Nash served as a professor for over 40 years, teaching and writing in the areas of worldview, apologetics, ethics, theology, and history.

[2] Following his doctoral work, Nash became the Chairman of the Department of Philosophy and Religion and Director of Graduate Studies in Humanities at Western Kentucky University, where he served for 27 years.

He taught overseas classes, World Views in Hong Kong and Church History in London.

A public memorial service in Nash's honor was held at the Orlando campus of the Reformed Theological Seminary.

Liberation theologians have rejected the one system that offers real economic hope for the masses they wish to assist.

Instead, they have taken a path that will not only deny their people food but also deprive them of liberty due to socialism's central control.

An undesirable feature is noted in an alleged capitalistic society, and one where a market economy supposedly functions.

Von Mises' claims were strengthened by the fact that this is exactly what happened in cases such as the Soviet Union, where socialist states attempted to abolish all markets.

[13] Nash is a critic of the Christian left, particularly Jim Wallis, Ron Sider, and Tony Campolo.

[17] Nash states that the problem with this system is that it shuts off important signals that entrepreneurs might otherwise use in making economic decisions.

When the government owns the land, labor, utilities, factory, and other factors of production, it becomes impossible to tell how much it costs to produce a good or service.

He states that capitalism is a system of voluntary relationships which protect people's rights against force, fraud, theft, and violations of contract.

Nash retorts that capitalism is the one mechanism that neutralizes greed, as it forces people to find ways of serving the needs of those with whom they wish to exchange.

As long as greedy people are prohibited from introducing force, fraud, and theft into the exchange process and as long as they cannot secure special privileges from the state under interventionist or socialist arrangements, their greed must be channeled into the discovery of products or services for which people are willing to trade.

[21] Nash writes "Wallis's response to the Cambodian Communists' slaughter of two million men, women, and children was to deny the bloodbath and blame whatever else might happen on the United States.

One college president stated publicly that he would not hire any faculty for his school who were not in sympathy with Sider's position on Rich Christians in an Age of Hunger.
