 Its full title is Hunangofiant Rhys Lewis, Gweinidog Bethel ("The autobiography of Rhys Lewis, minister of Bethel").It is generally agreed to be the first significant novel written in the Welsh language, and is to date one of the longest.It deals with the issues of evangelical Christian faith in a rapidly changing society affected by increasing exposure to outside influences, industrialisation with the inevitable strife that follows, and (perhaps most dangerous of all) the adoption by mainstream popular culture of certain aspects of Christianity whilst completely misunderstanding the essence of it.
