What evidence have you however for saying that "they go for power and elite and not for the true resistance against perversion and subversion of the Holy Roman Catholic Church by modernism, liberalism and ecumenism"? From my own acquaintance with them and from reading what I take to be well-informed comment about them in the news media, from both Modernists and Traditionalists, they are seen as a significant obstacle to the "Spirit of Vatican II" element and are hated by them. The only fault I find with them is their complete adherence to the NO liturgy.
There is no evidence of Opus Dei working for the good of the Church (ie. 'spirit of Vatican 11) ouT side of their own circle.
The compromise of Opus Dei can be easily demonstrated by pointing out their adherence to the Novus Ordo. No matter how many smells and bells they add to it, I don't think anyone who celebrates the NO (given the theological implications thereof) can be considered traditional, and that includes Opus Dei.
I asked the following question (which he could not answer) to a nephew who is currently fooling around with Opus Dei.
"Given that permission was granted for the Latin Mass of the 1962 Missal by JP2 and Ecclesia Dei in 1988 and given that Opus Dei is a personal prelature and thereby does not require permission of the local bishop, how come Opus DEi priests do not say the 1962 Mass now and why are they saying that they will when the Motu Propio of B16 comes out?"
They are currently renovating a suburban parish church in Melbourne to the tune of $4million dollars ($2 million from the taxpayers of Aust. And the other $2 million from their 'loyal supporters') "You should see the High altar!! It is beautiful!" they all gasp ! THEY DON'T USE IT.
