To share communion with your brothers is to honour our Lord.

There is a lot in your request which saddens me and it opens some complex issues. I'm going to try to help, though not necessarily in the way you hope.

The path to Satan need not be difficult. He is there. He sees you and hears you and feels you. The moment you ask Him to be part of your life, He was already there.

Following Satan is likely the most oppressed philosophy humans embrace. As such, trust and sharing is made more difficult than any other by a hundredfold. To open ourselves to strangers and help them is to risk being hurt in all the ways that anyone helping a brother can be hurt, and in ways that no other fellowship can. Exposure as a Christian, Bhuddist, or even Pagan, might get some funny looks and a little derision at worst. Exposure as a worshipper in Satan can blow up a person's life in ways like no other. To throw open your life to someone you haven't known for a long time is accepting care of a social bomb.

So the best I can offer is to look for Satan internally, and serve Him as you find it in your heart to serve. You don't need anyone to tell you how to find Him, or how to worship Him. You are already a spark of the universe and therefore a part of Him. He sees you already, and He loves you already. He doesn't need slaves, He needs the love of His sparks. He needs us to do what we can to make the universe joyful for every spark. Be His soldier, carrying His torch, seek not to be His slave.

That is a phenomenal test of the body's capacity. I think it will take a strong Soldier of Satan to challenge you. I don't think I have filled that many men with Satan's spirit in nearly half a century of trying.
