I live in a Christian household; my parents and my brother are all Christian, but I am not. I considered myself one as a kid but decided I was atheist a few years ago. Because of this, I have been baptized and “saved” when I was younger.
Now that I am wanting to work with demons and other gods, would all of this affect my ability to communicate with them? Would it drive them away? If so is there any way to fix this?
No, it will affect nothing. There are plenty of Christian magicians that evoke spirits just as much as there are atheist and heathens that do so. It really doesn’t matter. You will still be able to communicate once you develop the ability.
It is important to understand that no particular godform, Christian or otherwise, will drive a spirit away without your intention to do so. A banishing ritual that calls on YHVH, or angels, or demon kings, is nothing without the intention of the magician to back it up. You are what powers the magick, not an external god.
Full on Christians can still summon demons. What you do( or in your case use to do) in your spare time is irreverent. It’s not like once you’ve been baptized Jesus stands outside your house holding a sign saying “Fuck off he’s mine”
The act of being sprinkled or dunked in water holy or otherwise doesnt magic away the demonic or effect occult rituals. The immersion is symbolic.
Christian Baptism supposedly signifies the end of your old way of life and rebirth and was employed by many ancient cultures not just Christians or the Catholic church as a ritual of purification and would have no bearing on your current beliefs or traditions, your current intent are more important than a meaningless ritual.
