"I can't really put it in one sentence because although on one hand Preacher is about faith and yes it is also about, I suppose, the search for God, the search for faith and the manipulation and the abuse committed by figures in whom I suppose people have faith"

In this quote, Garth Ennis acknowledges that Preacher can not be accurately summed up in just one sentence. He discusses that on one hand, the comic book series has to do with faith and the look for God. Nevertheless, he also explains that it explores the darker side of religious beliefs, exposing the manipulation and abuse that can be committed by those in positions of religious authority. It appears that Ennis is attempting to communicate that Preacher is a complex and nuanced work that explores both the favorable and negative aspects of faith, along with the extreme lengths some will go to in order to support their beliefs.
