But did Vatican II actually abandon the Latin Mass? I don’t think so. I think it was some unorthodox bishops who did so.
Vatican II promoted and encouraged Mass in the vernacular.
I don’t know whether or not it is a coincidence, but the huge problem with pedophile priests (for the most part) occurred after Vatican II.
Seems to me that the liberals really lowered the bar with respects to the standards and discipline of the Church.
Vatican II made it possible, giving cover to the bad guys. Many key documents were written in a vague and flabby way that practically begged for (and may have been intended for) a perverse and anti-traditional interpretation.
