Religious identity development is highly influenced by contexts. This influence is even more powerful for young people who grew up in strict religious contexts because of the prominence of orthodox beliefs and practices in everyday life. This article presents which contextual factors were influential on the religious identity development of 18 emerging adults who grew up in strict Reformed contexts in the Netherlands. Moreover, it presents characteristics that led the participants to consider the influence as positive or negative. In the study, the perspective of the emerging adults was central, and through in-depth life story interviews, contextual influence was explored.
