Economic Impact of Pentecostalism

Pentecostal churches surveyed in the Gauteng and Durban regions in 2007-8 tend to be characterised by a sense of spiritual encounter, joy, happiness, and optimism among congregants. These reactions appear to correlate with feelings of self-confidence and self-esteem …. that create high levels of personal energy that manifests itself in a more intense family life, working life, and business activities.  This closely resembles some important aspects of original Calvinism (as described by Max Weber): a sense of purpose and confidence in worldly engagement, strengthened by this worldly asceticism.
