Christians (and others) are losing the battle because the buzzword is "rights" instead of "duties." And we're losing rights even while we talk incessantly about them. Mary Ann Glendon is right about that. Consequently, a viciously positivistic conception of law has taken hold, and its only currency is power.
This is highly useful. At the end of the day, we have two competing views of totalizing reality. The huge problem is that, whether talking about nature or the supernatural, there's only one reality. A person made for an ultimately spiritual end who gets "religious" about the stuff of Earth is more dangerous than an army of fire and brimstone preachers, and almost infinitely so, the nightmares of secular leftists notwithstanding.
Today we talk about "freedom" in only one sense: the freedom from coercion. But there are others. There is the freedom to do something, like write this blog post. But any freedom to do something only serves a freedom for something, like peace, justice, loving God, et cetera.
Food for thought.
