 Irish writer Garth Ennis then took over the title in 1991 , again from 2000 AD , where he had been working on Judge <unk> . He proceeded to write the longest run for any writer on the title . His take on the title was more personal than Jamie Delano 's , with John 's relationships coming to the fore . It also had a strong religious theme , with John 's dealings with the First of the Fallen , and some storylines , such as the relationship between an angel , <unk> , and a <unk> demon , Ellie , would go on to be used again as a major plot device in Preacher , one of his most popular works . He also references the music of The <unk> and the poetry of Brendan <unk> , both of these being relevant to Ennis ' Irish heritage .
