I did read the book called “Demons of Magick” and it actually made me a bit confused because in the book it was explained that for working with demons we should call for angels first (in order to safety and control the demon or getting verification to have the power to make the demons serve us) and then evocate the demons. Also this book is just using Judaism, Christianity and God for making magic possible. Now what makes me confused is that I though religions are bulls*** and useless, Im actually comparing this book (which is suggested here) with the videos made by Lady Savanna. In the videos it was told that using religious books is in vain and we can communicate with these ancient gods and enjoy it as long as we respect what were doing.
So my question is do we have to call angels in order to be protected and not get hurt? Actually if we should/can call the angels why do we need demons at all, thats stupid. TBH Im asking these cause I just wanna work with ancient gods with no fear or worries but I cant feel safe as long as theres words of angels helps to be protected from demons. :l

Sweet Regards
