Just the Protestant Work Ethic, which is pure Calvinism.
> Central to Calvinist belief was the Elect, those persons chosen by God to inherit eternal life. All other people were damned and nothing could change that since God was unchanging. While it was impossible to know for certain whether a person was one of the Elect, one could have a sense of it based on his own personal encounters with God. Outwardly the only evidence was in the person's daily life and deeds, and success in one's worldly endeavors was a sign of possible inclusion as one of the Elect. A person who was indifferent and displayed idleness was most certainly one of the damned, but a person who was active, austere, and hard-working gave evidence to himself and to others that he was one of God's chosen ones (Tilgher, 1930).
> Calvin taught that all men must work, even the rich, because to work was the will of God. It was the duty of men to serve as God's instruments here on earth, to reshape the world in the fashion of the Kingdom of God, and to become a part of the continuing process of His creation (Braude, 1975). Men were not to lust after wealth, possessions, or easy living, but were to reinvest the profits of their labor into financing further ventures. Earnings were thus to be reinvested over and over again, ad infinitum, or to the end of time (Lipset, 1990). Using profits to help others rise from a lessor level of subsistence violated God's will since persons could only demonstrate that they were among the Elect through their own labor (Lipset, 1990).
> 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).
