text: If all the Eastern Catholic Churches interpret all the Church doctrines in the same way, then why are there distinctly different Eastern Catholic Churches in union with Rome?  Eastern Rite Churches do not consider the difference to be merely in liturgical rite as Roman Rite Catholics often claim.  
  
  It was, in fact, the Eastern Melkite Rite that contributed significantly to Vatican II in regard to use of the vernacular language and concelebration in liturgy, collegiality and synodality in governance and a unique theological approach to Catholic doctrine.
  
  Archbishop John R. Quinn explains the East-West diversity in his book, EVER ANCIENT, EVER NEW: Structures of Communion in the Catholic Church.

  As for possibility of a Vatican II Rite/Church, Eastern Rite Churches now in union with Rome were once condemned as heretical.  https://RiteBeyondRome.com
