>>2341657they are demons, they are hurt by it
nothing is created by some other not-created god or un-created God, because there is only one God who created all and he Himself is ex-nihilo.
Leading to the logical conclusion that, whatever those things are, if they exist, they are created that way or created good and later corrupted, or simply demons, which goes to the first point.
And all this means that they might operate outside the confines of the Holy Trinity, which all demons do anyway, but they are not unaffected, nor your own power, strenght and mental capacity is unaffected by prayer.
Nice try Satan, but not today.
