text: Dave Phil, Eastern Orthodox liturgical practice and theology is almost entirely unchanged since before the schism of 1054. Since prior to that date, the East and West were fully united in one Great Church (as it is sometimes called), and since in the Great Church there was mutual acceptance of one anothers difference practices and theologies, those divergent practices and theologies are completely within the Catholic Tradition. Therefore, it is very sound theological practice to look to the East an to those divergences when trying to more deeply understand the Western strand of the same broad Tradition. 
  
  We saw that phenomenon in practice during the last two synods on the family. The liberal wing in that synod very much wanted to import theological understanding from the East as a foundation for the merciful pastoral practice Pope Francis wanted to introduce. Sadly, only a simple majority was with him, not the requisite 2/3's. 
  
  Please be nice. Out of the mouth and all that.
