text: Technically in the sense that there is no resurrection without the cross. But it is rarely referred to that way. The Orthodox Liturgy is about what hasn't even happened yet--the transfigured world. This is the entire meaning of iconography, to make the unseen real, and why it is part of our theology, not just pretty pictures. When you receive communion, you are receiving the transfigured Christ. Some people may argue the finer points and there may be some variation from region to region but it has been said many times about the two liturgies--one seems forever centred on Calvary; the other on Pascha. 
  
  There is some parting of ways on the whole notion of atonement too, mostly a reaction to Anselm, but then, there are some Orthodox thinkers who think Anselm's ideas are correct. One thing for certain: you will always get lots of disagreement within the Orthodox church.
