In 1958, American sociologist Gerhard Lenski conducted an empirical inquiry into "religion's impact on politics, economics, and family life" in the Detroit, Mich., area. It revealed, among other insights, that there were significant differences between Catholics on the one hand and (white) Protestants and Jews on the other hand with respect to economics and the sciences. Lenski's data supported basic hypotheses of Weber's work The Protestant Ethic and the Spirit of Capitalism. According to Lenski, "the contribution of Protestantism to material progress have been largely unintended by-products of certain distinctive Protestant traits. This was a central point in Weber's theory." Lenski noted that more than a hundred years prior to Weber, John Wesley, one of the founders of the Methodist church, had observed that "diligence and frugality" made Methodists wealthy. "In an early era, Protestant asceticism and dedication to work, as noted both by Wesley and Weber, seem to have been important patterns of action contributing to economic progress. Both facilitated the accumulation of capital, so critically important to the economic growth and development of nations."[23]
German theologian Friedrich Wilhelm Graf notes: "Sociologists of religion like Peter L. Berger and David Martin have interpreted the Protestant revolution in Latin America as implicit support of basic elements of Weber's thesis. [...] At any rate, many pious persons there interpret their transition from the Roman Catholic church to Protestant Pentecostal congregations in terms of a moral idea that promises long-term economic gains through strong innerworldly asceticism. The strict ascetic self-discipline that has been successfully institutionalized in the Pentecostal congregations, the readiness to work more and with greater effort and to take less leisurely attitudes lead many Pentecostal Christians to believe that their new faith in God is supported by their economic successes."[24]
In a journal article published in 2019, scholar of religion Benjamin Kirby critiques Peter L. Berger's analysis for its over-emphasis on the influence of Holiness-oriented Pentecostal churches, neglecting the growing influence of neo-Pentecostal churches across the globe. Kirby argues that it is difficult to draw parallels between contemporary neo-Pentecostals and Weber's ascetic Protestants, specifically because the former group of practitioners, many of whom espouse Prosperity theologies, often do not exhibit the same commitment to "sober economic virtue" and "rational bourgeois economic life" as Weber's Calvinistic Puritans. Nevertheless, Kirby stresses that Weber's text remains important for understanding enduring affinities between Christianity and capitalism. Kirby posits a "new elective affinity" between contemporary Pentecostalism and neoliberal capitalism, suggesting that neo-Pentecostal churches may act as vehicles for embedding neoliberal economic processes, for instance by encouraging practitioners to become entrepreneurial, responsibilised citizens.[25]
