And Brother, perhaps you can tell me "who" in particular is privileged?  And in what way.

Is it the numerary member of Opus Dei who then becomes a priest?   Most Opus Dei priests because they were first numerary members have had a professional career as well.  

They are scientists, engineers, professors of various types, lawyers, even MDs.  When they become priests, they put most of that work behind them in order to serve the Church with total availability. 

Is it just the straight numerary/unmarried members?  As I said most numeraries STILL work in the world...they are doctors, scientists, researchers, lawyers, engineers, business people.  Thyey turn over their pay to Opus Dei, and most spend most of their evening and weekend time providing formation to members of Opus Dei or to friends of Opus Dei.   What's the privilige here?

Or is the married members?
