I know you’re no fan of JP II but my question is do you have any specific issues with the work of Opus Dei?
The topic of Opus Dei only came up because we were discussing all these "new movements" that have been encouraged by the pope, things like the Neocatechumal Way. Wideawake suggested that these groups were exaggerating their degree of support from the Vatican, but I pointed out that Opus Dei could be included under the same rubric, and that you could hardly exaggerate the degree of support they have received from the Vatican, considering how extensive it has been, including creating an entirely new juridical category for them -- "personal prelature."
As far as Opus Dei themselves, I have mixed feelings. Certainly they are much to be preferred over some other "new movements" like the charismatic movement, the Neo-catechumenal way, and even the Legion of Christ. But I do have reservations about the way they have been shoved forward so vigorously, and the way that Msgr. Escriva's cause for canonization was expedited so quickly.
Opus Dei is a cult. Four of my siblings (who even as young children were faithful, practicing Catholics) went to Opus Dei schools. The message that was delivered was you either join us (become numerary and supernumeraries)and do everthing we say (wear horsehair undershirts, etc.) or you will be expelled. Needless to say they were expelled.
