“While expressing their support for ecumenical work, the cardinals said that sharing in Communion signifies a full accord in faith, which in reality does not exist.”
The cardinal is of course absolutely correct, which is why some of us Orthodox wonder why there is a seeming insistance on the part of some bishops that it is appropriate for Orthodox to receive communion in Roman Catholic parishes. We are clearly very close; we recognize each others sacraments, the Apostolic Succession of the bishops and the validity of each others orders, but we are not in full accord on matters of dogma.
The way we see it, some are trying to use a shared Eucharist as a tool of unity rather than the perfect symbol of it. God willing, that time will come, but its not here yet.
That's right, Kolo mou. The Eucharist is an expression (symbol) of unity and not a means (tool) of achieveing it.
