Can't refute the veracity, so attack the messenger. 
Here are the direct quotes: "Opus Dei’s free reign within the Catholic Church began after it helped install Karol Wojtyla as Pope John Paul II" and "Of all the groups that are engaged in the U.S.-sponsored campaign against liberation theology [in the 1980's is part of the article] none has played a more significant role than Opus Dei." After keeping these quotes for so many years and using them so often, I'll admit some quotations marks got shifted to the wrong locations along the way and I won't make the same mistake again.
