So basically everyone are dragons, dragon slayers, gods, god slayers, demons and demon slayers because there is never enough spice for Mashima at this point
Let´s be fair, god slayers were just put into the story to work as a superior counterpart to the Dragonslayers, same can be said about Gray´s demonslayer abilities.
We haven´t seen a single god (or Kami) in this story besides the one Natsu onehit and Ankh Sheram. God Slayers at this point were all worthless and the "Devil Slayer Magic" is book taught.
Silver mentions that he learned "amazing demonslaying magic" from a book, the same applies to at least the godslaying powers of Shelia.
It´s just there to sound cool.
