"Is Liberalism a Heresy?"

My Notre Dame colleague, Francesca Murphy (Theology) says "no," in this very worthwhile First Things piece.   She concludes:

Liberalism is no heresy, and the market exchange from which it emerges does not sin against the light. It is a healthy byproduct of Christianity, and the only means by which Christians can fight ­Marxist-capitalism, the stage-managed freedom in which the benevolent will of the powerful consults reason, discerns what people “truly” need and want, and then superintends over and administers the always vulnerable freedom of ordinary people. If one were searching for Gnostic heresies, surely this technocratic political economy, which is very much with us today, is a good candidate for anathema.
