The dedication ritual is a one time deal, you should not repeat it.
Even if you messed up, work hard from now on. Engage in spiritual warfare and spiritually empower yourself. Work for Almighty Lord Father Satan and strive to become the GOD you are. Meditate and do yoga daily. Expand your knowledge by reading the Joy of Satan website and actively work to spread the truth.
Even if your parents do not approve of Satanism, keep training. They are deluded and did not realize the truth of Satanism and the path to GODHOOD that Satanism is. If possible, explain the truth of Satanism to your parents and try to get them to understand how Satanism is the true religion of humanity. Satanism can even be scientifically explained, unlike Christianity, as brainwaves can be picked up by machines and read and sound can shatter objects if vibrating at the right frequency among many other scientific phenomenon.
If your parents are too programmed and will not approve of Satanism, then BE CAREFUL with your spiritual empowerment. You would not want to get kicked out of the house. There are many tips on the groups regarding how to hide training and explain spiritual activities without causing programmed parents to become alarmed. Meditation can be done after other people in the house are asleep or before people get up. Keep working hard to become a god and make your father, Almighty Lord Father Satan, proud by becoming a god.
Hail Almighty Lord Father Satan!!
Hail all of the True and Mighty Gods of Duat!!
