Defense Against the Dark Arts 8: Goddess Circe
Lets look at the old English and Greek meaning of the word "Church"...
Well, it derives from the dutch word "Kerk" which derives from the Greek word "Kirke".
This word stems from the Greek Goddes "Circe" ( pronounced "Kirke") whom invited her victims into her house.
Then she confused them with herbs and changed them into pigs.
