The Protestant work ethic promotes excellence. But what is the connection between Protestantism, work, and excellence? The pioneering sociologist Max Weber was the first to draw attention to the Protestant work ethic. In his book The Protestant Ethic and the Spirit of Capitalism, published in 1904, Weber studied the phenomenal economic growth, social mobility, and cultural change that accompanied the Reformation. He went so far as to credit the Reformation for the rise of capitalism.
Usually, he said, religion is otherworldly. But the Reformation doctrine of vocation taught that religion is to be lived out in this world. Weber did not completely understand the doctrine of vocation. He had the idea that the early Protestants worked so hard so as to build up evidence for their salvation. But the early Protestants knew better than anyone that their salvation had nothing to do with their works or their work, trusting in the grace of God through Christ alone.
Weber also assumed the early Protestants were ascetics. While their hard work inevitably made them lots of money, he said, their moral scruples prevented them from spending it, at least on worldly pleasures. So instead, they saved their money, put it in banks, and invested it. That is, they transformed their money into capital, thus creating capitalism. There may be something to this, but modern research has shown that the early reformers — despite the stereotype of “Puritans” — were not particularly ascetic, a quality that better describes the medieval Catholics they were reacting against.
