From the Cathedrale Notre-Dame de Paris liturgie:
"The bread distributed during mass has a high significance for Christians: it is the body of Christ their Lord and God. If you do not share our faith in the living presence of Christ in the eucharistic bread, we ask you not to join your neighbours at communion time."
I found it somewhat ironic to find a more inclusive welcome to the communion table at Notre Dame than we're getting in many corners of the Anglicandom. Who'd have thunk it?
