Selection of an occupation and pursuing it to achieve the greatest profit possible was considered by Calvinists to be a religious duty. Not only condoning, but encouraging the pursuit of unlimited profit was a radical departure from the Christian beliefs of the middle ages. In addition, unlike Luther, Calvin considered it appropriate to seek an occupation which would provide the greatest earnings possible. If that meant abandoning the family trade or profession, the change was not only allowed, but it was considered to be one's religious duty (Tilgher, 1930).
