endeveor to commit all kinds of sin and crimes against the Enemy-who-yet-rules, succeed and blacken the soul of the earth. I am a blasphemy. I am one accursed. I am among the host of the damned.
This Pact, binds me to the Eternal Darkness that is Satan in a manner as irrevocable as his fall into the realms of perdition. There, with my new master, I shall remain in torment and unforgiven until the end of the world. In return for this sacrifice and for my denial of all that is good and redeeming, I will possess money in substantial quantities, the fulfillment of all of my lusts, and the destruction and degradation of all that opposes my whims. I shall overcome with blackness, succeed in monstrosity, vindicate all scorn, by breaking the Whole. In return for the additional corruption of other people, for every one damned and dead that I am responsible for directly, I shall have my life prolonged in health for another two years and a day. I fully understand the consequences of the signing of this most unholy pact; I proceed willfully, cognizant of my coming privileges and debts. I furthermore promise to fulfill my debt punctually and without resistance, nor will I pray nor plead for my soul in any way, nor attempt to have others plead in my behalf. I confirm this in this covenant more tightly knit than the bonds of life and death. May the Prince of Darkness take pleasure in my gift and my
betrayal, and use such to spread his reign further throughout the phenomenal world by annihilating the spiritual.

Anyway, I don't know if I believe in all the god devil stuff, but its fun to let your mind wander on it.
