In the context of the economies of Newly Industrialized Countries, this article surveys the understanding of work in Islam and Hinduism and contrasts them with John Calvin’s notion of work and calling. The author analyzes Islamic traditions, classic Hindu texts, and Calvin’s Institutes and Commentaries. While Islam puts a premium on religious work, and Hinduism defines work in light of its caste system, in a Reformed worldview, God values all types of work, and workers are God’s stewards. This notion is of particular relevance to those involved in economic development.
