Opus Dei is a form of Eliteism and has no place in The Catholic Church.
Reminds me of the Book “Animal Farm”, in which “All pigs are equal,but some pigs are more equal than others”.
Makes me sad.
Obviously the Popes disagree with you.
Opus Dei has had plenty of critics, almost all of them leftist dissenters, so you may have gotten a false impression of them.
I had plenty of contact with members of Opus Dei, including one of their priests, when I was in college, and in graduate school, and I kept up some of the contacts afterward. I also read St. Josemaria Escriva’s biography. They are all orthodox Catholics, in my experience, and nothing secret about it.
