It does go a bit beyond green tea, though. Here are extracts of how the World Council of Churches defines ecumenical dialogue :
As for dialogue not resulting in conversions, I’m the living proof of the contrary (even though I’m technically “reverting”, none of it would have happened without ecumenical dialogue).
Etymologically dialogue means a conversation; but a conversation with an aim: to discover the truth.
Dialogue is not merely “discourse”. It is primarily a way of being together in charity, which gradually changes and renews the atmosphere essential for a joint profession of faith; where profound exchanges of thought and expression can achieve something which goes beyond clarity of conversation or individual conviction.
If not for a common discussion in charity with an aim toward truth and unity, I am not sure what can bring unity to Christianity. It is probably the best option we have.Dialogue is not a confrontation between Churches which are concerned about their own positions and their own structures. It is their meeting and collaboration in a common task, an effort to bear joint witness, a desire to obey the Lord whose Will it is that they should be one so that the world may believe.
