Betty, you and clearly the author really don't understand what Opus Dei is and how it works.  You try to pass on these quotes as if they're written on stone tablets. 

There are married lay people who are members of Opus Dei.  There are many many many more lay married who simply attend what are called "means of formation" of Opus Dei (a once a month,  opportunity for Confession, or maybe a weekend retreat).

Romero attended such events. He wasn't in Opus Dei. 

People attend these events because it helps them be better husbands, wives, fathers, mothers, workers,

There is no top-down political instructions given to married, unmarried or even priests of Opus Dei on how or what to do in their own public/political life. 

I am a member of Opus Dei, and the types of things the priest who helps me asks me about my professional life is:  Have you and your wife talked about these travel demands and their effect on the family?  When you return home how can you make her life more pleasant?
