Theologians have an allergy to the science of economics. They will quote philosophers and sociologists all day long. But they refuse to read any economics, the best developed and most useful of the social sciences. Even when they think they have given the science a chance, it's easy to see they haven't. For example, when Craig L. Blomberg, Professor of New Testament at Denver Seminary, wrote "Neither Capitalism nor Socialism: A Biblical Theology of Economics," he argued that he had studied and his views were based on sound economics. They were not.
If theologians are not Marxists, most will insist like Blomberg that the Bible is neutral on the question of capitalism verses socialism. That doesn't explain why theologians from the 16th century until the late 19th century proclaimed laissez-faire capitalism as Christian economics.
