The only requirement to be a satanist is Just believe Satan's first lie.
Genesis 3:4-6
4And the serpent said unto the woman, Ye shall not surely die:
5For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
Summarized: Believe you will never die, and that you can be your own god.
Remember your reward for being a satanist is a never ending torturous and continuous spiritual and painful death.
No because extra ordinary claims require extra ordinary evidence, no evidence exists for god or myself,(oops i mean Satan), but simple testing shows he/she/it doesn't exist
Here is a simple god test
1. God you will post on every Forum, Blog, FAQ and Yahoo Answers Category on the Internet in exactly 30 seconds (GMT) after this post has been made. You will post world wide and your post will state the following:
"I am god, I exist"
A) In every Forum, Blog, FAQ and Yahoo Answers Category must have the same exact time stamp based on human time GMT.
2. Mr. Devil you will post on every Forum, Blog, FAQ and Yahoo Answers Category on the Internet in exactly 30 seconds (GMT) after this post has been made. You will post world wide and your post will state the following:
"I am devil, I exist"
A) In every Forum, Blog, FAQ and Yahoo Answers Category must have the same exact time stamp based on human time GMT.
This simple test shows the devil does not exist, there is nothing that states we can not test god or we can not test the devil and if either does not exist then both do not exist. It is that simple
If this is a serious question then no, you don't need to be circumcised to be a satanist, as much as I don't believe in Satan you should do what your true faith is. If that is Satanism then all luck to you. One thing I'm certain ed of that is, if you want to become an official satanist you must have a ceremony either by cult or anti Christ church (If there is one by your local area) Otherwise groups of well experienced satanists can make it for you, I'm unsure what it is they have to do, I think you have to be touched or marked by the devil.. at least that's what they did in earlier times..
Good luck and I hope this isn't a trolling post
You can always be Jewish...Or wait Christianity is Jewish, Except Jesus was a Blue eyed Anglo Saxon that hated Jews, But Jesus loves you, unless your a bad sinner, his dad hates sinners he refuses to be in their presence, but Jesus Doesn't mind being in the presence of sinners, he died for them, Jesus and his daddy are the same person, but Jesus loves his father that's why he prays to himself, I mean his father. Jesus use to say things like "Oh Father why have you forsaken me?," and all his followers were impressed about how he prayed to himself and asked himself why he kept forsaking himself." I guess none of this makes sense, but the bible makes perfect sense, and without flaw, just go to church, and ask Jesus into your heart to be your lord and savior, then attend church, remember to vote for the right candidate that the church, I mean Jesus and his daddy want you to vote for, its the good christian thing to do...
