You misunderstand...Opus Dei's emphasis is on the "ordinary" vocations...that is, in the world...not in a club, not as a priest, not as a religious.   Big misunderstanding here. 

How to live out one's vocation as a secular newspaper editor, a mortician, a surgeon, a mother, a husband, an engineer..."all paths". That's the focus. 

How to turn all lecit occupations into opportunities to love God in every moment of the day. 

That's why most people in contact wtih Opus Dei (not just its members) don't hang around the parish...they see their work in the home, in the neighborhoods, in the swim team they're coaching as where God wants them to spread the Christian tone and message.
