Orthodoxy cannot defend the capitalist system, for it is founded on the exploitation of hired labor. The capitalist system has augmented the productivity of labor and creative energy: that is good. But there are very clear limits to this good, and, consequently, to the extent of the Church’s cooperation. Christianity cannot and should not compromise with Black slavery, nor with the exploitation of child labor, practiced by capitalism in its beginnings.
