I have heard they do, but I think it depends on the religion. I have what people have called a seers stone birthmark on my elbow and a devout (born again) Christian said it has to do with my ?great powers?. My mark is literally the size of a small stone and is raised from my arm. Thankfully as I grew up the mark didn?t, it was a constant reason to harass me as a kid.
I never got curious enough to look into it, but I have also heard some people in the magickal world say that it is a mark of one that has abilities. I have been told I have many natural abilities and I know I can see and talk to spirits, but they usually only talk to me if they want me to do something for them, otherwise they just walk past. I can see aura and have future knowledge, but whether or not it has to do with the mark, I don?t know.
I?m not sure if that helps you or not. Good luck.
