text: There was not any printing press in the Second Century.  The Liturgy was adopted to the area [province] where the people WERE Christian and celebrated.  There certainly wasn't any Liturgical 'watch-dog' group over-seeing developments in the liturgy.  This was done, not only in Greek, but in other languages in which the Liturgy was celebrated.  At this time, there was no Eastern and Western Churches.  For example, in the Chaldean and  Assyrian Rites, there are no words of Institution of the Eucharist, no consecration.  This went on for centuries [yes, they were and are faithful Catholics].  It was acknowledged with an agreement only on October 26, 2001.  There were other places during the Liturgies, where there is reference to the words of Jesus.
  
  When the Benedictine Order was established, the monks undertook the task of printing by hand---Sacred Scripture and the Liturgy.  But there were mistakes as well in the hand printing.  When humans do anything, there are errors.
