The Church, supposedly governed from the Vatican, is hardly a universal one. In creating a new religion based not on God, but on humanist fickleness, all tenets and rubrics were tossed out the window including the language that bound all 'Roman Catholic' Churches together. That, of course, was Latin.
Pointing out the fallacies of the Eastern Orthodox Churches is rather like the people living in glass houses tossing rocks at others.
The fact is that an entirely new religion was created due to and subsequent to Vatican II and those 'popes' following that heresy will have a rough time explaining to their Maker the necessity for allowing change after change after change to be enacted.
Nonsense...the changes made by Vatican II were in rubrics,ceremonies, church layouts....there were no changes to Dogma nor anything of real consequence....I didn't like many of them, but in a 2,016 year old institution, they were basically pretty minor.
