Nouwen was trained in psychology. Since his book came out in 1972, however, I think he may have invented the term. I didn't see anything before the 90s in a quick Google search on the term. From a website devoted to Nouwen:

The Wounded Healer: Ministry In Contemporary Society (Doubleday, 1972).

What does it mean to be a minister in contemporary society where men and women who want to be of service find the familiar ways crumbling and themselves stripped of their traditional protections? Nouwen addresses the question: "After all my attempts to articulate the predicament of contemporary humanity, the necessity to articulate the predicament of the ministers themselves became most important. For ministers are called to recognize the sufferings of their times in their own hearts and to make that recognition the starting point of their service. In four parts: Ministry in a Dislocated World/Ministry for a Rootless Generation/Ministry to a Hopeless Individual/Ministry by a Lonely Minister.

I believe Fr. Neuhaus' point was that -- as you state -- it is inappropriate to religion. Nouwen apparently disagreed.

If Cardinal Law used that term I am confident he had no idea what it really meant. The term 'wounded predators' would be more accurate.
