Imagine an Orthodox temple and a Catholic, an Orthodox icon and a Catholic, etc. We want them united, not side by side. If we put them side by side it will be an ugliness greater than putting a pyramid in Acropolis, precisely because their similarity is greater.

Cf. Catholic-Orthodox dialogue : Let us surpass each other in folly , The union with papacy – A Discussion , The union of the Churches is the best way to eliminate Christianity , Protestant and Orthodox iconography.
