I agree. But it's odd what you describe, because O.D. has a reputation for being "secretive" because -- as it was explained to me -- members are supposed to be Catholics first, not "Opus Dei members" or "Opus Dei Catholics", and therefore not in-your-face about their involvement. Being elitist about it is to miss the whole point.
I guess some people miss the point, whatever that is. There is always the temptation to form exclusive groups for no other reason but to be exclusive. For people who are not worthy enough in their own minds and need to be “special.”
