Rome and Orthodoxy: The Push Toward “One Cup”

In recent decades, ecumenical dialogue between Rome and Orthodoxy has increasingly spoken of:

“Sister Churches”

“Shared apostolic heritage”

“Incomplete communion”

Future Eucharistic intercommunion

Here the crisis becomes acute.

The Eucharist is not a tool of unity; it is the expression of unity already achieved. The Fathers never communed first and resolved doctrine later. They resolved doctrine before communion. To speak of “one cup” without resolving:

Papal supremacy

Filioque

Created grace

Doctrinal unilateralism

is to reverse the order of salvation.

Saint Paul warns:

“For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.” (1 Corinthians 11:29, KJV).

The fear among many Orthodox is not imaginary: that unity is being pursued sacramentally without repentance, and that the Eucharist is being transformed from a confession of truth into a diplomatic instrument.
