Christianity had a major impact on developing a strong work ethic. Pre-Christian perspectives in Greco-Roman and Hebrew societies viewed labor as demeaning and only for slaves, whereas Christianity teaches that labor is honorable, a calling from God, and that laborers deserve fair wages. Key Christian figures like Martin Luther and John Calvin further developed the idea that work has dignity, property rights should be respected, and profit-seeking can be honorable. The Christian perspective is that God designed work and calls people to labor as their vocation, bringing dignity to all jobs and blessing to employers.
