This paper presents the results of a study on Street Pastors in Cardiff, capital city of Wales. Street Pastors are Christian volunteers who look after (intoxicated) people in the nightlife district. In so doing, they provide security through empathy and care. The motives of Street Pastors to engage with partygoers are multi-layered, but their personal faith appears as a key explanation. A certain kind of orthodox ‘certitude’ of being safe (and saved) in a Higher Power gives the pastors their strength to go out on the street, face the unknown and feel compassion for their fellow citizens.
