Around the turn of the millennium a murder case took place in a small village in Sweden called Knutby. This case took place within a pentecostal church called Filadelfiaförsamlingen and the whole thing became huge in the media. Many mediasources refer to Filadelfiaförsamlingen as a sect for many different reasons. Later on a writer called Jonas Bonnier wrote a novel called “Knutby” based on this murdercase and Filadelfiaförsamlingen. Although, Jonas Bonnier does not refer to Filadelfiaförsamlingen as a sect in his novel like many mediasourses tend to do. Therefore this study seeks to examine if the pentecostal church Jonas Bonnier describes in his novel “Knutby” can be defined as a sect. To make this possible this study is going to use Roy Wallis and his definition of a sect. The first framing of a question in this study is about how the pentacostal church is described in the novel “Knutby” by Jonas Bonnier. The second framing of a question in this study is about whether the pentacostal church described by Jonas Bonnier can be defined as a sect or not according to Roy Wallis definition of a sect. The purpose of this study is to examine if the pentacostal church described by Jonas Bonnier can be defined as a sect according to Roy Wallis definition of a sect. This study refers to use a qualitative method as well as a deductive approach. The method is furthermore divided into five different steps and the analysis provides to be a content analysis. The conclusions of this study are divided into two parts. The first part of the conclusion concludes that the pentacostal church described by Jonas Bonnier is a small church with their own unique values and rules. Some of the pastors within this pentacostal church have a lot of power over the other churchmembers. The second part of the conclusion concludes that the pentacostal church described by Jonas Bonnier can not be defined as a sect according to Roy Wallis and his definition of a sect.
